To provide a bid management device and a program capable of suppressing occurrence of a situation in which a fair order-reception business between an ordering operator and an order-receiving operator is hindered.SOLUTION: A management server 20 includes: a processing unit 21 that manages a bid for a bid target; and a storage unit 23. The processing unit 21 receives bid information including the bid target, a bid closing date, and information on a bid-desiring operator from an ordering operator terminal and stores it in the storage unit 23, and transmits the stored bid information to a bidder terminal 60 of the bid-desiring operator. The processing unit 21 receives, from the bid terminal 60, tender information including a bid price of the bid target included in the transmitted bid information and the information on the bid-desiring operator who presents the bid price, and stores, in the storage unit 23, the bid information in association with the bid information already stored. The processing unit 21 prohibits the bid price and a name of the bid-desiring operator, which are included in the tender information associated with the bid information for which the bid closing date does not pass among the bid information stored in the storage unit 23, from being displayed on an ordering operator terminal.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a bid management device and a program. [Background technology]

[0002] When a client requests construction work such as construction, civil engineering, or electrical work, the ordering company divides the requested construction work into several parts and concludes a contract with a contractor (subcontractor) for each divided construction work (see, for example, Patent Document 1). When there are multiple contractors who wish to receive the order for a single construction work, the ordering company selects a contractor to order the construction work from among the multiple contractors, taking into account the estimated prices submitted by the multiple contractors. Generally, a contractor with a lower estimated price has an advantage in receiving the order for the work. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-11106 Summary of the Invention [Problem to be solved by the invention]

[0004] A construction work representative (e.g., a sales representative) at a contractor may have the opportunity to contact multiple potential contractors and may be in a position to know the estimated prices of each potential contractor for the construction work. In this case, a situation may arise in which the contractor's sales representative gives some potential contractors an estimated price that is more likely to win the contract, taking into account the estimated prices of other potential contractors, in order to give some potential contractors an advantage in winning the contract. Specifically, the sales representative may include a commission known as a rebate (also known as a kickback) in the estimated price, and give some potential contractors an amount that is lower than the estimated price that is more likely to win the contract.

[0005] If a prospective contractor who has received a quote from the person in charge is selected as the contractor, the contractor will then invoice the ordering company for the amount of the quote they previously submitted minus the rebate, and pay the rebate directly to the person in charge without going through the ordering company. In this case, there is a risk that fair bidding between the ordering company and the prospective contractor will be hindered. Note that this issue can arise not only in cases where the bidding target is construction work such as construction, civil engineering, and electrical work.

[0006] A primary object of the present invention is to provide a bid management device and program that can prevent the occurrence of situations in which fair order-receiving operations between an ordering company and a prospective order-receiving company are impeded. [Means for solving the problem]

[0007] The present invention is configured to be able to communicate with an ordering party terminal including a terminal of a purchasing company that is a bid target and is operated by a person in charge of bidding operations for the bid target, and a terminal of the ordering company that is operated by a person in charge who has the authority to decide on a successful bidder for the bid target, A bid management device configured to be able to communicate with a bidder terminal, which is a terminal of a bidder who wishes to bid, a processing unit that manages the bids for the bid targets; a storage unit, The processing unit Receives bidding information from the purchaser terminal, including information on the bidding target to be ordered by the purchaser, the bidding deadline for the bidding target, and information on the bidders who have been permitted to participate in the bidding for the bidding target, and stores the received bidding information in the storage unit; The bidding information stored in the storage unit is transmitted to the bidder terminal of the prospective bidder included in the bidding information; receiving, from the bidder terminal, bidding information including the bid price of the bid target included in the transmitted bidding information and information on the prospective bidder who submitted the bid price, and storing the received bidding information in the storage unit in association with the bidding information already stored; prohibiting the bid price and the name of the prospective bidder included in the bidding information associated with the bidding information stored in the storage unit for which the bidding deadline has not yet passed from being displayed on the purchaser terminal; displaying on the purchaser terminal a selection screen in which the bid amount included in the bidding information associated with the bidding information for which the bidding deadline has passed among the bidding information stored in the storage unit is displayed for each of the prospective bidders, and in which the purchaser can select any of the prospective bidders as a successful bidder candidate; When receiving information that a successful bidder candidate has been selected on the selection screen, displaying a password entry screen for entering a successful bid password on the purchaser terminal, When receiving information that the successful bidder candidate has been selected on the selection screen, a successful bid password assigned individually to each of the bidding targets is issued, and the issued successful bid password is sent to the manager terminal out of the person in charge terminal and the manager terminal; If it is determined that the winning bid password entered on the password entry screen matches the issued winning bid password, the successful bidder candidate selected on the selection screen is determined to be the successful bidder for the bidding object.

