[0037] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0038] The word “exemplary” is used hereinafter to mean “serving as an example, example, or illustration.” Any embodiment described as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0039] The terms "first" and "second" in this document are used for descriptive purposes only and should not be understood as explicitly or implicitly indicating relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of this application, unless otherwise specified, "plurality" means two or more.

[0040] The design concept of the embodiments of the present application is introduced below.

[0041] At present, in the electronic invoice service platform for enterprises, the services of invoice issuance and the generation and delivery of electronic invoice format files are implemented by different systems. The invoice issuance process needs to be implemented through traditional tax control equipment. If enterprises want to use traditional tax control equipment, they need to apply for and use it at the tax bureau, which is inconvenient to expand the equipment. In addition, traditional tax control equipment usually needs to be managed uniformly by setting up golden tax disks, tax control disk groups, etc., which takes up a lot of space.

[0042] In view of this, the embodiments of the present application provide an invoice service platform, an invoice business processing method, an electronic device and a storage medium, which can use virtual tax control equipment to implement invoicing business. Compared with traditional physical tax control equipment, virtual tax control equipment saves space, and the online application of virtual tax control equipment can be realized through the tax control invoicing system, which is flexible to expand.

[0043] The following is an introduction to the invoice service platform of the embodiment of the present application with reference to the accompanying drawings.

[0044] Figure 1 An invoice service platform of an embodiment of the present application is shown, referring to Figure 1 As shown, the invoice service platform includes a front-end system 10, a tax control invoicing system 20, an electronic invoice service system 30, a big data analysis system 40 and an operation and maintenance monitoring system 50.

[0045] Specifically, each system of the invoice service platform can be one or more servers, among which the tax control invoicing system can be based on the national secret tax control server of the new tax bureau standard, which can support virtual tax control equipment.

[0046] The front-end system is used to receive invoicing business requests sent by the enterprise side and send the invoicing business requests to the tax control invoicing system.

[0047] Specifically, the front-end system can be connected with the business system of the enterprise, such as the Enterprise Resource Planning (ERP) system, etc., to receive user invoicing, query, electronic invoice delivery and other requests sent by the enterprise's ERP and other business systems, realize the scheduling, distribution and feedback of business requests, and provide users with convenient, fast, integrated and unified external services. It realizes functions such as request data verification, unified interface service, unified job scheduling, and unified information push.

[0048] The above invoicing service request may include the invoice information of the enterprise side, the tax control device corresponding to the enterprise side, etc., wherein the invoice information may include enterprise information, invoice amount, commodity information, etc. The tax control device may be the virtual tax control device described below, or a traditional tax control device.

[0049] The tax control invoicing system is used to receive tax control equipment applications sent by the enterprise side, and send an audit request to the tax bureau side based on the tax control equipment application. If the audit approval information is received from the tax bureau side, a virtual tax control device will be allocated to the enterprise side; if an invoicing business request is received from the front-end system, and the enterprise side that sends the invoicing business request corresponds to the virtual tax control device, the invoicing business corresponding to the invoicing business request will be executed through the virtual tax control device corresponding to the enterprise side.

[0050] In specific implementation, the tax control invoicing system can be based on the above-mentioned national secret tax control server. The enterprise can initiate an application for the use of virtual tax control equipment to the national secret tax control server, and upload it to the tax bureau through the national secret tax control server. After the tax bureau approves it, the enterprise can use the virtual tax control equipment to conduct business. It should be noted that an enterprise can apply for multiple virtual tax control equipment, which facilitates the flexible expansion of virtual tax control equipment managed by the invoice service platform. Since virtual tax control equipment does not take up space, it greatly saves space compared to traditional tax control equipment.

[0051] In addition, traditional tax control equipment cannot be applied for and issued online. It is necessary to apply for and issue it at the tax bureau, and the equipment needs to be shut down to add new equipment. It is impossible to achieve flexible online expansion of the equipment. However, the embodiments of the present application can achieve flexible online expansion of the equipment without shutting down.

[0052] In an optional embodiment, in order to facilitate the access of traditional tax control devices to the invoice service platform, a software and hardware adaptation layer can be added to the tax control invoicing system, that is, the invoicing business requests received by the front-end system can be routed through the software and hardware adaptation layer. The invoicing business requests of the virtual tax control device call the virtual tax control device, and the invoicing business requests of the traditional tax control device call the physical tax control device. There is no need to make any changes to the software and hardware of the traditional physical tax control device, and it can be connected to the invoice service platform for use.

