Accounts Payable Automation
An AI document extraction pipeline that reads incoming invoice PDFs from an email inbox, extracts line items and totals, matches against purchase orders, routes for approval, and posts approved invoices to Xero.
Problem
A finance team was manually keying invoice data from PDFs into Xero — 12 minutes per invoice, 80 invoices a month.
What we built
An email-triggered extraction pipeline with PO matching, approval routing, and Xero posting.
How it works
- 01Invoice PDF arrives by email
- 02AI extracts line items and totals
- 03Matched against PO system
- 04Routed for approval if above threshold
- 05Posted to Xero on approval
