[0023] (3. Functional configuration of the management system of the embodiment) The functional configuration of management system 1 will be explained using Figure 3.

[0024] Functionally, the sales server 100 comprises a reporting unit 101, a receiving unit 102, a payment processing unit 103, a second registration unit 104, and a presentation unit 105. In this embodiment, the CPU 11 and the communication device 16 function as the reporting unit 101, the receiving unit 102, and the presentation unit 105, while the CPU 11 functions as the payment processing unit 103 and the second registration unit 104.

[0025] Functionally, the management server 200 comprises a determination unit 201, an acquisition unit 202, a first registration unit 203, and a notification unit 204. In this embodiment, the CPU 11 and the communication device 16 function as the determination unit 201, the acquisition unit 202, and the notification unit 204, while the CPU 11 functions as the first registration unit 203.

[0026] Figure 4 shows an example of a sales page provided from the sales server 100 to the shopper terminal 300. Sales page 500-1 in Figure 4 is a page for seller V1 to sell a specific product, therapeutic dog food P1. Sales page 500-1 includes an image 501 of therapeutic dog food P1, a button 503 for adding the product to the electronic cart 502, and a button 504 for proceeding with the purchase process. Note that sales page 500-1 may include only one of buttons 503 or 504. Sales page 500-1 in Figure 4 shows the state after therapeutic dog food P1 has been added to the electronic cart 502. The functions of the sales server 100 and the management server 200 will be explained below using the case where shopper S1 attempts to purchase therapeutic dog food P1 from seller V1 for the first time as an example.

[0027] If a specific product is included in the items that a shopper has placed into an electronic cart via a shopper terminal 300, the reporting unit 101 of the sales server 100 reports to the management server 200 product identification information to identify the specific product placed into the electronic cart, seller identification information to identify the seller who is the supplier of the specific product placed into the electronic cart, and terminal identification information to identify the shopper terminal 300.

[0028] Product identification information is identification information used to identify products in electronic marketplaces, such as the JAN (Japanese Article Number) code.

[0029] Seller identification information is information used to identify sellers who sell goods in the electronic marketplace, and is managed by the sales server 100, such as seller name, address, telephone number, and email address.

[0030] Terminal identification information is information used to identify the shopper terminal 300 used by shoppers in the electronic marketplace. Terminal identification information includes, for example, MAC address, IP address, session ID, etc.

[0031] For example, the sales server 100 has a list (hereinafter referred to as the "specific product list") that contains product identification information for specific products handled in the electronic market. For example, the recording medium 14 of the sales server 100 stores the specific product list. The reporting unit 101 refers to the specific product list and determines whether or not a specific product is included in the products that shopper S1 has placed into the electronic cart via the shopper terminal 300. The reporting unit 101 determines that a specific product is included in the products placed into the electronic cart if the product identification information of the products placed into the electronic cart matches any of the product identification information in the specific product list. In the following, it is assumed that the specific product list includes the product identification information "xxxxxxxxxxxx" for therapeutic food P1.

[0032] Here, the timing at which the reporting unit 101 determines whether or not a specific product is included in the products added to the electronic cart (hereinafter referred to as the "determination timing") is arbitrarily determined by the administrator of the sales server 100. For example, the determination timing may be when a product is added to the electronic cart 502 (i.e., when button 503 is selected), when a predetermined amount of time has elapsed since a product was added to the electronic cart 502, or when an instruction to proceed with the purchase procedure is received from the shopper (i.e., when button 504 is selected). In the following, it will be assumed that the determination timing is set to when an instruction to proceed with the purchase procedure is received from the shopper.

[0033] When the timing for a decision arrives, the reporting unit 101, referring to the specific product list, determines that the specific product, therapeutic food P1, is included in the electronic cart of sales page 500-1 in Figure 4. It then provides the shopper terminal 300 of shopper S1 with the transition notification page 500-2 shown in Figure 5. The transition notification page 500-2 is a page for notifying the shopper of transitioning to a site managed by the management server 200, and includes a button 505 for transitioning to the site managed by the management server 200. After a predetermined time has elapsed since providing the transition notification page 500-2, or after the button 505 is selected, the reporting unit 101 reports to the management server 200 the product identification information "xxxxxxxxxxxxx" for therapeutic food P1, the seller identification information "V1" for seller V1, the seller of therapeutic food P1, and the terminal identification information "yyyyy" for identifying the shopper terminal 300 of shopper S1.

