Description

Technical Field

[0001] This invention relates to the field of e-commerce transaction digitization and financial and tax compliance technology, specifically to an e-commerce front-end order real-time synchronization back-end financial and tax compliance processing system. Background Technology

[0002] Against the backdrop of rapid digital development in the e-commerce industry, online order transactions are characterized by high frequency, multiple states, and fast turnover. Events such as order creation, payment, and refunds occur in real time, placing stringent demands on the synchronization and compliance of front-end order data with back-end financial accounting and tax processing. Simultaneously, the tax regulatory system is constantly improving, with increasingly stringent requirements for the standardization of invoice issuance, tax calculation, and data retention in e-commerce transactions. Enterprises need to achieve accurate correlation between order data and financial and tax data to avoid tax compliance risks and ensure the accuracy of financial accounting.

[0003] Existing solutions for integrating e-commerce orders with financial and tax processing are mostly semi-automated, exhibiting significant technical shortcomings: order data collection lacks real-time performance, relying primarily on batch synchronization, and lacks independent processing channels for different order events, leading to data duplication and temporal discrepancies; the matching degree between generated financial vouchers and order event types is low, with no standardized algorithm matching logic, and lax debit / credit balance verification, easily resulting in accounting deviations; tax invoicing is disconnected from financial vouchers, creating compliance loopholes for issuing invoices without vouchers, and insufficient element verification dimensions before invoicing, easily leading to errors in tax rate and coding matching; there is a lack of a closed-loop order status write-back mechanism, preventing real-time synchronization of financial and tax processing results to front-end orders, and the absence of a unified data consistency verification system across the entire chain, with isolated data in each module, making it difficult to promptly block abnormal data and easily causing inconsistencies in financial and tax data.

[0004] The limitations of existing technologies result in low efficiency in the collaboration between front-end order processing and back-end financial and tax processing for e-commerce companies. This not only increases the manual verification costs for finance personnel but also easily leads to problems such as non-compliant tax invoicing, accounting errors, and difficulties in data traceability, significantly increasing the financial and tax supervision risks and operational management costs of enterprises. Currently, there is no real-time processing system in the industry that can integrate order collection, voucher generation, tax invoicing, status write-back, and end-to-end verification. Therefore, developing a real-time synchronized processing system for front-end order processing and back-end financial and tax compliance that is adapted to the characteristics of e-commerce transactions has become an urgent need for e-commerce companies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an e-commerce front-end order real-time synchronization system for back-end financial and tax compliance processing. Through an event-driven architecture, it enables real-time linkage between order events and financial and tax processing, automatically generates vouchers and strongly binds them to tax invoicing, thus avoiding compliance loopholes. It constructs a full-link data verification system to verify data consistency from multiple dimensions, instantly blocking anomalies and issuing warnings to ensure data accuracy. It supports closed-loop order status write-back and full data archiving, improving financial and tax processing efficiency and supporting enterprise digital management.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a real-time e-commerce front-end order synchronization back-end financial and tax compliance processing system, the system comprising: an order collection module, a financial voucher engine generation module, a tax invoicing interface processing module, an order status closed-loop write-back module, and a full-link data verification module;

[0007] The order acquisition module: monitors in real time the three types of order events generated by the e-commerce front end: order creation, order payment, and order refund. It simultaneously captures all order elements of the corresponding order, encapsulates them into a standardized real-time data stream, and pushes them to the financial voucher engine generation module according to the order of the events.

[0008] The financial voucher engine generation module receives standardized real-time data streams, uses the order number as the unique association dimension, matches preset accounting rules according to the order event type, generates corresponding voucher entries, and integrates them to form a compliant voucher data package.

[0009] The tax invoicing interface processing module receives compliant voucher data packets, extracts the corresponding elements associated with invoicing, connects to the tax invoicing system interface to complete compliant invoice processing operations, and generates full-element invoice result data.

[0010] The order status closed-loop write-back module receives the full-element result data of the invoice, uses the order number as the associated primary key, writes the invoice information back to the corresponding e-commerce order and updates the order status, synchronously writes the full-link data into the order ledger, and pushes it to the full-link data verification module.