[0008] In the present invention, bidding information including information on the bidding target to be ordered by the ordering company, the bidding deadline for the bidding target, and information on the prospective bidders permitted to participate in the bidding for the bidding target is transmitted from the ordering company's client terminal to the bid management device. The processing unit of the bid management device stores the received bidding information in a memory unit. The processing unit transmits the stored bidding information to the bidder terminals of the prospective bidders included in the bidding information. Then, bidding information including the bid price for the bidding target included in the transmitted bidding information and the names of the prospective bidders who have submitted their bid prices is transmitted from the bidder terminal to the bid management device. The processing unit of the bid management device stores the received bidding information in a memory unit in association with the already stored bidding information. This allows prospective bidders to submit bid prices for the bidding target to the ordering company without going through the ordering company's staff. As a result, it is possible to prevent staff from approaching prospective bidders to enter into a transaction involving a kickback.

[0009] Furthermore, in the present invention, the bid amounts and names of potential bidders included in the bidding information associated with bid information stored in the storage unit for which the bid closing date has not yet passed are prohibited from being displayed on the purchaser's terminal. Therefore, the purchaser's staff cannot learn the target bidders and their bid amounts from the purchaser's terminal. As a result, the staff can be prevented from proposing a deal involving a kickback to a potential bidder.

[0010] In the present invention, when the bid closing date has passed, a selection screen is displayed on the buyer terminal. The selection screen displays, for each potential bidder, the bid amount included in the bidding information associated with the bid information for which the bid closing date has passed, and is a screen for selecting one of the potential bidders as a successful bidder. When one of the multiple potential bidders displayed on the selection screen is selected as a successful bidder by operating the buyer terminal, information to that effect is transmitted from the buyer terminal to the bid management device. When the processing unit of the bid management device receives this information, it causes the buyer terminal to display a password entry screen for entering a successful bid password.

[0011] Furthermore, in the present invention, a winning bid password is issued for each bid target, and the issued winning bid password is sent to the manager's terminal, which is either the person in charge or the manager's terminal of the ordering company. If the processing unit determines that the winning bid password entered on the password entry screen matches the issued winning bid password, it determines the potential successful bidder selected on the selection screen as the successful bidder for the bid target. In other words, the person in charge of the ordering company is involved in the process of determining the successful bidder. This acts as a deterrent to the person in charge from proposing a deal involving a kickback to a prospective bidder.

[0012] As described above, the present invention allows prospective bidders to submit bids for a bid target to the purchaser without going through the purchaser's staff, and prohibits the display of bid amounts and prospective bidders on the purchaser's terminal until the bid closing date for the bid target has passed. This effectively prevents staff from proposing a deal involving a kickback to prospective bidders. Furthermore, the present invention involves the purchaser's responsible person in the process of determining the successful bidder, which acts as a deterrent to staff from proposing a deal involving a kickback to prospective bidders. This prevents the occurrence of situations that hinder fair order-taking between the purchaser and prospective bidders.

[0013] In this invention, a winning bid password sent to the manager's terminal is used to determine the successful bidder selected on the selection screen as the successful bidder for the bidding object. Therefore, instead of the manager entering the winning bid password on the password entry screen, the person in charge can enter the winning bid password provided by the manager. Therefore, even if the manager is unable to handle the task of determining the successful bidder, the person in charge can determine the successful bidder instead. This prevents the occurrence of situations that hinder fair order-taking operations and improves work efficiency. [Brief explanation of the drawings]

[0015] Hereinafter, a specific embodiment of a bid management device according to the present invention will be described with reference to the drawings. In this embodiment, the bid management device is a device for managing bidding conducted between contractors ordering construction work, civil engineering work, electrical work, etc., and bidders wishing to receive orders for the construction work. A management server 20 as the bid management device constitutes a bid management system 10 shown in FIG. 1.

[0016] The bid management system 10 includes, in addition to a management server 20, an administrator terminal 30, a manager terminal 40, a staff terminal 50, a bidder terminal 60, and a client terminal 70. The management server 20 and the administrator terminal 30 are devices operated by a management company that provides bid management services. The staff terminal 50 and the manager terminal 40 are devices of a contractor that orders construction work and uses the bid management service. The staff terminal 50 is a terminal operated by a staff member (e.g., a sales staff member) belonging to the contractor. The manager terminal 40 is a terminal separate from the staff terminal 50 and is operated by a staff member belonging to the contractor. The staff member has the authority to decide the successful bidder for the construction work that is the subject of bidding, and is, for example, the staff member's superior or an executive of the contractor. The bidder terminal 60 is a device of a contractor that wishes to bid for the construction work. The client terminal 70 is a device of a client that has requested the contractor to perform the construction work.

[0017] Each of the terminals 30, 40, 50, 60 is, for example, a tablet, a mobile device such as a smartphone, a notebook computer, or a desktop computer. In this embodiment, a plurality of manager terminals 40 and staff terminals 50 are provided. The management server 20, the administrator terminal 30, the manager terminal 40, the staff terminal 50, the bidder terminal 60, and the client terminal 70 are connected via a communication network 80. The communication network 80 is at least one of a wired network and a wireless network.