[0053] Furthermore, the tax control invoicing system is also used for: if an invoicing business request is received from the front-end system, and the enterprise side that sends the invoicing business request corresponds to a physical tax control device (i.e., the above-mentioned traditional tax control device), then the invoicing business request will be sent to the physical tax control device corresponding to the enterprise side, so that the physical tax control device corresponding to the enterprise side will execute the invoicing business corresponding to the invoicing business request.

[0054] In an optional embodiment, the front-end system is also used to: receive an invoice delivery request sent by the enterprise side, and send the invoice delivery request to the electronic invoice service system.

[0055] The electronic invoice service system is used to obtain the corresponding invoice information from the tax control invoicing system according to the invoice delivery request, and select the invoice layout corresponding to the invoice delivery request from a variety of preset invoice layouts, generate an electronic invoice layout file according to the selected invoice layout based on the obtained invoice information, and send the electronic invoice layout file to the enterprise end through the front-end system.

[0056] In a specific implementation, the invoice delivery request may include invoice information, invoice layout, etc. The electronic invoice service system may encapsulate multiple service functions such as the generation, query, inspection, printing, downloading, and delivery of electronic invoice layout files, and provide a unified service interface for the front-end system to call. The above-mentioned multiple preset invoice layouts may include, for example, traditional PDF (Portable Document Format) format layout files and OFD (Open Fixed-layout Document) format layout files that support the tax bureau's electronic invoice specifications. In addition, it can also support the delivery of electronic invoice layout files in multiple ways such as the Web, WeChat, and SMS.

[0057] Furthermore, the big data analysis system is used to obtain the invoice business data generated by the tax control invoicing system during the execution of the invoicing business, and perform big data analysis on the invoice business data.

[0058] Specifically, invoice business data may include user data, business operation data, etc. The big data analysis system may specifically perform the following analyses on user data and business operation data:

[0059] Create user portraits based on user data to identify the target users of the enterprise;

[0060] Analyze the business conditions of the enterprise based on its operating data to determine target operating products and predict business trends.

[0061] Specifically, the big data analysis system can extract user data from invoice business data, wherein the user data may include user attributes and user behavior data such as user industry, capital situation, transaction scale, transaction commodity, risk situation, preference information, etc.

[0062] The following is an example of the process of the big data analysis system performing big data analysis on user data.

[0063] The big data analysis system can use a clustering algorithm to cluster multiple reference attribute information such as user industry, capital situation, transaction scale, transaction items, risk situation, preference information, etc., for example, using a k-means clustering algorithm, which can specifically include the following steps:

[0064] 1) Divide the reference attribute information (attribute objects) corresponding to multiple users into K groups, and randomly select K attribute information as the initial clustering centers.

[0065] 2) Calculate the distance (i.e., similarity) between each attribute object and each cluster center (K ​​objects), and assign each attribute object to the cluster center closest to it to form a cluster (each cluster center and the attribute objects assigned to them represent a cluster).

[0066] 3) Continue to iterate the above 1) and 2) processes until the cluster center no longer changes, and the clustering is complete. Through the K-Means algorithm, users can be clustered and evaluated from multiple indicator dimensions such as user industry, capital situation, transaction scale, transaction items, risk, preference, etc., to complete user portraits and help companies better locate high-quality customers.

[0067] Furthermore, the big data analysis system can also extract business data from invoice business data. Among them, business data can include purchase and sales invoice data, order data, etc., and these data are analyzed using regression algorithms to predict future product sales trends (sales volume, sales price, etc.), determine advantageous products such as cash cows, predict future sales trends, and provide a basis for the company's strategic decision-making.

[0068] The following is an example of how a big data analysis system analyzes enterprise business data. The specific steps include:

[0069] 1) Determine the independent variable and dependent variable based on the forecast target: sales volume is the dependent variable. Through market research and business transaction data (invoices, orders, etc.), find the relevant influencing factors (i.e. independent variables) related to sales volume and select the main influencing factors.

[0070] 2) Establish a regression prediction model: Conduct statistical analysis based on past data of independent variables and dependent variables (purchase and sales invoice data, order data, etc.), and on this basis establish a regression analysis equation, namely a regression analysis prediction model.

[0071] 3) Correlation analysis: Perform mathematical and statistical analysis on the influencing factors (independent variables) and the predicted objects (dependent variables) to find out the correlation.

[0072] 4) Test the regression prediction model and calculate the prediction error: test the correlation regression equation and evaluate the prediction error.

[0073] 5) Calculate and determine the predicted value: Use the regression prediction model to calculate the predicted value, and conduct a comprehensive analysis of the predicted value to determine the final predicted value. Through the continuous iteration of intelligent algorithms and machine learning, the automation and intelligence of the system will be gradually realized, and based on the results of big data analysis, it will help avoid tax-related risks and improve the business level of enterprises.