[0011] The end-to-end data verification module receives all data pushed by each node in the end-to-end, corresponding to the same order number. Using the order number as a unified index, it performs consistency verification on the order event, voucher entries, invoice elements, and order ledger. It also executes process blocking and abnormal warning for abnormal data that fails the verification.

[0012] Furthermore, the order acquisition module adopts an event-driven distributed message listening architecture, configuring independent listening ports and message queue channels for three types of order events: order creation, order payment, and order refund. Each channel is bound to an event identifier and data verification logic that uniquely corresponds to the order event type. After listening to an order event, the module first verifies the order event triggering sequence and data integrity, filters out invalid events that are triggered repeatedly, and then captures all order elements with the order number as the unique primary key. These all order elements include the order event type identifier, the total transaction amount including tax, the actual payment amount, the refund amount, the product details, the applicable VAT rate for the product, the product tax classification code, the buyer's invoicing information, and the order transaction status. Finally, all elements are encapsulated into a standardized real-time data stream that conforms to a common data exchange format.

[0013] Furthermore, after receiving the standardized real-time data stream, the financial voucher engine generation module decapsulates and verifies the data using the order number as the unique dimension, extracting the order event type identifier, amount element, tax rate element, and transaction entity information from the data stream; then, it matches the accounting voucher template uniquely corresponding to the order event type using preset accounting rules; finally, it completes the amount calculation and entry generation of voucher entries based on the order data, with each order corresponding to a unique set of voucher entries, generating a voucher data package containing the voucher number, voucher entry details, associated order number, accounting date, and debit / credit balance verification result.

[0014] Furthermore, the financial voucher engine generation module determines the accounting voucher template type through an order event matching coefficient algorithm, and then completes the accurate calculation of the entry amount through a voucher debit / credit balancing accounting algorithm. The specific workflow is as follows:

[0015] The first step is to calculate the matching result using the order event matching coefficient algorithm. The formula is as follows:

[0016]

[0017] in, This is the order event matching coefficient, used to determine the accounting voucher template type; The weighting factor for the order creation event is fixed at 1. Create an event flag for the order; the value is 1 when the order event is created, and 0 when it is not a creation event. This is the weighting coefficient for the order payment event, with a fixed value of 1. This is the order payment event flag; it takes a value of 1 when the order event is payment and a value of 0 when it is a non-payment event. The weighting coefficient for order refund events is fixed at -1; This is a flag for order refund events. The value is 1 when the order event is a refund and 0 when it is a non-refund event.

[0018] The second step, according to The calculation result matches the corresponding accounting voucher template: when =1 and When =1, match the accounts receivable accounting voucher template; when =1 and When =1, match the accounting voucher template for main business revenue and output tax; when When =−1, match the red-ink accounts receivable and red-ink revenue accounting voucher templates;

[0019] The third step is to calculate the journal entry amount using the voucher debit / credit balancing algorithm, and then calculate the total transaction amount including tax. The formula is:

[0020]

[0021] in, This refers to the total transaction amount, including tax, for the corresponding order. This refers to the revenue from goods excluding tax. The applicable VAT rate applies to the goods;

[0022] The formula for the debit-credit balancing accounting algorithm is as follows:

[0023]

[0024] in, The total debit amount for all entries in this voucher; The total credit amount for all entries in this voucher;

[0025] The fourth step is to generate the voucher entry when the total transaction amount A (including tax) matches the actual order amount, and the total debit amount D equals the total credit amount C (i.e., D−C=0). If any check fails, a data anomaly warning is triggered, and the voucher generation process for this order is terminated.