[0018] The management server 20 comprises a processing unit 21, a communication unit 22, and a memory unit 23. The processing unit 21 is mainly configured with a microcomputer and executes a program for bid management. The memory unit 23 is connected to the processing unit 21. The memory unit 23 stores program information for bid management, etc. For example, program information stored in a storage medium is installed in the memory unit 23. The storage medium is, for example, a USB memory or a CD-ROM. Furthermore, for example, program information transmitted via the communication network 80 is installed in the memory unit 23.

[0019] The communication unit 22 is connected to the processing unit 21 and the communication network 80, and transmits and receives data via the communication network 80. The communication unit 22 transmits data to other terminals in accordance with instructions from the processing unit 21. The communication unit 22 receives data transmitted from other terminals and transmits the data to the processing unit 21.

[0020] Like the management server 20, the manager terminal 30 includes a processing unit 31, a communication unit 32, and a memory unit 33. The manager terminal 30 includes an input unit 34 and a display unit 35. The input unit 34 is connected to the processing unit 31 and is a device that receives input from a manager (user) belonging to the management agent and transmits the received information to the processing unit 31. The input unit 34 is, for example, a touch panel, a touch display, hardware keys such as a keyboard, or a pointing device such as a mouse. The display unit 35 is connected to the processing unit 31 and is a device that outputs the processing results processed by the processing unit 31. The display unit 35 is, for example, a touch panel, a touch display, or a desktop display.

[0021] Like the manager terminal 30, the manager terminal 40 is equipped with a processing unit 41, a communication unit 42, a memory unit 43, an input unit 44, and a display unit 45. Like the manager terminal 30, the person in charge terminal 50 is equipped with a processing unit 51, a communication unit 52, a memory unit 53, an input unit 54, and a display unit 55. Like the manager terminal 30, the bidder terminal 60 is equipped with a processing unit 61, a communication unit 62, a memory unit 63, an input unit 64, and a display unit 65. Although not shown, the client terminal 70 also has a processing unit, a communication unit, a memory unit, an input unit, and a display unit.

[0022] An outline of the bid management service provided by the management server 20 will be explained below. This service is provided by the following processes: registration of ordering companies by the management company, registration of potential bidders by the management company, registration of potential bidders by the ordering company, registration of construction work (subject to bidding) by the ordering company, submission of bid information by potential bidders, and selection of a successful bidder by the ordering company. Each process will be explained below.

[0023] <Registration process of ordering companies by management companies> When the management server 20 is accessed from the administrator terminal 30, the processing unit 21 of the management server 20 displays the menu screen 100 shown in Fig. 2 on the display unit 35 of the administrator terminal 30. The menu screen 100 is provided with a Create Purchaser button 100a, a Purchaser Login button 100b, a Create Bidder button 100c, a Bidder Login button 100d, and a Client Login button 100e. Note that the menu screen 100 cannot be accessed from the manager terminal 40, the staff terminal 50, the bidder terminal 60, and the client terminal 70.

[0024] When the purchaser creation button 100a is selected (e.g., clicked or tapped) by operating the input unit 34 of the administrator terminal 30, the processing unit 21 of the management server 20 causes the display unit 35 of the administrator terminal 30 to display a purchaser registration screen 101 shown in FIG. 3 on the display unit 35 of the administrator terminal 30. The purchaser registration screen 101 has input fields for inputting purchaser information. Specifically, the purchaser registration screen 101 has a login ID (email address) input field 101a, a login password input field 101b, a purchaser name input field 101c, an address input field 101d, a telephone number input field 101e, a name input field 101f of a person in charge of the purchaser, an email address input field 101g for the person in charge's terminal 50, an email address input field 101h for the manager's terminal 40, and a registration button 101i. In this embodiment, the number of person in charge's name input fields 101f and email address input fields 101g is the same as the number of person in charge's terminals 50 constituting the bid management system 10 (two is shown as an example). In addition, the number of email address input fields 101h for the person in charge is also provided (two is shown as an example) equal to the number of person in charge terminals 40. In this embodiment, the login email address and login password are the same for each person in charge terminal 50 and each person in charge terminal 40.

[0025] Incidentally, although the number of each of the input fields 101f, 101g, and 101h is two in the example, the number is not limited to this, and may be three, or may be four or more. Also, the number of each of the input fields 101f, 101g, and 101h may be one.

[0026] Information is entered into each of the input fields 101a to 101h by operating the input unit 34 of the administrator terminal 30. In this embodiment, hereinafter, the name of the ordering company will be referred to as "XX Corporation." After information has been entered into each of the input fields 101a to 101h, when the register button 101i is selected by operating the input unit 34 of the administrator terminal 30, the ordering company information entered into each of the input fields 101a to 101h is sent from the administrator terminal 30 to the management server 20. The processing unit 21 of the management server 20 stores the received ordering company information in the memory unit 23. The memory unit 23 stores ordering company information for multiple ordering companies registered by the management company, and each ordering company information is stored in a database in association with the ID of each ordering company.

