The challenge

The finance team was typing supplier invoices into the accounting system by hand — slow, error-prone, and impossible to scale as volumes grew.

Our solution

We built a pipeline that ingests invoices from email and uploads, runs OCR plus AI extraction to capture header fields and line items, validates GST numbers and totals, detects duplicates, and posts approved entries to the accounting system. Low-confidence documents go to a review queue.

Key features

  • Email and bulk-upload ingestion
  • Header and line-item extraction
  • GSTIN, totals and duplicate validation
  • Human review queue for low-confidence fields
  • Export to accounting / ERP
  • Audit trail for every document

Tech stack

  • Python
  • OCR
  • LLM extraction
  • PostgreSQL
  • React