[0034] The determination unit 201 of the management server 200 determines whether the seller identified by the reported seller identification information is able to sell the specific product identified by the reported product identification information.

[0035] For example, the management server 200 has a list (hereinafter referred to as the "seller list") which includes seller identification information of sellers authorized to sell specific products in the electronic marketplace, and product identification information of specific products authorized to be sold by those sellers. The determination unit 201 refers to the seller list and determines whether the seller identified by the seller identification information reported from the sales server 100 is authorized to sell the specific product identified by the product identification information reported from the sales server 100. In the following, it is assumed that the seller list includes the seller identification information "V1" of seller V1 and the product identification information "xxxxxxxxxxxxx" of therapeutic food P1, linked together. The determination unit 201 refers to the seller list and determines that seller V1 is authorized to sell therapeutic food P1.

[0036] If the determined result indicates that the item is available for sale, the acquisition unit 202 of the management server 200 acquires purchase information, including buyer identification information for identifying the shopper, by having the shopper terminal 300, which is identified by the reported terminal identification information, input the purchase information.

[0037] Buyer identification information refers to information used to identify a shopper who intends to purchase a specific product, and includes information such as name, email address, and phone number.

[0038] Purchase information refers to information indicating the purchase details, including purchaser identification information, and prescriber identification information to identify the veterinarian or hospital that prescribed the therapeutic diet to the shopper. Prescriber identification information is identification information for identifying the prescriber, such as the veterinarian's name and the name of the hospital. In addition, purchase information includes information about the pet to which the prescription was given.

[0039] For example, if the acquisition unit 202 determines that the item is available for sale by the determination unit 201, it provides a purchase information input page to the shopper terminal 300 with terminal identification information "yyyyy" for entering purchase information.

[0040] Figure 6 shows an example of a purchase information input page. The purchase information input page 600 in Figure 6 includes several fields 601 for entering purchaser identification information, a field 602 for entering the pet's name, a field 603 for entering prescriber identification information, and a button 604 that instructs the user to register the information entered in fields 601 to 603.

[0041] For example, when button 604 is selected on the purchase information input page 600 in Figure 6, the acquisition unit 202 acquires the purchaser identification information as name "aaa aaa", email address "bbb@bbb.com", and telephone number "ccc-ccc-ccc", as well as the prescriber identification information as "eee Hospital", and the pet name "dd" as other purchase information.

[0042] When purchase information is acquired, the first registration unit 203 of the management server 200 registers the reported seller identification information, the reported product identification information, and the acquired purchase information in association.

[0043] For example, the first registration unit 203 associates the seller identification information "V1" of seller V1 with the product identification information "xxxxxxxxxxxxx" of therapeutic food P1, and the purchase information, name "aaa aaa", email address "bbb@bbb.com", telephone number "ccc-ccc-ccc", pet name "dd", and "eee Hospital", and registers it as management information. The management information is stored on the recording medium 14 of the management server 200, or in a database on another server connected to the management server 200.

[0044] Here, the first registration unit 203 registers the seller identification information, product identification information, and purchase information, linking them with the information available for sale.

[0045] Sales availability information refers to information indicating that the seller identified by the reported seller identification information has been determined by the determination unit 201 to be available to sell a specific product identified by the reported product identification information. When the determination unit 201 determines that the product is available to sell, the acquisition unit 202 acquires purchase information. Therefore, the date and time when the determination unit 201 determined that the product was available to sell is set as the date and time when the acquisition unit 202 acquired the purchase information. Sales availability information includes date and time information indicating the date and time when the purchase information was acquired.