[0027] When the ordering company information is stored (registered) in the storage unit 23, the ordering company whose information is stored becomes able to use the bid management service.

[0028] <Registration process for potential bidders by the management company> When a bidder creation button 100c is selected on the menu screen 100 shown in Fig. 2 by operating the input unit 34 of the administrator terminal 30, the processing unit 21 of the management server 20 causes the display unit 35 of the administrator terminal 30 to display a bidder registration screen 102 shown in Fig. 4. The bidder registration screen 102 has input fields for inputting information about the prospective bidder. Specifically, the bidder registration screen 102 has a login ID input field 102a, a login password input field 102b, a bidder name input field 102c, an address input field 102d, a telephone number input field 102e, a name input field 102f of the person in charge belonging to the prospective bidder, an email address input field 102g for the prospective bidder's bidder terminal 60, an industry selection field 102h, and a registration button 102i.

[0029] The business type selection field 102h has check boxes for selecting the types of work that prospective bidders can accept. In Fig. 4, examples of work types are shown, such as foundations, foundation reinforcement, interior wallpaper, electrical work, and gas work. By checking the check boxes corresponding to the types of work that can be accepted, bidders can participate in bidding for the checked types of work.

[0030] Information is entered into each of the input fields 102a to 102g and the industry selection field 102h by operating the input unit 34 of the administrator terminal 30. In the example shown in FIG. 4, "Construction Company A" is entered as the name of the bidder. After the information is entered, when the register button 102i is selected by operating the input unit 34 of the administrator terminal 30, the bidder information entered into each of the input fields 102a to 102h and the industry selection field 102h is transmitted from the administrator terminal 30 to the management server 20. The processing unit 21 of the management server 20 stores the received bidder information in the memory unit 23. The memory unit 23 stores bidder information for multiple bidders registered by the administrator, and each bidder information is stored in a database in association with the ID of each bidder.

[0031] When a prospective bidder is stored (registered) in the storage unit 23, the stored prospective bidder becomes able to use the bid management service.

[0032] The processing unit 21 of the management server 20 issues a bidder code, which is an identification code associated with the stored bidder. The bidder code is information consisting of multiple character strings (see FIG. 18). The processing unit 21 stores the issued bidder code in the memory unit 23 in association with the bidder's ID and bidder information. When the processing unit 21 issues a bidder code, it may send the bidder code to the email address entered in the email address input field 102g of FIG. 4.

[0033] <Registration process for potential bidders by the ordering company> Hereinafter, the ordering company's person in charge terminal 50 and manager terminal 40 will be collectively referred to as the "orderer terminal." When the orderer terminal accesses the management server 20, the processing unit 21 of the management server 20 displays a login screen 103 shown in Fig. 5 on the display unit of the orderer terminal. The login screen 103 has a login ID input field 103a, a password input field 103b, and a login button 103c.

[0034] The input unit of the purchaser terminal is operated to input information into each input field 103a, 103b, and the login button 103c is selected. This causes a login request including the input information in each input field 103a, 103b to be sent from the purchaser terminal to the management server 20. When the processing unit 21 of the management server 20 receives the login request, it determines whether the login ID entered in the login ID input field 103a and the password entered in the password input field 103b match the login ID and password (see FIG. 3) of the purchaser stored in the storage unit 23. If the processing unit 21 determines that they match, it authenticates the login request from the purchaser terminal and displays the purchaser main screen 104 shown in FIG. 6 on the display unit of the purchaser terminal. The purchaser main screen 104 includes a site list button 104a, a bidder list button 104b, a past site button 104c, a settings button 104d, a logout button 104e, and a new bidder registration button 104f. The buyer's main screen 104 also displays the names of registered buyers and a registration information field 105. When the bidder list button 104b is selected, a display field for registered potential bidders is displayed in the registration information field 105, as shown in Fig. 6. On the other hand, when the site list button 104a is selected, a display field for registered site information is displayed in the registration information field 105, as shown in Fig. 7.

[0035] When the new bidder registration button 104f is selected by operating the input section of the purchaser terminal, a bidder registration request is sent from the purchaser terminal to the management server 20. When the processing section 21 of the management server 20 receives the bidder registration request, it causes the display section of the purchaser terminal to display a new bidder registration screen 106 shown in Fig. 8. The new bidder registration screen 106 has a bidder code input field 106a and a registration button 106b.

