Description

Technical Field

[0001] The present disclosure relates to the field of invoicing, and in particular, to an invoicing method, device, storage medium and electronic device. Background Art

[0002] In actual invoicing scenarios, the company name, bank account number, taxpayer identification number, address, telephone number and other information involved in the invoice is easy to change, and the information is too long to be remembered or easy to remember incorrectly, resulting in incorrect invoicing information or slow invoicing, which affects the user experience.

[0040] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0041] First, the application scenario of the present invention is introduced. The present invention is mainly used in the scenario of issuing invoices. Usually, when consumers apply for invoices, the information involved in the invoices, such as the company name, bank account number, taxpayer identification number, address, telephone number, etc., is easy to change, and the information is too long to be remembered, or it is easy to remember incorrectly, resulting in incorrect invoicing information or slow invoicing speed, thus affecting the user experience.

[0042] In order to improve the efficiency of invoicing, the relevant technology changes the original process of the seller filling in the header information to the buyer filling in the header information after scanning the same QR code, and then the seller continues to complete the subsequent invoicing operations through the invoicing software. However, when most invoicing software is used for invoicing, the amount of enterprise data that can be recommended is limited, the data is outdated, the header information is incomplete or inaccurate, and the data cannot be updated in time, which affects the efficiency of invoicing. Therefore, a universal, accurate and comprehensive enterprise business card information database is needed to provide data support for various invoicing software.

[0043] In order to solve the above-mentioned problems, the present disclosure provides an invoicing method, device, storage medium and electronic device, which can pre-generate a corporate business card database by sorting out the invoice information issued by the enterprise and the invoice information received by the enterprise, and the corporate business card database includes corporate business card information of multiple enterprises (such as enterprise name, enterprise unified social credit code, taxpayer identification number, address, telephone number, bank and account number, region and other information). In this way, the server can receive an invoicing request message sent by the terminal, and the invoicing request message includes a preset purchaser identifier with a preset number of characters, and the preset number of characters is less than the total number of characters corresponding to the preset purchaser identifier; according to the preset purchaser identifier with the preset number of characters, the server can generate an invoicing request message from the preset purchaser identifier. A preset number of candidate business card information is obtained from the generated business card database, and the preset number of candidate business card information is sent to the terminal, so that the terminal determines the target business card information from the preset number of candidate business card information, and issues an invoice based on the target business card information. In this way, the user only needs to enter part of the header information (that is, the preset purchaser identification with a preset number of characters) to obtain all the business card information corresponding to the purchaser message to be filled in the invoice to be issued from the pre-generated business card database, thereby solving the problem of incomplete business data when querying the purchaser's business data during business invoicing, and at the same time improving the invoicing efficiency, solving the problem of invoicing queuing, and improving user experience.

[0044] In addition, the corporate business card database can be used as a public service to provide an external interface for the invoicing software, and the plug-in design makes it easier to deploy new extended functions.

[0045] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0046] Figure 1 is a flowchart of a method for issuing invoices according to an exemplary embodiment, which can be applied to a server, such as Figure 1 As shown, the method comprises the following steps:

[0047] In step S101, an invoicing request message sent by a receiving terminal includes a preset purchaser identifier with a preset number of characters, and the preset number of characters is less than the total number of characters corresponding to the preset purchaser identifier.

[0048] Among them, the preset purchaser identification may include identification information such as the purchaser's name, the purchaser's taxpayer identification number, or the purchaser's enterprise's unified social credit code.

[0049] Taking into account that some corporate business card information is too long and difficult to remember, users who apply for invoices (generally purchasing users) can usually only provide partial information about the purchasing company. Therefore, the preset purchaser identifier with a preset number of characters is the partial information of the purchasing company entered by the user. For example, the preset purchaser identifier with a preset number of characters can be the last four digits of the purchaser's taxpayer identification number, or any three characters in the purchaser's name. This is only an example and the present disclosure does not limit this.

[0050] In step S102, a preset number of candidate business card information is obtained from a pre-generated business card database according to the preset buyer identifier having the preset number of characters.