[0046] Figure 7 shows an example of management information. The management information 700 in Figure 7 includes seller identification information, product identification information, purchase information, and saleability information, all linked together. The first record in the management information 700 indicates that the manufacturer has authorized the sale of therapeutic food P1, product identification information "xxxxxxxxxxxxx", by seller V1, whose seller identification information is "V1", the purchaser of the product is named "aaa aaa", whose email address is "bbb@bbb.com", whose phone number is "ccc-ccc-ccc", whose pet's name is "dd", prescribed by "eee Hospital", and that on "December 12, 2024, 10:00:00", the determination unit 201 determined that seller V1 was eligible to sell therapeutic food P1.

[0047] If the result of the determination indicates that the product is available for sale, the notification unit 204 of the management server 200 notifies the sales server 100 that the seller identified by the reported seller identification information is available for sale for the specific product identified by the reported product identification information. Here, the notification unit 204 notifies the result that the product is available for sale, including date and time information indicating the date and time when the purchase information was acquired.

[0048] For example, the notification unit 204 notifies the sales server 100 that seller V1, identified by seller identification information "V1", is able to sell therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx", and also notifies the sales availability information "December 12, 2024, 10:00:00".

[0049] On the other hand, if the determined result indicates that the product is unsaleable, the notification unit 204 notifies the sales server 100 that the seller identified by the reported seller identification information is unsaleable for the specific product identified by the reported product identification information.

[0050] For example, suppose the seller list does not include a corresponding seller identification information "V1" for seller V1 and product identification information "xxxxxxxxxxxxx" for therapeutic food P1. In this case, the determination unit 201 refers to the seller list and determines that seller V1 is unable to sell therapeutic food P1. The notification unit 204 then notifies the sales server 100 that seller V1, identified by seller identification information "V1", is unable to sell therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx".

[0051] The reception unit 102 of the sales server 100 receives the results notified from the management server 200.

[0052] For example, the reception unit 102 receives from the management server 200 information that seller V1, identified by seller identification information "V1", is able to sell therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx", and sales availability information "December 12, 2024, 10:00:00". Alternatively, the reception unit 102 receives from the management server 200 to the sales server 100 information that seller V1, identified by seller identification information "V1", is unable to sell therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx".

[0053] If the payment processing unit 103 of the sales server 100 indicates that the item is available for sale, it executes the payment processing for the purchase of the item placed in the electronic cart.

[0054] For example, if the reception unit 102 receives information that seller V1, identified by seller identification information "V1", is able to sell therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx", then the payment processing unit 103 provides the electronic cart page shown in Figure 8, which displays the details of the products placed in the electronic cart. The payment processing unit 103 then proceeds with the payment processing according to the instructions from shopper S1.

[0055] When the payment processing is completed, the second registration unit 104 of the sales server 100 registers the purchase history of the specific product for which the payment processing has been completed, along with the available sales information included in the received results.

[0056] For example, when the payment processing for therapeutic food P1 for shopper S1 is completed, the second registration unit 104 associates the purchase history information indicating that shopper S1 purchased therapeutic food P1 from seller V1 with the availability information "December 12, 2024, 10:00:00" and registers it as sales information. The sales information is stored on the recording medium 14 of the sales server 100, or in a database on another server connected to the sales server 100.

[0057] Figure 9 shows an example of sales information. The sales information 800 in Figure 9 includes shopper identification information for identifying shoppers in the electronic marketplace, seller identification information, product identification information, purchase date and time information, and availability information, all linked together. The first record in the sales information 800 indicates that shopper S1, with shopper identification information "S1", purchased therapeutic food P1, with product identification information "xxxxxxxxxxxxx", from seller V1, with seller identification information "V1", and that the payment process was completed on December 12, 2024, at 10:05:00. The sales related to this payment process are indicated by the availability information "December 12, 2024, at 10:00:00", when the management server 200 determined that seller V1 had made therapeutic food P1 available for sale.

[0058] If the display unit 105 of the sales server 100 indicates that the received result is unsaleable, it prompts the shopper terminal 300 to remove the specific product that has been placed in the electronic cart.