[0036] The ordering company (e.g., a person in charge) receives the bidder code from the prospective bidder who wishes to receive the order, and then operates the input unit of the ordering company's terminal to enter the bidder code into the bidder code input field 106a. The bidder code can be written, for example, on a paper document of the prospective bidder, and specifically, for example, on the business card of the prospective bidder's person in charge, as shown in FIG. 9. FIG. 9 shows an example in which the bidder code of construction company A is written as "FN74nunOPBR0nMXv1." By writing the bidder code on the business card, when the prospective bidder whose business card is written on the business card contacts the ordering company, it can be shown that the prospective bidder is a legitimate user of the bid management service that the ordering company also uses.

[0037] When the registration button 106b is selected, the bidder code entered in the bidder code input field 106a is transmitted from the purchaser terminal to the management server 20. The processing unit 21 of the management server 20 compares the received bidder code with the bidder codes stored in the memory unit 23. If the processing unit 21 determines that the received bidder code is among the stored bidder codes, it permits bidding between the bidder associated with the received bidder code and the purchaser that sent the bidder registration request. The processing unit 21 then displays, in the registration information field 105 of the display unit of the purchaser terminal, a bidder display field 107 that displays information about bidders whose bids have been permitted as registered bidders, as shown in FIG. 10 . FIG. 10 shows an example in which construction company A and construction company B are displayed as permitted bidders. The purchaser can register bidders as registered bidders by entering the bidder code without having to enter information such as the name and address of the bidder. This reduces the workload on the purchaser associated with registering bidders.

[0038] The bidder display field 107 has a details button 107a. When the details button 107a is selected, a request to display bidder information is sent from the buyer terminal to the management server 20. When the processing unit 21 of the management server 20 receives the request, it causes the display unit of the buyer terminal to display the bidder information stored in the memory unit 23. This allows the buyer to check the bidder information via the registration information field 105.

[0039] <Construction work registration processing by contractors> The client main screen 104 shown in Fig. 7 has a site registration button 104g. When the site registration button 104g is selected, a site registration request is sent from the client terminal to the management server 20. When the processing unit 21 of the management server 20 receives the request, it displays a new site registration field 109 on the display unit of the client terminal, as shown in Fig. 11. The new site registration field 109 has a site name input field 109a for the construction work to be bid on, a site address input field 109b, a construction start date input field 109c for the construction work, a client login ID input field 109d, a client login password input field 109e, and a site registration button 109f.

[0040] After inputting information into each of the input fields 109a to 109e by operating the input unit of the client terminal, when the site registration button 109f is selected, site information including the input information into each of the input fields 109a to 109e is transmitted from the client terminal to the management server 20. When the processing unit 21 of the management server 20 receives the site information, it stores the received site information in the memory unit 23. Furthermore, the processing unit 21 displays the site information stored in the memory unit 23 on the display unit of the client terminal in response to a request from the processing unit of the client terminal. This allows the client to check the site information via the individual site information display field 110 shown in FIG. 12. The individual site information display field 110 is provided with a bid information button 110a, a progress management button 110b, and a construction completion button 110c.

[0041] When the bid information button 110a is selected by operating the input unit of the purchaser terminal, a bid registration request is sent from the purchaser terminal to the management server 20. When the processing unit 21 of the management server 20 receives the bid registration request, it causes the display unit of the purchaser terminal to display a first bid registration display field 111 shown in FIG. 13. The first bid registration display field 111 is provided with display fields for the site name, site address, and construction start date, which are information entered on the screen shown in FIG. 12 and included in the site information stored in the memory unit 23, an industry selection field 111a, and an industry registration button 111b. The industry selection field 111a is the same as the industry selection field 102h shown in FIG. 4.

[0042] The content of work is checked in the industry selection field 111a by operating the input section of the purchaser terminal. In the example shown in FIG. 13, foundation reinforcement and foundation are checked as the content of work. When the industry registration button 111b is selected in a checked state, an industry registration request is sent from the purchaser terminal to the management server 20. When the processing unit 21 of the management server 20 receives the industry registration request, it displays the second bid registration display field 112 shown in FIG. 14 on the display section of the purchaser terminal. The second bid registration display field 112 is displayed for each industry content selected in FIG. 13. FIG. 14 shows an example of the second bid registration display field 112 corresponding to foundation reinforcement.

[0043] The second bid registration display field 112 includes an authorized bidder input field 112a for inputting the names of bidders authorized to participate in the bid, a comment input field 112b for entering comments about the construction work, and a file selection button 112c for attaching data files such as drawings related to the construction work. The second bid registration display field 112 also includes an input field 112d for the desired bid price of the construction work being bid on, a selection field 112e for selecting whether the amount entered in the input field 112d is tax-inclusive or tax-exclusive, an input field 112f for the construction work bid closing date, an input field 112g for the bid results publication date, and a bid registration button 112h. The authorized bidder input field 112a automatically populates the checkboxes with the names of bidders corresponding to the selected business type. The ordering company checks the checkboxes of bidders authorized to participate in the bid from among those capable of accepting the selected business type. The ordering company can also delete bidders automatically entered in the authorized bidder input field 112a. Furthermore, input into the input field 112d for the desired bid price is optional.