[0051] Among them, the corporate business card database includes corporate business card information of multiple companies, which may include company name (or "taxpayer name"), taxpayer identification number, company address, telephone number, bank and account number, region and other information. The region is usually the prefecture-level city where the company is located.

[0052] Normally, the preset purchaser identifier entered by the user when issuing an invoice is different, and the corresponding strategy for obtaining the candidate company business card information is also different. In this step, if the preset purchaser identifier is the purchaser's taxpayer identification number, a preset number of the candidate company business card information is determined according to a preset right-matching fuzzy matching algorithm; if the preset purchaser identifier is the purchaser's name, a preset number of the candidate company business card information is determined according to a preset left-right matching fuzzy matching algorithm.

[0053] In step S103, a preset number of candidate enterprise business card information is sent to the terminal, so that the terminal determines target enterprise business card information from the preset number of candidate enterprise business card information and issues an invoice according to the target enterprise business card information.

[0054] By adopting the above method, the user only needs to enter part of the header information (i.e. the preset purchaser identifier with a preset number of characters) to obtain all the information of the business card corresponding to the purchaser message to be filled in the invoice to be issued from the pre-generated business card database, thereby solving the problem of incomplete business data when querying the purchaser's business data when the company issues the invoice. At the same time, it improves the invoicing efficiency, solves the problem of invoicing queuing, and improves the user experience.

[0055] Figure 2 is a flow chart of a method for issuing invoices according to an exemplary embodiment, which is applied to a terminal provided with invoicing software, such as Figure 2 As shown, the method comprises the following steps:

[0056] In step S201, an invoicing request message input by a user is obtained, the invoicing request message including a preset purchaser identifier with a preset number of characters, the preset number of characters being less than the total number of characters corresponding to the preset purchaser identifier.

[0057] Among them, the preset purchaser identification may include identification information such as the purchaser's name, the purchaser's taxpayer identification number, or the purchaser's enterprise's unified social credit code.

[0058] In an actual invoicing scenario, the selling user can issue an invoice for the purchasing user through the invoicing software set on the terminal. Specifically, the invoice header information and other relevant information can be filled in the purchasing information on the interface of the invoicing software. In this case, the terminal can obtain the invoicing request message.

[0059] In step S202, the invoicing request message is sent to the server.

[0060] In step S203, a preset number of candidate enterprise business card information sent by the server is received.

[0061] Among them, the candidate corporate business card information is the information retrieved by the server from a pre-generated corporate business card database based on part of the information of the preset purchaser identifier. The corporate business card database includes corporate business card information of multiple companies. The corporate business card information may include company name (or "taxpayer name"), taxpayer identification number, company address, telephone number, bank and account number, region and other information. The region is usually the prefecture-level city where the company is located.

[0062] In step S204, target enterprise business card information is determined from a preset number of candidate enterprise business card information according to a triggering operation of the user, and invoices are issued according to the target enterprise business card information.

[0063] By adopting the above method, the user only needs to enter part of the header information (i.e., a preset purchaser identifier with a preset number of characters) to obtain all the information of the business card corresponding to the purchaser message to be filled in the invoice to be issued from the pre-generated business card database, thereby solving the problem of incomplete business data when querying the purchaser's business data when the company issues the invoice. At the same time, it improves the invoicing efficiency, solves the problem of invoicing queuing, and improves the user experience.

[0064] Figure 3 is a flow chart of a method for issuing invoices according to an exemplary embodiment. Figure 3 As shown, the method comprises the following steps:

[0065] In step S301, the terminal obtains an invoicing request message input by a user, and sends the invoicing request message to a server, where the invoicing request message includes a preset purchaser identifier with a preset number of characters.

[0066] Among them, the preset number of characters is less than the total number of characters corresponding to the preset buyer identification, and the preset buyer identification may include identification information such as the buyer's name, the buyer's taxpayer identification number or the unified social credit code of the buyer's enterprise.

[0067] In an actual invoicing scenario, the selling user can issue an invoice for the purchasing user through the invoicing software set on the terminal. Specifically, the invoice header information and other relevant information can be filled in the purchasing information on the interface of the invoicing software. In this case, the terminal can obtain the invoicing request message.