[0059] For example, if the reception unit 102 receives information from the management server 200 that seller V1, identified by seller identification information "V1", is unable to sell therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx", the presentation unit 105 will provide the shopper terminal 300 of shopper S1 with the removal notification page 500-4 shown in Figure 10. The removal notification page 500-4 includes a message 506 prompting the shopper to remove therapeutic food P1 from the electronic cart.

[0060] Next, we will explain the functions of each part when a shopper purchases the same product again.

[0061] The reporting unit 101 of the sales server 100, upon referring to the purchase history, determines that a specific product added to the electronic cart was previously purchased from the seller of that specific product. In doing so, it reports the sales-available information registered in association with the purchase history of the specific product that was determined to have been purchased, along with product identification information, seller identification information, and terminal identification information, to the management server 200.

[0062] For example, if shopper S1 places therapeutic food P1 sold by seller V1 into their electronic cart, the reporting unit 101 refers to the purchase history information included in the sales information to determine whether shopper S1 has previously purchased therapeutic food P1 sold by seller V1. If the reporting unit 101 determines that shopper S1 has previously purchased therapeutic food P1 sold by seller V1, it reports the product identification information of therapeutic food P1 "xxxxxxxxxxxxx", the seller identification information of seller V1, who is the seller of therapeutic food P1, "V1", the terminal identification information "yyyyy" to identify shopper S1's shopper terminal 300, and the availability information "December 12, 2024, 10:00:00 AM" to the management server 200.

[0063] The determination unit 201 of the management server 200 determines that if the period from the date and time indicated by the date and time information included in the reported availability information to the present is within a predetermined period, the seller identified by the seller identification information reported together with the availability information is available to sell the specific product identified by the product identification information reported together with the availability information.

[0064] The predetermined period indicates the expiration date of the result that the determination unit 201 has determined to be available for sale, and is set arbitrarily by the administrator of the management server 200. In the following, it will be assumed that the predetermined period is set to "6 months".

[0065] For example, the determination unit 201 determines that if the period from the date and time information "December 12, 2024, 10:00:00" included in the availability information to the present is within a predetermined period of "6 months", then the seller V1 identified by the seller identification information "V1" reported together with the availability information is available to sell the therapeutic food P1 identified by the product identification information "xxxxxxxxxxxxx" reported together with the availability information.

[0066] The management server 200 then omits the acquisition of purchase information by the acquisition unit 202.

[0067] For example, the acquisition unit 202 does not provide a purchase information input page, and the notification unit 204 notifies the sales server 100 that seller V1, identified by seller identification information "V1", is able to sell therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx", and also notifies the sales availability information "December 12, 2024, 10:00:00".

[0068] On the other hand, if the period from the date and time information "December 12, 2024, 10:00:00" included in the available sales information to the present exceeds the predetermined period of "6 months", the acquisition unit 202 provides the shopper terminal 300 of shopper S1 with a purchase information input page and acquires new purchase information.

[0069] (4. Sales processing by the sales server in the embodiment) The sales process for a specific product executed by the sales server 100 in this embodiment will be explained using Figure 11. For example, when the decision timing arrives, the sales server 100 starts the sales process for a specific product shown in Figure 11.

[0070] The reporting unit 101 determines whether the items added to the electronic cart by the shopper include a specific product (step S101). If the reporting unit 101 determines that the items added to the electronic cart include a specific product (step S101; YES), it refers to the purchase history to determine whether the shopper had previously purchased the specific product added to the electronic cart from the seller of that specific product (step S102). On the other hand, if the reporting unit 101 determines that the items added to the electronic cart do not include a specific product (step S101; NO), the sales server 100 terminates the specific product sales process shown in Figure 11.

[0071] For example, if the reporting unit 101 refers to the specific product list and determines that the items added to the electronic cart by shopper S1 via the shopper terminal 300 include the specific product, therapeutic food P1, it refers to the purchase history information included in the sales information and determines whether shopper S1 has previously purchased therapeutic food P1 sold by seller V1. On the other hand, if the reporting unit 101 refers to the specific product list and determines that the items added to the electronic cart by shopper S1 via the shopper terminal 300 do not include the specific product, the sales server 100 terminates the sales process shown in Figure 11.