[0044] After information is entered in each of the input fields 112a to 112g, when the bid registration button 112h is selected, bid information including the input information in each of the input fields 112a to 112g is transmitted from the purchaser terminal to the management server 20. When the processing unit 21 of the management server 20 receives the bid information, it stores the received bid information in the memory unit 23. Furthermore, the management server 20 displays a bid opening information field 113 on the display unit of the purchaser terminal, as shown in FIG. 14. The bid opening information field 113 has a registered site information field 114 that displays each registered bid information. The registered site information field 114 has a bid details button 114a that displays details of the bid information, and a bid cancel button 114b.

[0045] If the processing unit 21 determines that the bid cancellation button 114b has been selected before the bidding deadline has passed, it performs a process to cancel the bidding for the construction work for which cancellation has been selected. This process includes a process to delete the relevant bidding information from the bid opening information field 113 and a process to send information that the bidding has been canceled to the bidder terminal 60 of the prospective bidder entered in the participation permission input field 112a.

[0046] After receiving and storing the bid information, the processing unit 21 may send information indicating that the bid information has been registered to the purchaser terminal by email. In this case, the email to be sent may include URL information leading to the screen shown in FIG. 15.

[0047] An example will be described in which the bid details button 114a for foundation reinforcement shown in FIG. 15 is selected. In this case, the processing unit 21 of the management server 20 causes the display unit of the client terminal to display the bid information details field 115 shown in FIG. 16. The bid information details field 115 has a first display field 115a, a second display field 115b, and a third display field 115c. The first display field 115a displays the work content, site name, site address, construction start date, bid closing date, and bid result publication date. The second display field 115b displays the bidders who have been permitted to participate in the bid, the information entered in the comment input field 112b in FIG. 14, file information attached using the file selection button 112c, and the desired bid price.

[0048] The third display field 115c displays the "number of bidders," the "number of bidders who have submitted bids," and the "number of bidders waiting for bids." The "number of bidders" is the number of bidders who have been permitted to participate in the bidding, and is the number of contractors displayed in the accepted contractors field in the first display field 115a. The "number of bidders who have submitted bids" is the number of bidders who have been permitted to participate but have already submitted bidding information, as described below. The "number of bidders waiting for bids" is the number of bidders who have been permitted to participate but have not yet submitted bidding information.

[0049] The processing unit 21 also transmits the registered bidding information and an email informing the bidder that bidding has begun to the bidder terminal 60 of the prospective bidder entered in the participation permitted bidder input field 112a in Fig. 14. As a result, the registered bidding information is displayed in the registration information field 202 in Fig. 19, which will be described later.

[0050] <Submission of bid information by prospective bidders> When a bidder terminal 60 accesses the management server 20, the processing unit 21 of the management server 20 displays a login screen 200 shown in Fig. 17 on the display unit 65 of the bidder terminal 60. The login screen 200 has a login ID input field 200a, a password input field 200b, and a login button 200c.

[0051] The bidder operates the input unit 64 of the bidder terminal 60 to enter information into each input field 200a, 200b, and selects the login button 200c. This causes a login request including the information in each input field 200a, 200b to be sent from the bidder terminal 60 to the management server 20. When the processing unit 21 of the management server 20 receives the login request, it determines whether the set of the login ID entered in the login ID input field 200a and the password entered in the password input field 200b (see FIG. 4) matches the set of the login ID and password of the prospective bidder stored in the memory unit 23. If the processing unit 21 determines that they match, it authenticates the login request from the bidder terminal 60 and causes the display unit 65 of the bidder terminal 60 to display a bidder main screen 201 shown in FIG. 18. The bidder main screen 201 has a site list button 201a, a bid list button 201b, a past site button 201c, a settings button 201d, a logout button 201e, and a new site registration button 201f. The bidder main screen 201 also displays a display field for the name and bidder code of the logged-in bidder, as well as a registration information field 202.

[0052] When the site list button 201a is selected, a display field for site information received from the ordering company is displayed in the registered information field 202, as shown in Fig. 18. On the other hand, when the bid list button 201b is selected, a display field for bidding information registered by the ordering company is displayed in the registered information field 202, as shown in Fig. 19. The registered information field 202 is provided with an individual bid information display field 204 for each business type. The individual bid information display field 204 is provided with a display field for registered bidding information including the ordering company's name, work content, site name, bid closing date, and bid result publication date for each construction job to be bid, as well as a bid information registration button 204a.

[0053] When the bid information registration button 204a is selected by operating the input unit 64 of the bidder terminal 60, a bid information registration request is sent from the bidder terminal 60 to the management server 20. When the processing unit 21 of the management server 20 receives the bid information registration request, it causes the bid information input field 205 shown in FIG. 20 to be displayed on the display unit 65 of the bidder terminal 60. The bid information input field 205 is provided with a bid amount input field 205a, a file attachment button 205b, a comment input field 205c, and a send button 205d. The bid amount submitted by the prospective bidder is entered in the bid amount input field 205a. The file attachment button 205b is a button for attaching a data file such as a drawing related to the construction details.