[0074] Furthermore, the operation and maintenance monitoring system is used to obtain the operating status of the front-end system, tax control invoicing system, electronic invoice service system and big data analysis system respectively, and monitor the operating status of each system.

[0075] The tax control invoicing system of the embodiment of the present application is based on a national secret tax control server, which realizes the integrated management and service of invoice issuance and electronic invoice format files. In the invoice issuance link, there is no need to set up a golden tax disk or a tax control disk group, which saves computer room space. One server can realize the flexible expansion of corporate tax numbers, supporting up to 5,000 tax numbers, and the business and management efficiency is doubled, reducing the system maintenance cost of the enterprise. In addition, the system is compatible with traditional physical tax control equipment, which can realize the reuse of equipment.

[0076] Below Figure 2 The architecture diagram of the invoice service platform shown introduces the invoice service platform of the embodiment of the present application.

[0077] like Figure 2 As shown, the invoice service platform of the embodiment of the present application includes a front-end system, a tax control invoicing system, an electronic invoice service system, a big data analysis system and an operation and maintenance monitoring system, wherein the tax control invoicing system is based on the national secret tax control server of the new standard of the tax bureau, and is compatible with the traditional tax control equipment currently used by enterprises. The back end of the platform is connected to the tax bureau to realize tax management functions such as application, issuance, uploading, and tax copying of value-added tax invoices. The front end of the platform is connected to the enterprise business ERP system to realize the issuance of value-added tax invoices (all types of invoices) and the generation, printing, query, delivery and other services of electronic invoices, meeting the enterprise's demand for unified management of value-added tax invoices. The system also provides functions such as automated operation and maintenance monitoring and big data statistical analysis to help enterprises achieve digital transformation of their businesses.

[0078] The following is an introduction to each system of the invoice service platform.

[0079] Front-end system: connects to enterprise ERP and other business systems, receives invoicing, query, electronic invoice delivery and other requests from enterprise ERP and other business system users, realizes the scheduling, distribution and feedback of business requests, and provides users with convenient, fast, integrated and unified external services. It realizes functions such as request data verification, unified interface service, unified job scheduling, and unified information push.

[0080] Tax control invoicing system: Provides unified invoice management interface service, connects to the front-end system, encapsulates the VAT invoice application, issuance, query, cancellation, tax reporting and other businesses, and provides unified interface services for front-end system calls; provides unified system management functions, realizes user authority management, parameter setting, equipment management, ticket source management, tax reporting management, query statistics and other system management functions, and facilitates users to maintain the system. Through the national secret tax control server, the user's tax control equipment can be flexibly expanded. Through the national secret tax control server, the user's virtual tax control equipment can be applied for and issued. One enterprise can apply for multiple virtual tax control equipment, which is convenient for the flexible expansion of user equipment managed by the invoice service platform. Compatible with traditional tax control equipment, the system is based on the national secret tax control server to achieve hardware equipment adaptation, compatible with traditional tax control equipment, and convenient for enterprises to reuse old equipment. Realize the tax management function of the tax bureau, connect to the tax bureau end, realize online changes, invoice upload, tax reporting, monitoring feedback and other tax management functions, and realize tax closed-loop management.

[0081] Electronic invoice server system: It connects to the front-end system, encapsulates multiple service functions such as electronic invoice format file generation, query, inspection, printing, downloading, and delivery, and provides a unified service interface for the front-end system to call. The system supports traditional PDF format format files, and supports OFD format format files specified by the tax bureau's electronic invoice, and can achieve a smooth transition from PDF format files to OFD format files. The system supports the delivery of electronic invoice format files through multiple methods such as Web, WeChat, and SMS.

[0082] Operation and maintenance monitoring system: collects the operating status of servers, operating systems, databases, middleware, and front-end systems involved in the electronic invoice platform, electronic invoice service systems, tax control invoicing systems, national secret tax control servers and other tax control equipment, big data analysis systems, etc., analyzes the collected monitoring information, and triggers early warning notifications when the set monitoring threshold is exceeded, thereby realizing the system monitoring, business monitoring, and monitoring early warning functions of the electronic invoice platform, and generating monitoring reports.

[0083] Big data analysis system: Based on the company's invoice data, business data, system operation and maintenance data, etc., a big data analysis platform is established, and artificial intelligence algorithms are introduced to conduct statistical analysis and data mining on the company's tax-related, invoice-related, business, operation and maintenance monitoring data. Through the continuous iteration of intelligent algorithms and machine learning, the intelligent operation and maintenance of the system is gradually realized, and based on the results of big data analysis, it helps to avoid tax-related risks and improve the company's operating level.

