The Invoice Processing Pipeline
Invoices go from inbox to approved and paid without manual data entry
How It Works
Every incoming invoice, whether via email, supplier portal, or upload, flows through the Invoice Processing Pipeline. An AI extraction layer pulls header and line item data, matches the invoice to the corresponding purchase order or vendor contract, and validates the amounts. Matched invoices within approval thresholds post to the accounting system automatically. Discrepancies and new vendors route to a human approver with full context pre-loaded.

Implementation Notes
Invoice ingestion connects to a monitored shared inbox via Gmail or Outlook API, an upload portal for vendor self-service, and EDI or supplier portal integrations where available. Extraction handles PDF, image, and XML invoice formats with extraction accuracy above 97 percent for standardized vendor formats after calibration. Extracted fields include: vendor name, invoice number, invoice date, due date, line items with description and amount, subtotal, tax, and total. PO matching checks vendor name, PO number reference, and line item amounts against open PO records with a configurable tolerance (default 2 percent for rounding). Contract matching validates invoiced amounts against master service agreement rates for recurring vendors. Three routing tiers: auto-approve and post for matched invoices under a configured threshold (default $5,000) from approved vendors; route to department head for matched invoices above the threshold; route to finance team for any unmatched invoice, new vendor, or discrepancy. Approval workflows run in the accounting system (QuickBooks Online, NetSuite, Xero, or Bill.com) or via Slack approval messages with direct posting integration. Full audit trail maintained for every invoice. Prerequisites: a vendor database with at least 80 percent of invoices from known vendors and an accounting system with API write access.