[0068] Taking into account that some corporate business card information is too long and difficult to remember, users who apply for invoices (generally purchasing users) can usually only provide partial information about the purchasing company. Therefore, the preset purchaser identifier with a preset number of characters is the partial information of the purchasing company entered by the user. For example, the preset purchaser identifier with a preset number of characters can be the last four digits of the purchaser's taxpayer identification number, or any three characters in the purchaser's name. This is only an example and the present disclosure does not limit this.

[0069] In step S302, the server obtains a preset number of candidate business card information from a pre-generated business card database according to a preset buyer identifier with a preset number of characters.

[0070] Among them, the corporate business card database includes corporate business card information of multiple companies. Among them, corporate business card generation refers to the process of sorting out the invoice information issued by the company and the invoice information received by the company, classifying them according to the invoicing region, and forming a corporate business card information data set. After that, data integration and analysis can be carried out according to the region, and the company's invoicing frequency can be calculated to generate or update the corporate business card. The corporate business card information may include the company name (or "taxpayer name"), taxpayer identification number, company address, telephone number, bank and account number, region and other information. The region is usually the prefecture-level city where the company is located.

[0071] Normally, the preset purchaser identifier entered by the user when issuing an invoice is different, and the corresponding strategy for obtaining the candidate company business card information is also different. In this step, if the preset purchaser identifier is the purchaser's taxpayer identification number, the server can determine a preset number of the candidate company business card information according to the preset right-matching fuzzy matching algorithm; if the preset purchaser identifier is the purchaser's name, the server can determine a preset number of the candidate company business card information according to the preset left-right matching fuzzy matching algorithm.

[0072] For example, if the query is based on the purchaser's taxpayer identification number, the query begins after it is determined that the user has entered the last 4 digits (i.e., the preset number of characters) of the taxpayer identification number, and fuzzy matching can be performed in the business card database in a right-matching manner to obtain a preset number (for example, 15) of the candidate business card information. In addition, if the query is based on the purchaser's name, the query begins after it is determined that the user has entered 3 (i.e., the preset number of characters) of the purchaser's name, and fuzzy matching can be performed in a left-right matching manner to obtain a preset number of the candidate business card information. The above examples are for illustrative purposes only and the present disclosure is not limited to this.

[0073] It should be noted that the specific implementation method of determining the candidate enterprise business card information according to the fuzzy matching algorithm can refer to the relevant description in the prior art, and the present disclosure does not limit this.

[0074] In step S303, the server sends the preset number of candidate business card information to the terminal.

[0075] After obtaining the preset number of candidate business card information, the terminal can display the candidate business card information to the user in the form of a recommended result list. In order to facilitate the user to find the target business card information they actually need more quickly, the list can display each candidate business card information from top to bottom according to the frequency of use, so as to improve the user experience.

[0076] In addition, to save display space, the purchaser name and / or taxpayer identification number corresponding to each candidate enterprise business card information may be displayed in the recommendation result list, so that users can quickly find the target enterprise business card information.

[0077] In step S304, the terminal determines target enterprise business card information from a preset number of candidate enterprise business card information according to the user's triggering operation, and issues an invoice according to the target enterprise business card information.

[0078] After the terminal displays a preset number of candidate corporate business card information to the user in the form of a recommended result list, the user can select the target corporate business card information in the recommended result list through a trigger operation. In this way, after determining the target corporate business card information, the terminal can automatically fill in all the corporate business card information required for invoicing of the target company in the corporate business card database into the purchaser information of the invoice, thereby realizing automatic invoicing based on the target corporate business card information, avoiding the complicated operation of users filling in each purchaser information one by one, and improving the accuracy and efficiency of invoicing.

[0079] In step S305, the terminal sends the latest issued invoice to the server.

[0080] The latest invoice issued may be the latest invoice issued by the invoice software on the terminal at the current moment.

[0081] In order to ensure the accuracy of the corporate business card information stored in the corporate business card database, it is necessary to timely update the corporate business card information of each company stored in the corporate business card database. Therefore, in this step, the terminal can send the latest invoice to the server so that the server can update the corporate business card information of the corresponding company according to the seller information in the latest invoice.