[0084] Next, Figure 3 Taking the invoice issuance flow chart shown as an example, the invoice issuance process of the invoice service platform is introduced.

[0085] like Figure 3As shown, the enterprise business system sends an invoice issuance request to the electronic invoice service platform (i.e., the invoice service platform of the embodiment of the present application). The electronic invoice service platform can receive the invoice issuance request through the front-end system, and then verify the invoice issuance data in the invoice issuance request; if the verification is passed, the dispatch is requested, that is, the tax control device corresponding to the enterprise business system that sends the invoice issuance request is determined, for example, the corresponding virtual tax control device, and the corresponding virtual tax control device is called by the tax control invoicing system to issue the invoice; if the invoice issuance data verification fails, an error message is sent to the enterprise business system. When issuing an invoice, the tax control invoicing system can also determine whether the issuance is successful. If the issuance is successful, the invoice can be uploaded to the tax bureau end. After receiving the invoice, the tax bureau end sends a receiving information feedback to the tax control invoicing system, and then the tax control invoicing system can determine whether the invoice is uploaded successfully based on the receiving information feedback; if the issuance is unsuccessful, an error message can be sent to the enterprise business system.

[0086] Further, Figure 4 Taking the electronic invoice delivery flow chart shown in the figure as an example, the electronic invoice delivery process of the invoice service platform is introduced.

[0087] like Figure 4 As shown, the enterprise business system sends an electronic invoice delivery request to the electronic invoice service platform. The electronic invoice service platform can receive the electronic invoice delivery request through the front-end system, and then request scheduling to query the invoice information corresponding to the electronic invoice delivery request. Specifically, requesting scheduling means determining the tax control device corresponding to the enterprise business system that sends the invoice issuance request, for example, the corresponding virtual tax control device, and then calling the corresponding virtual tax control device through the tax control invoicing system to obtain the invoice information corresponding to the electronic invoice delivery request, and then obtaining the invoice information through the electronic invoice service system, generating an electronic invoice format file based on the invoice information and signing and stamping it, and judging whether the electronic invoice format file is generated successfully. If successful, the generated electronic invoice format file is sent to the enterprise business system; if unsuccessful, an error message can be sent to the enterprise business system.

[0088] Based on the same inventive concept, the present application embodiment provides an invoice business processing method, which can be applied to the tax control invoicing system of the above embodiment. Figure 5 As shown, the invoice business processing method includes the following steps:

[0089] Step S501, receiving a tax control equipment application sent by an enterprise, and sending a review request to the tax bureau according to the tax control equipment application;

[0090] Step S502: if the tax bureau receives approval information, a virtual tax control device is allocated to the enterprise;

[0091] Step S503: If an invoicing service request sent by the front-end system is received, and the enterprise end of the invoicing service request corresponds to a virtual tax control device, the invoicing service corresponding to the invoicing service request is executed through the virtual tax control device corresponding to the enterprise end.

[0092] In specific implementation, the tax control invoicing system can be based on the national secret tax control server in the above embodiment. The enterprise can initiate an application for the use of virtual tax control equipment to the national secret tax control server, and upload it to the tax bureau through the national secret tax control server. After the tax bureau approves it, the enterprise can use the virtual tax control equipment to conduct business. It should be noted that an enterprise can apply for multiple virtual tax control devices, which facilitates the flexible expansion of virtual tax control devices managed by the invoice service platform. Since virtual tax control devices do not take up space, they greatly save space compared to traditional tax control devices.

[0093] In an optional embodiment, in order to facilitate the access of traditional tax control devices to the invoice service platform, a software and hardware adaptation layer can be added to the tax control invoicing system, that is, the invoicing business requests received by the front-end system can be routed through the software and hardware adaptation layer. The invoicing business requests of the virtual tax control device call the virtual tax control device, and the invoicing business requests of the traditional tax control device call the physical tax control device. There is no need to make any changes to the software and hardware of the traditional physical tax control device, and it can be connected to the invoice service platform for use.

[0094] Furthermore, the tax control invoicing system can also perform the following steps:

[0095] If an invoicing business request is received from the front-end system, and the enterprise side sending the invoicing business request corresponds to a physical tax control device, the invoicing business request will be sent to the physical tax control device corresponding to the enterprise side, so that the physical tax control device corresponding to the enterprise side will execute the invoicing business corresponding to the invoicing business request.
