The Problem

Manual invoice processing takes hours weekly. Data entry errors cause payment delays, and invoices pile up waiting for approval with no clear owner. There is no visibility into payment status, so finance fields the same “did we pay this?” questions over and over. The slower the cycle, the more strained the relationships with vendors who are waiting to be paid.

The Automation

n8n captures invoices from email, extracts line items and amounts using OCR, and matches them against purchase orders. It routes each invoice to the appropriate approvers and posts approved invoices directly into QuickBooks, Xero, or SAP. The workflow performs automatic three-way matching across purchase order, receipt, and invoice, so discrepancies surface before payment rather than after. Slack keeps approvers moving and gives finance a live view of where every invoice stands.

The Payoff

Automating the accounts-payable pipeline compresses the entire cycle:

  • Invoice processing drops from hours of manual entry to minutes
  • Payment cycles get shorter, keeping vendor relationships healthy
  • Data entry errors are designed out by OCR capture and matching
  • Real-time invoice tracking and status visibility
  • Automatic three-way matching across PO, receipt, and invoice

Who It Is For

This is built for finance and operations teams handling meaningful invoice volume in QuickBooks, Xero, or SAP, where manual AP is both a time sink and a source of costly errors. It is a more advanced build, well suited to teams ready to systematize accounts payable end to end.