[0026] Furthermore, the tax invoicing interface processing module uses compliant voucher data packages as the sole legal basis for invoicing, prohibiting invoicing operations triggered without voucher data. The specific workflow is as follows: receiving voucher data packages and completing data decapsulation; extracting elements associated with invoicing, including the total invoice amount including tax, applicable VAT rate, commodity tax classification code, buyer's invoicing information, associated order number, and associated voucher number; matching the field formats of the extracted elements to complete the format standardization processing of the invoicing data; connecting to the tax invoicing system interface through an encrypted communication channel, and completing the corresponding invoice processing operation according to the order event type corresponding to the voucher, where order payment events correspond to the issuance of blue-letter VAT invoices, order refund events correspond to the issuance of red-letter VAT invoices, and erroneous invoicing corresponds to invoice voiding; extracting the full-element result data of the completed invoice and pushing it to the order status closed-loop write-back module.

[0027] Furthermore, the tax invoicing interface processing module has a built-in invoicing compliance pre-verification unit: before sending an invoicing request to the tax invoicing system interface, it performs multi-dimensional compliance verification on the invoicing elements. The verification dimensions include the validity verification of the buyer's invoicing information, the matching verification of the commodity tax classification code and commodity category, the consistency verification of the applicable tax rate with the tax rate corresponding to the upstream order and voucher, and the equivalence verification of the invoicing amount and the voucher amount. Only when all verification items pass, the invoicing request is allowed to be sent. If any verification item fails, the invoicing request is immediately blocked, and the corresponding compliance risk warning information is output.

[0028] Furthermore, the workflow of the order status closed-loop write-back module is as follows: receiving the full-element result data of the invoice, and matching the extracted associated order number with the corresponding original order in the e-commerce front-end order system; writing the invoice code, invoice number, total invoice amount including tax, amount excluding tax, VAT amount, invoice date, and invoice status information into the financial and tax information fields of the corresponding order, one by one; simultaneously updating the financial accounting status and tax invoicing status of the order according to the invoice type and status, where a normal blue-ink invoice corresponds to updating the order's financial accounting status to "accounted" and tax invoicing status to "invoiced", and a red-ink invoice corresponds to updating the order's financial accounting status to "reversed" and tax invoicing status to "reversed"; writing the original order event information, full-element information of the voucher entries, full-element information of the invoice, and order status change information corresponding to the order into the order ledger, and pushing the full-archived data in the order ledger to the end-to-end data verification module.

[0029] Furthermore, the end-to-end data verification module completes the quantitative verification of end-to-end data through a consistency matching algorithm, the calculation formula of which is:

[0030]

[0031] in, This represents the total data matching degree across the entire link, with a value ranging from 0 to 1. The verification was successful. The verification failed. , , , The preset weighting coefficients are set to 0.4, 0.3, 0.2, and 0.1 respectively. For the matching degree of the amount dimension, the value is 1 when the total amount of the order event including tax = the total amount of the voucher entry = the total amount of the invoice = the amount of the order ledger record, otherwise the value is 0; The value is set to 1 when the applicable VAT rate of the order = the tax rate on the voucher = the applicable tax rate on the invoice, and the tax classification code of the goods on the order = the tax code on the voucher = the tax classification code on the invoice; otherwise, it is set to 0. The degree of association matching is set to 1 when the order number is uniquely associated with the voucher number, invoice number, and order ledger record, and 0 otherwise. The matching degree for the status dimension is 1 when the order transaction status = voucher accounting status = invoice issuance status = order ledger archiving status, and 0 otherwise.

[0032] The corresponding operation is executed based on the calculation result of the total matching degree M of the whole link data. When M=1, the final archiving of the order is completed. When M<1, the process blockade and abnormal warning are triggered.

[0033] Furthermore, the end-to-end data verification module uses the order number as a unified index to establish a unique binding mapping relationship between order events, voucher entries, invoice elements, and order ledgers; it performs consistency comparisons from four dimensions: amount, tax rate and tax code, association relationship, and status; based on the comparison results, it outputs a verification conclusion. When all dimensions are completely consistent, the verification is deemed successful, and the final archiving of the order's end-to-end process is completed; when any dimension is inconsistent, the verification is deemed unsuccessful, the order archiving process is immediately blocked, the field containing the abnormal data is located, and detailed abnormal warning information is output.

