Kailing Technology Overseas Invoice Intelligent Processing: Non-fixed layout overseas invoice/bill OCR + AI semantic parsing + intelligent review

I. Industry Background: New Invoice Processing Needs in Cross-Border + Domestic Dual Scenarios

Driven by both digitalization and globalization, the proportion of cross-border business continues to rise, and the number of international invoices/receipts generated by overseas travel, procurement, and government affairs liaison has grown substantially. Such documents have problems such as complex layouts, many languages, and no unified format standards; at the same time, in domestic financial processing, compliant recognition of invoice supervision seals, special invoice seals, and contract seals is a core requirement for enterprise tax filing and voucher archiving, and the completeness of seal information extraction directly affects financial compliance.

Under the traditional processing model, international invoices require dedicated staff to manually enter information against multilingual rules, resulting in low efficiency and high error rates; invoice seal recognition relies on manual verification, making it easy to miss key information. Enterprises face the dual challenges of low cross-border financial processing efficiency and high domestic invoice compliance review risks. Against this background, Kailing Technology leverages OCR recognition engines, multimodal models, and large language model technology to build an integrated solution for intelligent recognition of international invoices + invoice seals, precisely matching enterprises' core needs of "efficient cross-border processing and local compliance verification," becoming a key lever for enterprise financial digital upgrading.

II. Technical core: intelligent recognition technology path with full-process closed loop

Kailing Technology's solution abandons traditional template matching and manual verification models, forming a full-process closed loop of "collection - recognition - extraction - verification - output" through five core technical actions, while adapting to the recognition difficulties of both international and domestic invoices:

1. Multi-scenario image collection: supports collection through scanners, mobile terminals and other channels, converting paper bills into electronic images, compatible with multiple file formats such as jpg, png, PDF, OFD, adapting to the full-scenario collection needs of enterprise offline paper bills and online electronic files/screenshots;

2. Intelligent image preprocessing: complete image correction and noise reduction optimization through self-developed algorithms, solving issues such as document wrinkles, tilt, blurry shooting, stains, and scratches, while supporting layered recognition of multilingual text and seal patterns, laying a solid foundation for subsequent information extraction;

3. Dual-model intelligent data extraction: Define field information by business scenario classification, adopt a dual-mode combination of official model (general invoices) + custom model to intelligently classify and extract information from international invoices, and uniformly convert the currency corresponding to the amount into international currency codes to achieve standardized processing;

4. Collaborative verification of invoices + seals: Simultaneously complete content recognition and seal information extraction for domestic invoices, relying on a dedicated invoice recognition engine to verify core compliance information of the special invoice seal and supervision seal, and supplement uncovered seal information through model training;

5. Output empowered by large language models: using a trained large model for document recognition to achieve multilingual translation of document content, standardized field output formats, and conditional extraction of content, while returning recognition results through standardized API interfaces for seamless connection with enterprises' existing financial systems.

III. Kailing Technology's core capabilities, solving overseas invoice processing challenges

Kailing Technology's solution focuses on the core needs of enterprises and builds core capabilities for intelligent recognition of international invoices/receipts. Verified by actual sample testing, core information can be accurately extracted, and uncovered capabilities can be quickly completed through model training, fully adapting to enterprise financial processing needs.

1. Full coverage of multiple languages and multiple invoice types: supports recognition in multiple languages such as French, Korean, Vietnamese, Japanese, Portuguese, Mexican Spanish, Russian, German, etc., covering multiple invoice types such as Korean taxi receipts/accommodation invoices, Singapore ride-hailing screenshots/restaurant receipts, Czech consulate fee receipts, Mexican consulate official government receipts, adapting to full scenarios such as cross-border travel, procurement, and government affairs connection;

2. Dual-model precise extraction: general international invoices are extracted using the official model, while special types of invoices are recognized through custom models. After sample testing, key information was correctly extracted from all test samples, including Korean taxi receipts, Singapore ride-hailing screenshots, and Mexican Spanish-language official receipts, achieving industry-leading extraction accuracy;

3. Currency and field standardization: Automatically convert the currencies corresponding to the amounts in the documents into international currency codes, solving the basic challenge of cross-border financial currency conversion; at the same time, standardize field output formats through large language models, support enterprises in setting conditional extraction rules based on business needs, and adapt to personalized financial processing needs;

4. Rapid construction of custom models: A custom model management and training platform is provided. Enterprises can add special invoice types based on their own business, quickly complete sample annotation training and data extraction model construction, and achieve "wherever business expands, recognition capability covers."

IV. Core advantages: multi-dimensional differentiated technology and service competitiveness

Advantage 1: Dual-model flexible adaptation, solving the dual challenges of "format + language" in international invoices

In response to the core pain points of international invoices being "complex in format, numerous in language, and one format per invoice," Kailing Technology adopts a dual-mode strategy combining official models and custom models. There is no need to preset format rules in advance. General invoices can be quickly recognized through official models, while special invoices can be quickly built through a custom model management training platform, adapting to multiple countries and multiple invoice types such as South Korea, Singapore, the Czech Republic, and Mexico. At the same time, it combines large language models to achieve multilingual translation and field standardization, fundamentally solving the format and language barriers in international invoice recognition.

Advantage 2: Integrated invoice + seal recognition, achieving full-scenario financial coverage for "cross-border + domestic"

Unlike a single invoice recognition solution, Kailing Technology builds an integrated solution of international invoice extraction + domestic seal verification, meeting both enterprises' multilingual invoice processing needs for cross-border business and domestic finance's invoice seal compliance review needs, achieving full-scenario adaptation for enterprises' "cross-border financial processing, local voucher archiving," avoiding the cumbersome process of connecting multiple systems, and reducing digitalization costs.

Advantage 3: Multi-scenario collection + lightweight integration, greatly lowering the threshold for enterprise implementation

- Multi-scenario collection adaptation: supports collection through scanners, mobile devices, OCR recognition engines, and other channels, is compatible with multiple file formats such as jpg, png, and PDF, and adapts to collection needs for all types of documents including paper invoices, electronic files, and mobile screenshots, without requiring changes to existing collection processes;

- Lightweight system integration: provides plug-and-play standardized API interfaces, accompanied by detailed development documentation and parsing methods. Enterprises can quickly connect recognition results to existing financial systems without building a professional AI team, achieving seamless connection from "collection-recognition-output";

- Rapid model training: the custom model management and training platform supports rapid sample annotation and model building; for uncovered languages or invoice types, model training can be completed quickly, while uncovered seal recognition capabilities can be trained after evaluation by professional trainers, responding to enterprises' personalized needs.

Advantage 4: Verified by actual samples, with real and implementable recognition results