[0072] In step S102, the reporting unit 101, by referring to the purchase history, determines that the shopper had previously purchased a specific product added to the electronic cart from the seller of that product (step S102; YES), and provides the shopper terminal 300 with a transition notification page to notify it of the transition to a site managed by the management server 200 (step S103). The reporting unit 101 then reports to the management server 200 the salesable information registered in association with the purchase history of the specific product that it determined had been purchased, along with product identification information to identify the specific product added to the electronic cart, seller identification information to identify the seller of the specific product added to the electronic cart, and terminal identification information to identify the shopper terminal 300 (step S104). Meanwhile, if the reporting unit 101, after referring to the purchase history, determines that the shopper has not previously purchased a specific product added to the electronic cart from the seller of that product (step S102; NO), it provides the shopper terminal 300 with a transition notification page to notify it that it will transition to a site managed by the management server 200 (step S105). The reporting unit 101 then reports to the management server 200 product identification information to identify the specific product added to the electronic cart, seller identification information to identify the seller of the specific product added to the electronic cart, and terminal identification information to identify the shopper terminal 300 (step S106).

[0073] For example, if the reporting unit 101 refers to the purchase history information included in the sales information and determines that shopper S1 has previously purchased therapeutic food P1 sold by seller V1, it provides shopper S1's shopper terminal 300 with the transition notification page 500-2 shown in Figure 5, and reports to the management server 200 the product identification information of therapeutic food P1 "xxxxxxxxxxxxx", the seller identification information of seller V1, who is the seller of therapeutic food P1, "V1", the terminal identification information "yyyyy" to identify shopper S1's shopper terminal 300, and the availability information "December 12, 2024, 10:00:00". Meanwhile, the reporting unit 101, by referring to the purchase history information included in the sales information, determines that shopper S1 has not previously purchased therapeutic food P1 sold by seller V1. In doing so, it provides shopper S1's shopper terminal 300 with the transition notification page 500-2 shown in Figure 5, and reports to the management server 200 the product identification information of therapeutic food P1 "xxxxxxxxxxxxx", the seller identification information of seller V1, who is the seller of therapeutic food P1, "V1", and the terminal identification information "yyyyy" to identify shopper S1's shopper terminal 300.

[0074] The receiving unit 102 determines whether or not it has received the result notified by the management server 200 (step S107). If the receiving unit 102 determines that it has received the result notified by the management server 200 (step S107; YES), it determines whether or not the received result indicates that the product is available for sale (step S108). On the other hand, if the receiving unit 102 determines that it has not received the result notified by the management server 200 (step S107; NO), it remains in standby mode.

[0075] For example, the reception unit 102 receives from the management server 200 whether or not seller V1, identified by seller identification information "V1", is able to sell therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx".

[0076] In step S108, if the reception unit 102 determines that the received result indicates that the item is available for sale (step S108; YES), the payment processing unit 103 executes the payment processing for the purchase of the item placed in the electronic cart (step S109). Then, once the payment processing is complete, the second registration unit 104 registers the purchase history of the specific item for which the payment processing has been completed, along with the information on the item's availability included in the received result (step S110). On the other hand, if the reception unit 102 determines that the received result indicates that the item is not available for sale (step S108; NO), the presentation unit 105 prompts the shopper terminal 300 to remove the specific item placed in the electronic cart (step S111).