[0034] Compared with existing technologies, this e-commerce front-end order real-time synchronization back-end financial and tax compliance processing system has the following advantages:

[0035] I. This invention establishes an event-driven order collection and full-link automated processing architecture to achieve real-time synchronous linkage between e-commerce front-end order events and back-end financial and tax processing. This breaks the traditional segmented and manual financial and tax processing model, allowing financial and tax processing for various events such as order creation, payment, and refund to be triggered instantly with transaction behavior. Simultaneously, it automatically generates voucher entries based on preset rules, achieving strong binding between tax invoicing and compliant voucher data packages. Combined with multi-dimensional compliance pre-verification before invoicing, it avoids tax compliance loopholes such as invoicing without vouchers and data mismatch from the process design perspective. This ensures that every link in financial accounting and tax processing accurately corresponds to order transaction data, comprehensively improving the timeliness and compliance of e-commerce enterprises' financial and tax processing, and adapting to the full-process requirements of digital tax supervision.

[0036] Second, this invention constructs a full-link data verification system with order numbers as a unified index, enabling multi-dimensional data consistency verification of order events, voucher entries, invoice elements, and order ledgers. It establishes a unique binding mapping relationship for data at each stage, solving the problems of fragmented modules and data disconnect in traditional financial and tax processing. For abnormal data that fails verification, it executes immediate process blocking and precise early warnings, quickly locating abnormal data fields and ensuring the accuracy and consistency of data throughout the entire process. Simultaneously, through closed-loop write-back of order status and ledger archiving of all data, it achieves traceability and controllability throughout the entire lifecycle of order financial and tax processing, significantly reducing the cost of manual verification and anomaly correction, improving the efficiency of financial and tax processing for massive, fragmented e-commerce orders, and providing complete technical support for enterprise digital financial and tax management.

[0042] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0043] Example 1

[0044] The order acquisition module employs an event-driven distributed message listening architecture. It configures a dedicated listening port and message queue channel for order refund events. Each channel is bound to a unique event identifier and data validation logic corresponding to the order refund event. This independent channel configuration ensures the accuracy and specificity of order refund event listening, preventing confusion with other order events. Upon real-time monitoring of an order refund event triggered by the e-commerce frontend, it first rigorously verifies the triggering sequence and data integrity of that event, focusing on confirming that the refund event is triggered based on a valid, already paid order. This ensures the authenticity and validity of the refund event from the source. Simultaneously, it filters out duplicate invalid refund events and eliminates fraudulent refund data. Then, all order elements are precisely captured, with the order number as the unique primary key. These elements include the order event type identifier, total transaction amount including tax, actual payment amount, refund amount, product details, applicable VAT rate, product tax classification code, buyer's invoicing information, and order transaction status. Finally, all elements are encapsulated into a standardized real-time data stream that conforms to a common data exchange format. This standardized encapsulation format ensures the consistency of refund data processing in the subsequent financial module, avoiding accounting errors caused by inconsistent data formats. The standardized real-time data stream is then pushed to the financial voucher engine generation module according to the chronological order of events, ensuring that the financial red-ink reversal accounting and the actual refund process remain synchronized.