[0054] After inputting information into each of the input fields 205a to 205c, when the send button 205d is selected, bidding information including the information input into the bidding information input field 205 and the names of the companies wishing to participate is transmitted from the bidder terminal 60 to the management server 20. When the processing unit 21 of the management server 20 receives the bidding information, it stores the received bidding information in the memory unit 23 in association with the bidding information already stored. Furthermore, as shown in Fig. 21 , the processing unit 21 displays a bidding information display field 206 showing the bidding information on the display unit 65 of the bidder terminal 60, and sends an email to the buyer terminal informing them that the bidding information has been transmitted.

[0055] As shown in FIG. 16, the processing unit 21 prohibits the display of the purchaser terminal of the bid amount and the name of the prospective bidder included in the bidding information associated with the bidding information stored in the memory unit 23 for which the bidding deadline has not yet passed. For example, the processing unit 21 prohibits the display of the bidding information on the display by prohibiting the transmission of the bidding information to the purchaser terminal. By prohibiting the display, the purchaser's staff member cannot learn the prospective bidders and their bid amounts from the purchaser terminal. As a result, it is possible to prevent the staff member from proposing a deal involving a kickback to the prospective bidder.

[0056] The processing unit displays the number of prospective bidders included in the bidding information associated with the bidding information for which the bidding deadline has not yet passed among the bidding information stored in the storage unit 23 as the number of "bids completed" in the third display field 115c. This allows the user to know before the bidding deadline whether the number of prospective bidders is low or zero, and provides information for considering whether to cancel the bidding, etc.

[0057] <Process for determining successful bidder by the ordering company> When the processing unit 21 of the management server 20 receives the bid information, it displays a bid opening information field 113 and a bid awaiting successful bid information display field 116 on the display unit of the purchaser terminal, as shown in FIG. 22. The bid opening information field 113 is a field that displays, among the registered bid information, bid information for which the bid closing date has not yet passed. The bid awaiting successful bid information display field 116 is a field that displays, among the registered bid information, bid information for which the bid closing date has passed. The bid opening information field 113 is provided with a bid details button 114a and a bid cancel button 114b that instructs the cancellation of the bid. The information display field 116 is provided with a bid details button 116a.

[0058] When the processing unit 21 of the management server 20 determines that the bid details button 116a in the successful bid information display field 116 has been selected, it causes a selection screen 117 for selecting a potential bidder as a successful bidder to be displayed on the display unit of the purchaser terminal, as shown in Figure 23. Here, the bids can be displayed in ascending or descending order of bid price. The selection screen 117 has a details confirmation button 117a and a provisional successful bid button 117b.

[0059] When the "Tentatively Successful Bid" button 117b corresponding to the bidder to be accepted is selected, a successful bid request is sent from the buyer terminal to the management server 20. The processing unit 21 of the management server 20 causes the display unit of the buyer terminal to display the successful bid determination screen shown in Fig. 24. The successful bid determination screen has a password input field 118a and a successful bid determination button 118b.

[0060] Furthermore, when the processing unit 21 receives a winning bid request, it issues a winning bid password and sends an email containing the issued winning bid password to each of the client's terminals, not to each of the staff member terminals 50, but to each of the manager terminals 40 with the manager's email address registered in Figure 3. The email includes information about the site name, business type, address, bid amount submitted by the potential successful bidder, and the winning bid password for the construction work being bid on. The winning bid password is a password consisting of multiple character strings. The winning bid password is a password assigned individually to each construction work being bid on. For this reason, using Figure 22 as an example, the winning bid password for the foundation reinforcement construction work is different from the winning bid password for the foundation construction work. The winning bid password may, for example, be a one-time password that becomes invalid after a certain period of time has passed since it was issued.

[0061] When the successful bid decision button 118b is selected, the entered successful bid password is sent from the purchaser terminal to the management server 20. The processing unit of the management server 20 determines whether the received successful bid password matches the previously issued successful bid password. If the processing unit 21 determines that they do not match, it displays a message on the display unit of the purchaser terminal recommending that the successful bid password be entered again. On the other hand, if the processing unit 21 determines that they match, it displays a successful bid completion screen shown in FIG. 25 on the display unit of the purchaser terminal that selected the successful bid decision button 118b. The successful bid completion screen has a site information display field 119, a successful bidder information display field 120, and a bidding condition display field 121.

[0062] There are two main processes for determining the successful bidder:

[0063] The first pattern is when the person in charge decides to make a successful bid. The person in charge operates the input unit 44 of the person in charge terminal 40 to select the provisionally successful bid button 117b. In this case, the person in charge enters the successful bid password in the password input field 118a shown in FIG. 24 and selects the successful bid button 118b.