[0077] For example, when the reception unit 102 determines that it has received information from the management server 200 indicating that seller V1, identified by seller identification information "V1", is able to sell therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx", and also receives the availability information "December 12, 2024, 10:00:00 AM", the payment processing unit 103 provides the electronic cart page shown in Figure 8, which displays the details of the products placed in the electronic cart. The payment processing unit 103 proceeds with the payment processing according to the instructions from shopper S1. Then, when the payment processing for therapeutic food P1 for shopper S1 is completed, the second registration unit 104 associates the purchase history information indicating that shopper S1 purchased therapeutic food P1 from seller V1 with the availability information "December 12, 2024, 10:00:00 AM" and registers it as sales information. On the other hand, if the reception unit 102 receives information from the management server 200 that seller V1, identified by seller identification information "V1", is unable to sell therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx", the presentation unit 105 provides the shopper terminal 300 of shopper S1 with the removal notification page 500-4 shown in Figure 9.

[0078] (5. Management processing by the management server of the embodiment) The management process performed by the management server 200 in this embodiment will be explained with reference to Figure 12. For example, when the management server 200 receives a report from the sales server 100, it starts the management process shown in Figure 12.

[0079] The determination unit 201 determines whether or not sales availability information has been reported from the sales server 100 (step S201). If the determination unit 201 determines that sales availability information has been reported (step S201; YES), it determines whether or not the period from the date and time indicated by the date and time information included in the reported sales availability information to the present is within a predetermined period (step S202). On the other hand, if the determination unit 201 determines that sales availability information has not been reported (step S201; NO), it proceeds to step S204.

[0080] For example, if the determination unit 201 determines that sales availability information has been reported from the sales server 100, it determines whether the period from the date and time information "December 12, 2024, 10:00:00" to the present is within a predetermined period of "6 months". On the other hand, if the determination unit 201 determines that sales availability information has not been reported from the sales server 100, it proceeds to step S204.

[0081] In step S202, if the determination unit 201 determines that the period from the date and time indicated by the date and time information included in the reported availability information to the present is within a predetermined period (step S202; YES), it determines that the seller identified by the seller identification information reported together with the availability information is available to sell the specific product identified by the product identification information reported together with the availability information (step S203). Then, the process proceeds to step S207. On the other hand, if the determination unit 201 determines that the period from the date and time indicated by the date and time information included in the reported availability information to the present exceeds a predetermined period (step S202; NO), the process proceeds to step S204.

[0082] For example, if the period from the date and time information "December 12, 2024, 10:00:00" included in the availability information to the present is within the predetermined period of "6 months", the determination unit 201 determines that seller V1, identified by seller identification information "V1" reported together with the availability information, is available to sell the therapeutic food P1, identified by product identification information "xxxxxxxxxxxxx" reported together with the availability information. Then, the process proceeds to step S207. On the other hand, if the determination unit 201 determines that the period from the date and time information "December 12, 2024, 10:00:00" included in the availability information to the present exceeds the predetermined period of "6 months", the process proceeds to step S204.

[0083] The determination unit 201 determines whether the seller identified by the reported seller identification information is able to sell the specific product identified by the reported product identification information (step S204). If the determination unit 201 determines that the seller identified by the reported seller identification information is able to sell the specific product identified by the reported product identification information (step S204; YES), the acquisition unit 202 acquires purchase information, including buyer identification information for identifying the shopper, by having the shopper terminal 300 identified by the reported terminal identification information input it (step S205). Next, when the purchase information is acquired, the first registration unit 203 registers the reported seller identification information, the reported product identification information, and the acquired purchase information in association (step S206). Then, the notification unit 204 notifies the sales server 100 of the result that the seller identified by the reported seller identification information is able to sell the specific product identified by the reported product identification information (step S207).

[0084] For example, if the determination unit 201 refers to the seller list and determines that seller V1, identified by the reported seller identification information "V1", is able to sell therapeutic food P1, identified by the reported product identification information "xxxxxxxxxxxxx", the acquisition unit 202 provides the shopper terminal 300 with terminal identification information "yyyyy" with the purchase information input page 600 shown in Figure 6 for inputting purchase information, and acquires the name "aaa aaa", email address "bbb@bbb.com", and telephone number "ccc-ccc-ccc" as purchaser identification information, "eee Hospital" as prescriber identification information, and the pet name "dd" as other purchase information. The first registration unit 203 associates the seller identification information "V1" of seller V1, the product identification information "xxxxxxxxxxxxx" of therapeutic food P1, the purchase information name "aaa aaa", email address "bbb@bbb.com", telephone number "ccc-ccc-ccc", pet name "dd" and "eee Hospital", and the sales permission information "December 12, 2024, 10:00:00" with each other and registers them as management information. The notification unit 204 then notifies the sales server 100 that seller V1, identified by the seller identification information "V1", is authorized to sell therapeutic food P1, identified by the product identification information "xxxxxxxxxxxxx", and also notifies the sales authorization information "December 12, 2024, 10:00:00".