[0045] The financial voucher engine generation module receives standardized real-time data streams from the order collection module. It decapsulates and verifies the data using the order number as the unique dimension. A dedicated verification process ensures the accuracy and integrity of refund data during the transfer process, preventing data deviations from affecting subsequent red-ink reversal accounting. It then extracts the order event type identifier, amount element, tax rate element, and transaction entity information from the data stream. Finally, it determines the accounting voucher template type using an order event matching coefficient algorithm. The formula is: ,in, For order event matching coefficients; Weighting factor for the order creation event; Create an event flag for the order; The weighting coefficient for order payment events; This is the order payment event flag; The weighting coefficient for order refund events; This is the identifier for the order refund event. The algorithm can accurately match the corresponding red-ink reversal accounting template based on the actual order event of the refund, ensuring the standardization and accuracy of financial red-ink reversal accounting. After matching the red-ink accounts receivable and red-ink revenue accounting voucher templates, the algorithm uses the voucher debit / credit balancing to accurately calculate the entry amount and the total transaction amount including tax. The formula is: The execution of the debit-credit balancing accounting algorithm is as follows: ,in, This refers to the total transaction amount, including tax, for the corresponding order. This refers to the revenue from goods excluding tax. The applicable VAT rate applies to the goods; The total debit amount for all entries in this voucher; This is the total credit amount of all entries for this voucher. The voucher entry is generated when the total transaction amount (including tax, A) matches the actual order amount, and the total debit amount (D) equals the total credit amount (C), i.e., D − C = 0. This algorithm strictly adheres to the accounting red-ink entry accounting principles, controlling the accuracy and balance of red-ink entry amounts. During the accounting process, it simultaneously confirms that the total transaction amount (including tax) matches the actual order refund amount, and that the total debit and credit amounts of the voucher are balanced. This ensures the financial compliance of red-ink voucher entries from a monetary perspective. After generating a unique set of red-ink voucher entries for each refund order, these entries are integrated to form a compliant voucher data package containing the voucher number, voucher entry details, associated order number, accounting date, and debit / credit balance verification results. This compliant voucher data package becomes the sole legal basis for subsequent red-ink tax invoicing, providing solid financial support for tax red-ink operations. This data package is then pushed to the tax invoicing interface processing module.

[0046] The tax invoicing interface processing module uses the compliant voucher data package pushed by the financial voucher engine generation module as the sole legal basis for invoicing. It strictly prevents tax violations such as triggering red-ink invoicing without voucher data, ensuring the compliance of tax red-ink invoicing operations. After receiving the voucher data package, it decapsulates the data and accurately extracts the elements associated with the red-ink invoicing, including the total invoice amount including tax, applicable VAT rate, commodity tax classification code, buyer's invoicing information, associated order number, and associated voucher number. Then, it performs field format matching on the extracted elements to standardize the invoicing data format. This standardized format ensures the compatibility of the red-ink invoicing data with the tax invoicing system interface, smoothly completing the red-ink invoicing operation. During processing, the built-in invoicing compliance pre-verification unit performs multi-dimensional compliance verification on the red-ink invoicing elements, including buyer's invoicing information. The system performs multiple pre-verification checks, including verifying the validity of information, the matching of commodity tax classification codes with commodity categories, the consistency of applicable tax rates with upstream order and voucher tax rates, and the equivalence of invoice amounts with voucher amounts. These multi-dimensional pre-verification checks can proactively identify tax compliance risks in red-letter invoice data and prevent errors in red-letter invoicing. After all verification items pass, the system connects to the tax invoicing system interface through an encrypted communication channel. This encrypted communication channel ensures the security of red-letter invoice data during transmission and prevents leakage of refund red-letter invoice data. Then, based on the order refund event corresponding to the voucher, the red-letter VAT invoice is issued, completing the tax-compliant red-letter invoicing process. After issuance, all invoice elements are fully extracted. The complete red-letter invoice data provides accurate basis for subsequent order status write-back and is then pushed to the order status closed-loop write-back module.

[0047] The order status closed-loop write-back module receives the full-element result data of red-letter invoices pushed by the tax invoicing interface processing module. Using the extracted associated order number as the core, it accurately matches the corresponding original order in the e-commerce front-end order system. This unique number matching ensures the accurate association between red-letter invoice information and refund orders, guaranteeing a one-to-one correspondence between the red-letter invoice information and the original transaction order. Then, it accurately writes all information of the red-letter invoice—code, invoice number, total invoice amount including tax, amount excluding tax, VAT amount, invoice date, and invoice status—into the corresponding order's financial and tax information fields. This achieves real-time updates of the e-commerce front-end order's financial and tax red-letter invoice information, allowing the e-commerce client to intuitively view detailed red-letter invoice information. Simultaneously, it updates the order information synchronously based on the type and status of the red-letter invoice. The financial accounting status and tax invoicing status of orders are updated to "reversed in red ink" and "reversed in red ink" respectively. This clear status update allows e-commerce operations to keep track of the progress of financial and tax reversal processing after order refunds in real time, facilitating subsequent management of refunded orders. Then, the original order event information, full information of red ink voucher entries, full information of red ink invoices, and order status change information corresponding to the order are all written into the order ledger. This achieves centralized archiving and retention of financial and tax data for the entire refund reversal process, providing complete data support for subsequent financial reversal reconciliation and tax reversal verification. Finally, the full archived data in the order ledger is pushed to the full-link data verification module, providing a comprehensive and complete data source for the verification of refund reversal data throughout the entire process.

