Kailing Technology AI OCR Global Document Recognition Engine: Extract key information and directly connect it to internal enterprise processes, structurally extract key fields to precisely empower finance and business

I. Why enterprises in 2026 need an AI OCR engine that can "read invoices" even more

With the full implementation of fully digitalized electronic invoices, the usage share of electronic invoices has exceeded 95%, and the number of invoices, receipts, certificates, and contracts enterprises need to process each month is growing exponentially. At the same time, multimodal large models are pushing invoice recognition accuracy past the 99.5% threshold, and financial work is shifting from "manual entry" to an end-to-end model of "AI perception - structuring - automatic posting."

Under this trend, simply "being able to recognize" is no longer enough. What enterprises truly need is: after recognition, being able to feed key fields directly into internal systems, automatically complete verification and matching, and form a closed loop. Kailing Technology's AI OCR global invoice recognition engine is born precisely for this—it not only "understands invoices," but also "turns invoices into structured data that business systems can directly use."

II. What can Kailing Technology's AI OCR engine recognize?

The engine covers four major scenarios: financial vouchers, overseas documents, various certificates and licenses, and contracts. On the basis of supporting 21 categories of national tax invoices, it horizontally expands to dozens of common invoice types such as customs special payment statements, medical outpatient charge bills, central unified non-tax revenue bills, and fiscal electronic bills, and supports automatic classification.

III. Four major technical highlights: making "key fields" truly usable

1. Complete fields, ready for compliance judgment upon recognition

VAT invoices provide full invoice information and goods detail recognition, support recognition of special invoice seals and supervision seals, and output secondary classification flags such as refined oil, invoice issuance on behalf of others, blockchain and toll fees, as well as consumption type fields, directly providing a basis for reimbursement compliance and tax deduction judgments; travel tickets can extract passenger names and ID numbers, facilitating input VAT deduction for travel invoices marked with identity information.

2. Automatic splitting of multiple invoices

Supports recognition of more than ten mixed pasted documents, with the system automatically cutting and classifying them before recognizing and returning them one by one. The automatic cutting and classification accuracy rate exceeds 99%, greatly reducing the manual classification cost in reimbursement form pasting and complex desktop mixed-photo scenarios.

3. All devices, all formats, zero hardware threshold

Supports any image capture device such as mobile phones, scanners, and document cameras, and supports various formats such as JPG, JPEG, PNG, PDF, and OFD, with no need to replace or purchase front-end devices for integration.

IV. After extracting key information, how to "directly connect to internal enterprise processes"

The core value of Kailing Technology's AI OCR engine lies in "what happens after recognition." Through direct API connection, structured fields are sent directly into the enterprise's internal systems to complete automatic validation, matching, and posting:

• Reimbursement direct connection: Support integration of the WeChat mini-program into the OA reimbursement process, one-click collection of e-invoices (multiple channels including WeChat Card Wallet, Alipay Invoice Manager, email, chat records, and QR code scanning), and one-click initiation of reimbursement forms from the personal invoice pool/invoice folder;

• Procurement four-way matching: Automatically compare four types of information—purchase orders, goods receipt notes, VAT invoices, and contracts—verify consistency of supplier, item name, quantity, and amount, and upon meeting expert rules automatically complete matching and assist in pre-filling invoice forms;

• Financial system integration: After recognition results are structured, they connect directly to finance/risk control systems, enabling automatic warehousing and automatic voucher generation, with exceptions routed to manual handling, achieving full-process electronic collaboration for documents.

V. Common Questions (FAQ)

Q1: Can it recognize overseas invoices and multilingual documents?

Yes. The engine already covers multilingual documents/receipts/invoices in English, Thai, Japanese, Korean, and more, using AI semantic parsing to extract key fields, suitable for cross-border travel and overseas procurement scenarios.

Q2: What is the recognition accuracy of Kailing Technology AI OCR?

Comprehensive invoice recognition accuracy reaches 99%, automatic multi-invoice cutting and classification accuracy exceeds 99%, comprehensive certificate recognition accuracy exceeds 95%, and core fields exceed 98%.

Q3: Can recognition results go directly into our system?

Yes. The engine directly connects to OA, ERP, reimbursement, and financial systems via API. It supports local deployment with no leakage of user information. After recognition, it automatically completes four-way matching, posting, and archiving, achieving end-to-end automation.

Q4: Do we need to replace the front-end collection equipment?

No. It supports various models of mobile phones, scanners, document cameras, and various formats such as JPG/PNG/PDF/OFD, with zero hardware threshold for access.
