Official website entry of the national unified invoice inquiry platform for invoice verification, a must-read for finance

How to find the official website entry of the national unified invoice inquiry platform for invoice verification? A compliance guide for efficient verification by finance staff

Every month during tax filing season, finance staff Xiao Wang logs into the tax bureau website one by one to verify the authenticity of dozens of invoices, eyes sore and efficiency low, and still worries that missing one will cause tax risks. Although the National VAT Invoice Verification Platform is the only official entrance, manual verification is time-consuming and labor-intensive, and verification demand has surged in the era of fully digitalized e-invoices. The solution is to embed verification into the process and achieve integrated automatic verification, duplicate checking, and booking. Kailing Technology's input VAT invoice management directly connects to the tax bureau to automatically obtain all invoice sources, verifying and checking duplicates to prevent duplicate or missed reporting, upgrading finance from "manual verification" to "intelligent risk control."

▍1. Where exactly is the official website entry for the national unified invoice query platform?

According to an announcement of the State Taxation Administration, the National VAT Invoice Verification Platform (https://inv-veri.chinatax.gov.cn) is the only official verification entry point, supporting verification of all invoice types including special VAT invoices, ordinary invoices, and fully digitalized e-invoices. Enterprise finance staff need to verify invoices promptly after obtaining them to guard against fake and out-of-control invoices. However, manual verification requires entering the code, number, invoicing date, etc. one by one, which is inefficient and error-prone. According to the Measures of the People's Republic of China for the Administration of Invoices, invoices that do not meet regulations may not be used as financial reimbursement vouchers, so verification is a baseline compliance action.

▍II. Why does manual verification become the invisible killer of finance efficiency?

Manual verification is not only time-consuming but also has three major pain points: first, logging in and entering information one by one, with overtime becoming the norm during peak periods; second, verification results require manual recording, prone to missed or duplicate checks; third, it cannot be integrated with posting and filing processes, causing delayed risk detection. According to surveys, finance staff spend an average of several hours per month on invoice verification, and manual judgment inevitably has omissions. Especially after the full rollout of fully digitalized e-invoices, invoice volumes surge, and manual modes are unsustainable. Therefore, leveraging digital tools for automatic verification has become key to reducing costs and increasing efficiency.

▍III. How does Kailing input VAT invoice management achieve automatic verification and duplicate checking?

Kailing Technology's input VAT invoice management system directly connects to the tax bureau, automatically obtains all enterprise invoice sources, and upon invoice arrival automatically completes authenticity verification and duplicate checking while synchronously performing compliance validation. The system supports batch verification without invoice-by-invoice operations, and verification results are automatically retained to form a traceable electronic ledger. At the same time, the system seamlessly integrates with Kailing AI OCR intelligent recognition; paper invoices can be photographed and uploaded for recognition and automatic verification, truly achieving "recognition is verification, verification is booking." This solution not only greatly improves efficiency, but also eliminates risks such as fake invoices and duplicate reimbursement from the source, freeing finance from tedious verification to focus on higher-value analysis work.

▍IV. In the era of fully digitalized e-invoices, how do enterprises build an invoice management closed loop?

After the comprehensive rollout of fully digitalized e-invoices, invoice management is no longer an isolated step but the starting point of business-finance-tax integration. Enterprises should build a full-process digital closed loop of "acquisition—verification—booking—archiving—filing." Kailing Technology offers a product combination including input VAT invoice management, AI OCR recognition, and electronic accounting archives to achieve automatic invoice verification, automatic voucher generation, and electronic archive filing, and connects with the tax filing system for automatic data retrieval and tax calculation. Through the Kailing electronic accounting archives system, vouchers are stored upon scanning, archived upon recognition, and bound into volumes upon association, ensuring invoice data is authentic, complete, and traceable, meeting the requirements of the Measures for the Management of Electronic Accounting Archives. Choose Kailing to make invoice verification no longer a burden but a solid defense line for compliant enterprise operations.