[0048] The end-to-end data verification module receives all refund and reversal data for the same order number pushed by each node in the end-to-end process. Using the order number as a unified index, it establishes a unique binding mapping relationship between the order refund event, the reversal voucher entry, the reversal invoice element, and the order ledger. This unique binding mapping ensures the relevance and uniqueness of the end-to-end refund and reversal data, ensuring that the reversal data is closely linked to the original transaction data and remains consistent. Finally, a consistency matching algorithm is used to quantitatively verify the end-to-end refund and reversal data. The formula is as follows: ,in, The total matching degree of the entire data link; , , , These are preset weighting coefficients; Matching degree for monetary amount; The degree of matching between tax rates and tax code dimensions; The degree of matching in relation to the relationship; For the state dimension matching degree, this algorithm can scientifically and accurately quantify the consistency of the entire refund red-ink invoice data chain. It also performs a comprehensive consistency comparison from four dimensions: amount, tax rate and tax code, correlation, and state. This multi-dimensional comparison can comprehensively investigate inconsistencies in the entire refund red-ink invoice data chain. Verification confirms that the refund amount of the order refund event is completely consistent with the red-ink invoice amount in the voucher entry, the invoice amount on the red-ink invoice, and the refund amount recorded in the order ledger. Furthermore, the applicable VAT rate for the order matches the tax rate on the voucher and the applicable tax rate on the red-ink invoice. The order's commodity tax classification code is completely consistent with the voucher tax calculation code and the red-ink invoice tax classification code. The order number is uniquely bound to the voucher number, red-ink invoice number, and order ledger record. The order refund transaction status is completely consistent with the voucher red-ink reversal accounting status, red-ink invoice issuance status, and order ledger archiving status. The overall data matching degree across the entire chain is determined to be 1. After verification, the final archiving of the entire refund order process is completed, realizing a closed loop of red-ink reversal financial and tax processing for e-commerce orders from refund application to red-ink financial accounting and red-ink tax invoicing. Figure 1 As shown, this ensures both financial and tax compliance throughout the entire order refund process.

[0049] This embodiment addresses the scenario of a full refund and issuance of a red-letter VAT invoice for a paid e-commerce order. It fully verifies the adaptability, rigor, and compliance of the e-commerce front-end order real-time synchronization back-end financial and tax compliance processing system in reverse transaction scenarios. The system's five modules, combined with the business characteristics of refund red-letter invoices, carry out targeted financial and tax processing work, realizing a full-chain financial and tax closed loop in reverse transaction scenarios. The order acquisition module accurately monitors single refund events, ensuring the authenticity and validity of refund events and data through rigorous verification, providing accurate raw data for red-ink invoice processing. The financial voucher engine generation module uses a dedicated algorithm to match red-ink voucher templates, completing accurate accounting for red-ink entries. The generated compliant red-ink voucher data package becomes the sole legal basis for red-ink invoicing, ensuring the standardization of financial red-ink invoicing accounting. The tax invoicing interface processing module conducts multi-dimensional pre-verification around red-ink invoicing, completing the issuance of red-ink invoices through an encrypted channel, achieving compliant red-ink invoicing at the tax level. The order status closed-loop write-back module accurately writes red-ink invoice information back to the original order, updates the financial and tax status, and completes the ledger archiving of all red-ink invoicing data, achieving real-time synchronization between front-end orders and back-end red-ink invoicing data. The full-link data verification module conducts multi-dimensional consistency comparisons and algorithmic quantitative verification of red-ink invoicing data, ensuring the consistency of data throughout the entire refund red-ink invoicing process.