[0064] The second pattern is when the person in charge decides to make a successful bid. The person in charge operates the input unit 54 of the person in charge terminal 50 to select the provisionally successful bid button 117b. In this case, a successful bid password is sent to the manager terminal 40. The person in charge is informed of the successful bid password by the manager. The person in charge enters the successful bid password in the password input field 118a shown in FIG. 24 and selects the successful bid button 118b.

[0065] Next, the procedure of the bid management process executed by the processing unit 21 of the management server will be described with reference to FIG.

[0066] In step S10, the bidding information is received from the purchaser terminal, and the received bidding information is stored in the storage unit 23.

[0067] In step S11, bidding information is received from the bidder terminal 60, and the received bidding information is stored in the storage unit 23.

[0068] In step S12, a process is performed to prohibit the bid amount and the name of the bidder contained in the bidding information associated with the bidding information stored in the memory unit 23 for which the bidding deadline has not yet passed from being displayed on the purchaser's terminal.

[0069] In step S13, it is determined whether or not any of the bid information stored in the storage unit 23 is bid for which the bid deadline has passed.

[0070] If it is determined in step S13 that there is no bidding information for which the bidding deadline has passed, the process proceeds to step S14, where it is determined whether or not the bidding cancellation button 114b has been selected to instruct bidding cancellation. If it is determined that bidding cancellation has been instructed, this series of processes ends.

[0071] If it is determined in step S13 that there is bid information for which the bid deadline has passed, the process proceeds to step S15, where processing is performed to permit the bid amount and the name of the prospective bidder to be displayed on the buyer terminal.

[0072] In step S16, a process is performed to display the selection screen 117 shown in FIG. 23 on the display unit of the orderer terminal.

[0073] In step S17, it is determined whether or not the bid provisional decision button 117b in FIG. 23 has been selected and a bid request has been received from the purchaser terminal.

[0074] If it is determined in step S17 that a successful bid request has been received, the process proceeds to step S18, where a password entry field 118a shown in Fig. 24 for entering a successful bid password is displayed on the display unit of the buyer terminal. In addition, a successful bid password assigned individually to each bid item is issued, and the issued successful bid password is sent only to the manager terminal out of the staff terminal and the manager terminal.

[0075] In step S19, if it is determined that the winning bid password entered in password input field 118a matches the issued winning bid password, the process proceeds to step S20, where the process determines the potential winning bidder selected on selection screen 117 as the winning bidder for the bidding object.

[0076] In step S21, a process is performed in which information indicating that the bidder has been selected as the successful bidder is sent to the bidder terminal 60 of the bidder who has been selected as the successful bidder. Also, the processing unit 21 causes the registration information field 202 of the bidder terminal 60 of the successful bidder to display a display field 208 for the construction work for which the bid has been won, as shown in Fig. 27. Note that the processing unit 21 will not disclose the information on the successful bid results shown in Fig. 25 to bidders other than the successful bidder among the bidders who have submitted their bidding information until the bid result disclosure date has passed.

[0077] After the successful bid, the successful bidder and the contractor can use the construction work progress management service in the bid management service. The successful bidder can use the progress management function by selecting the progress management button 208a in the display field 208, as shown in FIG. 27. The display field 208 also has a button 208b for confirming the details of the bid information. The contractor can use the progress management function by selecting the progress management button 110b in the individual site information display field 110, as shown in FIG. 12. The progress status can also be disclosed to the client via the client terminal 70. In this case, the client logs in to the bid management service using the client login ID and client login password provided by the contractor. In this case, the client login ID is the input information in the client login ID input field 109d in FIG. 11, and the client login password is the input information in the client login password input field 109e.

[0078] In the embodiment described above, prospective bidders can submit bids for a bid target to the purchaser without going through the purchaser's staff, and the bid amount and prospective bidders are prohibited from being displayed on the purchaser's terminal until the bid deadline for the bid target has passed. This effectively prevents staff from proposing a deal involving a kickback to prospective bidders. Furthermore, since the purchaser's responsible person is involved in the process of determining the successful bidder, this acts as a deterrent to staff from proposing a deal involving a kickback to prospective bidders. This prevents the occurrence of situations that hinder fair order-taking between the purchaser and prospective bidders.

[0079] Furthermore, a winning bid password sent to the manager's terminal 40 is used to determine the successful bidder selected on the selection screen 117 as the successful bidder for the bidding target. Therefore, instead of the manager entering the winning bid password in the password input field 118a, the person in charge can enter the winning bid password provided by the manager. Therefore, even if the manager is unable to handle the task of determining the successful bidder, the person in charge can determine the successful bidder instead. This makes it possible to improve business efficiency while preventing situations from occurring that hinder fair order-taking operations.

[0080] The above embodiment may be modified as follows.

[0081] The bidding object managed by the bid management process is not limited to construction work, but may also be real estate such as an apartment building, for example. [Explanation of symbols]
