An AI agent that automates invoice processing end-to-end. It reads incoming documents using vision-based OCR, extracts structured data (vendor, amount, date, line items), and checks each one against a vector database to catch duplicate payments before they happen.
Runs on a FastAPI backend that orchestrates the pipeline and writes clean records to a database. Fully tested against real invoice data, and hardened by fixing a credential-exposure issue — moved to a local embedded vector setup for better security and easier deployment.
Result: manual invoice entry replaced with a pipeline that runs unattended and only flags what needs a human.