[0085] On the other hand, if the determination unit 201 determines that the seller identified by the reported seller identification information is unable to sell the specific product identified by the reported product identification information (step S204; NO), the notification unit 204 notifies the sales server 100 that the seller identified by the reported seller identification information is unable to sell the specific product identified by the reported product identification information (step S208).

[0086] For example, if the determination unit 201 refers to the seller list and determines that seller V1, identified by the reported seller identification information "V1", is unable to sell the therapeutic food P1, identified by the reported product identification information "xxxxxxxxxxxxx", the notification unit 204 notifies the sales server 100 that seller V1, identified by the seller identification information "V1", is unable to sell the therapeutic food P1, identified by the product identification information "xxxxxxxxxxxxx".

[0087] According to this embodiment, when a shopper places an item in their electronic cart on an electronic marketplace, they can purchase it if the management server, which manages the item's information, determines that the seller is able to sell the item. If the seller determines that the item is not available for sale, the shopper is prompted to remove the item from their electronic cart. This appropriately informs the shopper that the seller's sale of the item is authorized by the manufacturer or other entity that manages the item's information. Furthermore, it is possible to limit the items purchased on the electronic marketplace to those sold by sellers authorized by the manufacturer or other entity, thereby eliminating counterfeit and expired items. In addition, the management server registers the shopper's purchase information in association with seller identification information and item identification information, so that the manufacturer or other entity that manages the item's information can manage the information of both the buyer and the seller. Moreover, instead of the shopper's information being automatically transmitted from the sales server to the management server, the management server requests the shopper to input their purchase information, thus ensuring the protection of the shopper's personal information.

[0088] Furthermore, according to this embodiment, shoppers are required to input prescribing information to identify the veterinarian or hospital that prescribed the pet's therapeutic diet. This allows manufacturers and other entities that manage product information to manage prescribing information in addition to purchaser and seller information.

[0089] Furthermore, according to this embodiment, the sales server registers availability information, including the date and time information of the date and time when it was determined to be available for sale and purchase information was acquired, as notified by the management server. This allows the sales server to identify the time when it was determined to be available for sale.

[0090] Furthermore, according to this embodiment, the management server determines that an item is available for sale if the period from the date and time information included in the availability information reported by the sales server to the present falls within a predetermined period. This allows the management server to eliminate the need to acquire purchase information, thereby improving processing efficiency. Additionally, it eliminates the need for shoppers to enter purchase information each time they make a purchase.

[0091] (6. Variant) Although embodiments of the present invention have been described above, various modifications and applications are possible when implementing the present invention.

[0092] In the above embodiment, the information included in the available-for-sale information was described as date and time information indicating the date and time when the purchase information was acquired, but the information included in the available-for-sale information is not limited to this. For example, the available-for-sale information may include license information granted by the manufacturer of a specific product to the seller, and the determination unit 201 of the management server 200 may determine whether or not the product is available for sale based on the expiration date of the license information.

[0093] Furthermore, although Figure 11 shows the specific product sales process executed by the sales server 100 in the above embodiment, the order of the steps is not limited to this. For example, the order of the process in step S103 and the process in step S104 may be swapped. Also, the order of the process in step S105 and the process in step S106 may be swapped.

[0094] Furthermore, by applying an operating program that defines the operation of the sales server 100 or management server 200 according to the above embodiment to an existing personal computer or information terminal device, it is also possible to make the personal computer or information terminal device function as the sales server 100 or management server 200 according to the embodiment.