[0082] In step S306, when the server determines that the seller's enterprise information in the latest invoice is inconsistent with the corresponding enterprise business card information in the enterprise business card database, it updates the enterprise business card database according to the seller's enterprise information in the latest invoice.

[0083] For example, assuming that the seller information in the latest invoice is: the seller's name is A, the taxpayer identification number is 123456, the address is B, and the bank account is Industrial and Commercial Bank of China, the corporate business card information of Company A stored in the corporate business card database is: name is A, taxpayer identification number is 123456, address is A, and the bank account is China Construction Bank. After the server obtains the latest invoice, it can identify that the seller information in the latest invoice is inconsistent with the corporate business card information of Company A stored in the corporate business card database. In this case, the server can update the corporate business card information of Company A in the corporate business card database according to the seller information in the latest invoice. Specifically, the address of Company A is updated from A to B, and the bank account of Company A is updated from China Construction Bank to Industrial and Commercial Bank of China, so as to ensure the accuracy of the corporate business card information of Company A stored in the corporate business card database and improve the accuracy of subsequent invoicing. The above examples are only illustrative examples and the present disclosure is not limited to this.

[0084] By adopting the above method, the user only needs to enter part of the header information (i.e., a preset purchaser identifier with a preset number of characters) to obtain all the information of the business card corresponding to the purchaser message to be filled in the invoice to be issued from the pre-generated business card database, thereby solving the problem of incomplete business data when querying the purchaser's business data when the company issues the invoice. At the same time, it improves the invoicing efficiency, solves the problem of invoicing queuing, and improves the user experience.

[0085] Figure 4 is a flowchart of a method for pre-generating a corporate business card database according to an exemplary embodiment. The method can be applied to a server. Figure 4 The pre-generation process of the enterprise business card database is described as follows: Figure 4 As shown, the method comprises the following steps:

[0086] In step S401, for each of the multiple information collection invoices, the seller's company information and the buyer's company information are collected from the information collection invoice.

[0087] Normally, the server can form a corporate information data set by organizing the invoice information issued by the company and the invoice information received by the company, and dynamically generate the latest corporate business card after data integration and comparative analysis.

[0088] In a possible application scenario, the server can obtain invoices issued by the invoicing software on each terminal, and the information collection invoice is the invoice obtained by the server from the invoicing software on each terminal.

[0089] In addition, invoice information generally includes two parts: buyer information and seller information. It can be understood that the seller information in the invoice is closer to the actual latest corporate business card information than the buyer information. Therefore, in the present disclosure, corporate business card information is collected from the seller information in the invoice first. In the case that the company does not issue an invoice as the seller, the corporate business card information can be collected from the buyer information in the invoice.

[0090] In step S402, multiple first invoice sets are determined based on the seller enterprise information corresponding to each information collection invoice, and different seller enterprises correspond to different first invoice sets.

[0091] For example, assume that there are currently six information collection invoices, 1, 2, 3, 4, 5, and 6, among which the seller on invoice 1 is A and the buyer is C, the seller on invoice 2 is B and the buyer is E, the seller on invoice 3 is C and the buyer is E, the seller on invoice 4 is A and the buyer is F, the seller on invoice 5 is D and the buyer is F, and the seller on invoice 6 is B and the buyer is E. After determining multiple first invoice sets according to the seller enterprise information corresponding to each information collection invoice, the following first invoice sets can be determined: the set corresponding to seller A {invoice 1, invoice 4}, the set corresponding to seller B {invoice 2, invoice 6}, the set corresponding to seller C {invoice 3}, and the set corresponding to seller D {invoice 5}. The above examples are only illustrative and the present disclosure is not limited to this.

[0092] In step S403, the target purchasing enterprise is determined according to the purchasing enterprise information corresponding to each information collection invoice, and the target purchasing enterprise includes other enterprises in the purchasing enterprise except the selling enterprise.

[0093] In the case where the company does not issue an invoice as the seller, the company's business card information can be collected from the buyer's information in the invoice. Therefore, in this step, the target buyer company can be determined based on the buyer company information corresponding to each information collection invoice.

