Overview
Automated invoice processing pipeline using n8n — extracts invoice data via OCR, validates against PO records, routes for approval, and syncs with QuickBooks.
The Challenge
Finance team manually processed 500+ invoices weekly with 15% error rate. Needed automated extraction, validation against purchase orders, and multi-level approval routing.
Our Solution
Built n8n workflow: Email trigger → AI OCR extraction → PO matching → approval routing (Slack) → QuickBooks sync → notification. Human-in-loop for exceptions only.
The Result
98% automation rate, 99.5% extraction accuracy, reduced processing time from 4 days to 4 hours, saved $120K/year in manual processing costs.