[0050] Example 2

[0051] The order acquisition module employs an event-driven distributed message listening architecture. Separate listening ports and message queue channels are configured for order creation and order payment events. Each channel is bound to a unique event identifier and data validation logic corresponding to the order event type. This architecture ensures the real-time and independent listening of different order events, avoiding mutual interference in event processing. After real-time listening to the order creation and order payment events triggered sequentially by the e-commerce frontend, the module first rigorously validates the triggering sequence and data integrity of both types of order events, filtering out duplicate and invalid events and eliminating erroneous data to ensure the basic validity of the data. The system accurately captures all order elements, with the order number as the unique primary key. These elements include the order event type identifier, total transaction amount including tax, actual payment amount, product details, applicable VAT rate, product tax classification code, buyer's invoicing information, and order transaction status. All these elements are then encapsulated into a standardized real-time data stream conforming to a common data exchange format. This standardized encapsulation ensures the uniformity and adaptability of subsequent modules in receiving and processing order data. The standardized real-time data stream is then pushed to the financial voucher engine generation module according to the chronological order of events. This chronological push allows subsequent financial accounting to proceed in an orderly manner according to the actual transaction process.

[0052] The financial voucher generation module receives standardized real-time data streams from the order acquisition module. It then performs data decapsulation and secondary verification using the order number as the unique dimension. This dual verification further ensures the accuracy of basic order data, preventing data loss or tampering during the transfer process. Subsequently, it accurately extracts order event type identifiers, amount elements, tax rate elements, and transaction entity information from the data stream. Finally, it determines the accounting voucher template type using an order event matching coefficient algorithm. This algorithm accurately matches the corresponding accounting template based on the actual order event, ensuring the relevance and standardization of accounting calculations, and matching the main business... After generating the revenue and output tax accounting voucher templates, the accurate calculation of journal entry amounts is further completed using the voucher debit-credit balancing algorithm. This algorithm strictly adheres to accounting standards to control the accuracy of journal entry amounts. During the calculation process, it simultaneously confirms that the total transaction amount including tax is consistent with the actual order amount, and that the total debit amount and total credit amount of the voucher are balanced. This ensures the compliance of the voucher entries from a monetary perspective. After generating a unique set of voucher entries for each order, these are integrated to form a compliant voucher data package containing the voucher number, voucher entry details, associated order number, accounting date, and debit-credit balancing verification results. Figure 2 As shown, a compliant data package of vouchers can serve as the sole legal basis for subsequent tax invoicing processes, thus solidifying the compliance foundation for tax processing from a financial perspective. The data package is then pushed to the tax invoicing interface processing module.

[0053] The tax invoicing interface processing module uses the compliant voucher data package pushed by the financial voucher engine generation module as the sole legal basis for invoicing. This prevents tax violations caused by invoicing operations triggered without voucher data from the source. After receiving the voucher data package, the module first decapsulates the data and accurately extracts the elements associated with invoicing, including the total invoice amount including tax, the applicable VAT rate, the commodity tax classification code, the buyer's invoicing information, the associated order number, and the associated voucher number. Then, it performs field format matching on the extracted elements to complete the format standardization of the invoicing data. Format standardization ensures perfect compatibility between the invoicing data and the tax invoicing system interface, avoiding invoicing failures due to format issues. During the processing, the built-in invoicing compliance pre-verification unit performs multi-dimensional compliance verification on the invoicing elements, including verification dimensions such as the buyer's invoicing. The system performs multi-dimensional pre-verification checks, including information validity verification, matching of commodity tax classification codes with commodity categories, consistency of applicable tax rates with upstream order and voucher tax rates, and equivalence of invoice amounts with voucher amounts. These checks proactively identify compliance risks in invoice data, resolving tax issues before the invoicing process. After all verification items pass, the system connects to the tax invoicing system interface via an encrypted communication channel. This encrypted communication channel ensures the security of invoice data during transmission, preventing data leakage or tampering. Then, based on the order payment event corresponding to the voucher, the blue-letter VAT invoice is issued. After issuance, all invoice elements are extracted, providing comprehensive and accurate data for subsequent order status write-back. This data is then pushed to the order status closed-loop write-back module.