[0094] Continuing with the above example, the purchasing company in invoice 1 is C, the purchasing company in invoice 2 is E, the purchasing company in invoice 3 is E, the purchasing company in invoice 4 is F, the purchasing company in invoice 5 is F, and the purchasing company in invoice 6 is E. Based on the sales companies obtained in step S402, the four companies A, B, C, and D, then the target purchasing companies are companies E and F. This is just an example, and the present disclosure does not limit this.

[0095] In step S404, the enterprise business card database is generated according to the plurality of first invoice sets and the second invoice sets corresponding to the target purchasing enterprise, and different target purchasing enterprises correspond to different second invoice sets.

[0096] For example, based on the above example, the second invoice sets corresponding to the two target purchasing companies E and F are: the set corresponding to buyer E is {invoice 2, invoice 3, invoice 6}, and the set corresponding to buyer F is {invoice 4, invoice 5}.

[0097] In this step, for each first invoice set in the multiple first invoice sets, it is determined whether the seller company information on each invoice in the first invoice set is consistent. When it is determined that the seller company information on each invoice in the first invoice set is consistent, the seller company information corresponding to the first invoice set can be used as the corporate business card information of the seller company corresponding to the first invoice set; when it is determined that there is inconsistency in the seller company information on the invoices in the first invoice set, the seller company information on the first target invoice in the first invoice set can be used as the corporate business card information of the seller company corresponding to the first invoice set, wherein the first target invoice is the most frequently used invoice in the first invoice set.

[0098] In addition, if the invoices in the first invoice set have the same usage frequency, the seller's company information on the invoice corresponding to the latest invoice issuance date in the first invoice set can be used as the business card information of the seller's company corresponding to the first invoice set.

[0099] In this step, for each second invoice set in the multiple second invoice sets, it can be determined whether the purchasing company information on each invoice in the second invoice set is consistent. When it is determined that the purchasing company information on each invoice in the second invoice set is consistent, the purchasing company information corresponding to the second invoice set can be used as the corporate business card information of the purchasing company corresponding to the second invoice set; when it is determined that there is inconsistency in the purchasing company information on the invoices in the second invoice set, the purchasing company information on the second target invoice in the second invoice set can be used as the corporate business card information of the purchasing company corresponding to the second invoice set, wherein the second target invoice is the most frequently used invoice in the second invoice set.

[0100] In addition, when the invoices in the second invoice set have the same usage frequency, the purchaser company information on the invoice corresponding to the latest invoice issuance date in the second invoice set is used as the business card information of the purchaser company corresponding to the second invoice set.

[0101] It should also be noted that, in order to improve the accuracy of recommending invoicing information based on the corporate business card information stored in the corporate business card database, in another possible implementation method of the present disclosure, the corporate business card information of enterprises located in different invoicing areas can be further classified and stored in combination with the invoicing region. Therefore, in the present disclosure, before generating the corporate business card database based on the multiple first invoice sets and the second invoice sets corresponding to the target purchasing enterprise, the invoicing region corresponding to each invoice collected by the information can be obtained. In this way, the corporate business card database can be generated based on the invoicing region, the multiple first invoice sets and the second invoice sets corresponding to the target purchasing enterprise.

[0102] Among them, in the process of obtaining the invoicing region corresponding to each invoice of the information collection, the invoicing region can be intercepted according to the unified social credit code or taxpayer identification number of the sales enterprise, and priority is given to intercepting from the unified social credit code. Under normal circumstances, the region represented by the 3-8 digit administrative division code in the unified social credit code of the sales enterprise is the invoicing region; the region represented by the 3-6 digit regional code in the taxpayer identification number of the sales enterprise is the invoicing region.

[0103] By adopting the above method, the latest business card information of each enterprise can be recorded through a pre-generated business card database, so as to provide comprehensive and accurate enterprise information for invoicing and improve invoicing efficiency. In addition, the business card database can be used as a public service to provide an external interface for invoicing software, and the plug-in design makes it easier to deploy new extended functions.
