AI Invoice Processing Software is a self-hosted, full-stack application that automates invoice data extraction from PDFs, images, and scanned documents. You get complete source code with two processing engines: a fast pattern-based system (75-85% accuracy) and an AI-enhanced version using real transformer models—LayoutLMv3 and Donut—achieving 90-95% accuracy on standard invoices. The system handles multi-format uploads, extracts vendor details, line items, amounts, dates, and tax information, then validates the data against business rules. It includes user authentication, batch processing, a responsive dashboard with analytics, and CSV export capabilities.
 
This solution is built for small to medium businesses, accounting firms, and enterprises that process invoices at scale and want to eliminate manual data entry. You can deploy it on your own infrastructure via Docker, modify the code to fit your workflows, and operate it as an internal tool or commercial SaaS offering under the perpetual license included. The AI models run entirely on your servers—no external API calls, no data leaves your environment. You may fine-tune the included transformer models on your own invoice templates to improve accuracy further. The system uses synthetic data generation during development to improve model coverage and protect real user information during testing.
 
Requirements: 4-8GB RAM minimum (8-16GB recommended for AI version), Docker, and basic technical knowledge to deploy and configure. Processing speed ranges from 1-3 seconds per invoice (pattern-based) to 3-10 seconds (AI with CPU) or 2-5 seconds (AI with GPU). The application supports PostgreSQL for data storage and Redis for caching. You receive all backend Python code (FastAPI), frontend React/TypeScript code, Docker configurations, deployment scripts, comprehensive documentation, and pre-trained AI models. No recurring fees, no subscriptions—one-time purchase grants perpetual use and modification rights for your own business.
 
IMPORTANT NOTE: This application has been fully developed with all features implemented. However, it has not been tested in a live production environment. Buyer should expect to perform integration testing and may encounter minor bugs that require fixing. Basic technical knowledge and development skills are required.
 
NO REFUNDS: Due to the digital nature, all sales are final.
