Kailing Technology's input VAT invoice solution deeply integrates OCR recognition with automatic duplicate checking and authenticity verification to achieve a business-finance-tax data closed loop

Today, with fully digitalized e-invoices being comprehensively advanced and China Golden Tax Phase IV deeply implemented, enterprises' input VAT invoice management is facing unprecedented changes. Traditional invoice collection and processing models are inefficient and error-prone, making it difficult for enterprises to cope with compliance and risk control challenges across all invoice types and scenarios. How to build an efficient, accurate, and closed-loop input VAT invoice management system has become a core topic in enterprise business-finance-tax digital transformation.

With deep insights into the field of business-finance-tax digitalization, Kailing Technology deeply integrates business, finance, and tax processes, committed to building enterprises a full-chain, intelligent, closed-loop management platform from invoice collection to bookkeeping and archiving.

I. Intelligent collection: OCR recognition technology solves the challenge of entering all invoice types

The solution first tackled the invoice "entry gate." Facing VAT special invoices, general invoices, electronic invoices, train tickets, taxi tickets, toll invoices, customs payment certificates, and even overseas receipts,Full categoryFor invoices, traditional manual entry or single-format recognition is no longer enough.

1. All invoice type coverage

Can automatically classify and accurately recognize dozens of invoice types including national tax invoice types, local invoice types, and other common documents, with industry-leading accuracy.

2. Multi-scenario adaptation

Supports multiple collection methods such as mobile photo capture, batch scanning with scanners, WeChat card package/chat record import, email capture, and batch folder upload, seamlessly adapting to various scenarios such as employee reimbursement and corporate payments.

3. Structured output

It not only extracts key fields such as header, amount, and tax amount, but also accurately identifies invoice details,Sealand other information, laying a solid foundation for subsequent tax deduction and compliance verification.

▶ Through OCR technology, we instantly transform disorganized paper and electronic documents into standard, structured data, completing the "first step" of intelligent finance and tax data.

II. Real-time risk control: automatic duplicate checking and authenticity verification build a compliance firewall

Invoice data collected must undergo strict risk verification before it can enter the enterprise financial system. Our solution moves risk control forward and automates it:

1. Millisecond-level automatic duplicate checking

The system automatically compares historical data in the invoice pool. When the same invoice is submitted again for reimbursement, it is immediately intercepted by the system with a prompt, fundamentally eliminating duplicate reimbursement.

2. Multi-dimensional automatic authenticity verification and rule verification

Direct Connection to the invoice verification platform of the State Taxation Administration for real-time verification of invoice status. At the same time, multiple risk verification rules are embedded:

• Basic compliance validation: verify whether information such as invoice title and tax ID is accurate.

• Blacklist control: customize product blacklists and seller blacklists to intercept non-compliant invoices from the source.

• Logical verification: implement consecutive invoice number verification, taxi same license plate number verification, passenger identity verification for passenger transport invoices, etc., to identify potential risks.

• Status monitoring: Even if an invoice has been reimbursed and recorded, the system continues to monitor its status. Once an upstream supplier illegally voids or reverses it, causing the invoice status to become "abnormal" or "out of control," the system will issue a real-time warning and notify finance personnel to promptly transfer out input tax, avoiding tax risks.

▶ High-precisionOCR recognition ensures the "accuracy" of data, while automatic duplicate checking and verification ensures the "compliance" of the process. The deep integration of the two forms an unbreakable security line for input VAT invoice management.

III. Business-finance-tax integration: achieving full-process data closed loop

A true solution goes beyond single-point efficiency gains and lies more in breaking down data silos and achieving process connectivity. Kailing Technology's input VAT invoice solution aims to build a complete business-finance-tax data closed loop:

1. Deep integration with business systems

Through standard API interfaces, the solution can seamlessly connect with front-end business systems such as OA, expense control, procurement, and ERP. When employees submit reimbursement or corporate payment applications, they can directly call identified invoices from their personal invoice folder, and the application form automatically populates the amount and tax amount, achieving "zero entry" of reimbursement data.

2. Tax Treatment Automation

◦ One-click authentication and deduction: finance personnel can batch-filter reimbursed and booked input VAT special invoices across company entities within the platform, completing selection and authentication in one click without frequently logging into multiple electronic tax bureaus.

◦ Intelligent deduction calculation: For passenger transport service invoices (such as flight and train tickets), the system automatically calculates the deductible input tax amount based on tax policies and generates the Passenger Transport Service Deduction Statistics Table, greatly simplifying filing preparation.

3. Intelligent archiving and data accumulation

Strictly comply with the Ministry of Finance's accounting archive management requirements (Cai Kuai [2020] No. 6). While completing reimbursement and payment, the system automatically archives and stores invoice source files in PDF, OFD, and XML formats, meeting the compliance requirements for electronic accounting vouchers. All process data—from collection, verification, approval, and payment to certification, posting, and archiving—is traceable in the platform, forming a complete audit trail that supports retrieval and inquiry at any time.

Kailing Technology's input VAT invoice automated management solution takes "intelligent recognition" as the starting point, "automatic risk control" as the safeguard, and "data closed loop" as the endpoint, deeply integrating OCR with duplicate checking and authenticity verification technology. It not only greatly improves the work efficiency of finance staff, but also fundamentally strengthens enterprises' internal control compliance and tax risk prevention capabilities.