[0054] The order status closed-loop write-back module receives the full-element invoice results data pushed by the tax invoicing interface processing module. Using the extracted associated order number as the core, it accurately matches the corresponding original order in the e-commerce front-end order system. This unique number matching ensures accurate association between invoice information and order, preventing misattribution. Then, it accurately writes all information—invoice code, invoice number, total invoice amount including tax, amount excluding tax, VAT amount, invoice date, and invoice status—into the corresponding order's financial and tax information fields. This achieves real-time and complete updates of the e-commerce front-end order's financial and tax information, allowing the e-commerce client to intuitively view detailed invoice information. Simultaneously, it updates the information based on the type and status of normal blue-ink invoices. The financial accounting status and tax invoicing status of new orders are updated to "accounted for" and "invoiced" respectively. This clear status update allows e-commerce operations to keep track of the order's financial and tax processing progress in real time, facilitating subsequent order management and follow-up. Then, the original order event information, full information of voucher entries, full information of invoice elements, and order status change information corresponding to the order are uniformly written into the order ledger, realizing centralized archiving and retention of financial and tax data across the entire order chain. This provides complete data support for subsequent financial reconciliation and tax audits. Finally, the full archived data in the order ledger is pushed to the full-chain data verification module, providing a complete and comprehensive data source for full-chain data verification.

[0055] The end-to-end data verification module receives all data pushed by each node in the end-to-end chain corresponding to the same order number. Using the order number as a unified index, it establishes a unique binding mapping relationship between order events, voucher entries, invoice elements, and order ledgers. This unique binding mapping ensures the relevance and uniqueness of the end-to-end data, preventing data disconnection. Then, a consistency matching algorithm is used to perform quantitative verification of the end-to-end data. This algorithm can scientifically and accurately determine the consistency of the end-to-end data. Simultaneously, it performs a comprehensive consistency comparison from four dimensions: amount, tax rate and tax code, relationship, and status. This multi-dimensional comparison allows for a comprehensive investigation of the entire end-to-end data. Inconsistencies in the data were verified and confirmed to be completely consistent with the total amount of the order event (including tax), the total amount of the voucher entries, the total amount of the invoice, and the amount recorded in the order ledger. The applicable VAT rate for the order was completely consistent with the tax rate calculated on the voucher and the applicable tax rate on the invoice. Furthermore, the tax classification code for the goods in the order was completely consistent with the tax calculation code on the voucher and the tax classification code on the invoice. The order number was uniquely bound to the voucher number, invoice number, and order ledger record. The order transaction status was completely consistent with the voucher accounting status, invoice issuance status, and order ledger archiving status. The overall data matching degree across the entire chain was determined to be 1. After successful verification, the final archiving of the entire order process was completed. Figure 3 As shown, this achieves a closed-loop financial and tax processing system for e-commerce orders, from order creation and payment to financial accounting and tax invoicing, ensuring the financial and tax compliance of the entire commodity transaction process.

[0056] This embodiment focuses on the scenario of creating payment and issuing blue-letter VAT invoices for normal e-commerce transactions. It fully implements the entire process of real-time synchronization between the e-commerce front-end order and the back-end financial and tax compliance processing system. The system's five core modules each perform their respective functions, linking and coordinating efficiently to achieve seamless integration and real-time synchronization between front-end order transactions and back-end financial and tax processing. From the order acquisition module, which uses an event-driven architecture to accurately listen to order events, verify data, and standardize encapsulation, laying a precise data foundation for subsequent financial and tax processing; to the financial voucher engine generation module, which uses a dedicated algorithm to match voucher templates and calculate journal entries, generating compliant voucher data packages to solidify the compliance foundation of financial accounting; to the tax invoicing interface processing module, which uses vouchers as the sole basis and performs multi-dimensional pre-verification to securely issue blue-letter invoices, avoiding tax invoicing violations from the source; to the subsequent order status closed-loop write-back module, which realizes real-time updates of invoice information and order status and completes the ledger archiving of all data; and finally, to the full-link data verification module, which uses algorithmic quantitative verification and multi-dimensional consistency comparison to complete the full-link compliant archiving of orders.
