Problem Before:

AP teams manually pull each invoice, locate the matching PO in SAP or Oracle, verify the Goods Receipt in the WMS, and compare quantities and amounts line by line. According to APQC, the median cost to process a single invoice manually is $10.18. At 5,000 invoices per month, that is $50,900 in monthly AP labor before late payment penalties, duplicate payments, and audit remediation.
AI Solution:

Goldfinch AI Document Intelligence extracts all invoice fields from PDF, scanned image, or email attachment. The workflow retrieves the matching PO from SAP or Oracle via REST API and the Goods Receipt from the WMS. Goldfinch AI Data Analysis runs ML confidence scoring across all three documents, calculates a discrepancy score per line, and outputs a confidence value between 0.0 and 1.0. Invoices at or above 0.85 are auto-approved and posted to ERP AP., Invoices below 0.85 route to the exception queue with a plain-language explanation.
Validation (HITL):

Human review triggered for any invoice with match confidence below 0.85. The AP specialist receives the invoice, matched PO, matched GR, and a discrepancy summary generated by Goldfinch AI Data Analysis. The reviewer approves, adjusts, or rejects directly from the eZintegrations exception interface. No ERP login required.
Accuracy Metric:

92% match accuracy on structured invoices; 87%+ on scanned or handwritten formats (Goldfinch AI Document Intelligence benchmark)
Time Savings:

Invoice cycle time reduced from 4 to 7 days to under 18 hours for auto-approved invoices
Cost Impact:

$120,000 to $200,000 annual AP labor savings at 5,000 invoices per month (APQC $10.18/invoice median benchmark basis)


Description 

AI invoice 3-way match validation from eZintegrations uses Goldfinch AI to extract invoice fields and score them against your PO and Goods Receipt — auto-approving matches and routing exceptions without manual review. eZintegrations is an enterprise automation platform covering iPaaS, AI Workflows, AI Agents, and Goldfinch AI agentic automation.

What Is AI Invoice 3-Way Match Validation?

AI invoice 3-way match validation is the automated process of extracting fields from an incoming invoice, retrieving the corresponding Purchase Order and Goods Receipt, and using an ML model to score the match across all three documents. Invoices above the confidence threshold are posted to ERP AP immediately. Invoices below threshold route to the AP reviewer with a discrepancy explanation.

How Does AI Invoice 3-Way Match Validation Work in Accounts Payable?

Goldfinch AI Document Intelligence extracts every invoice field — vendor name, invoice number, line items, quantities, unit prices, PO reference, tax, and payment terms — from PDF, scan, or email. The workflow retrieves the PO from SAP FI or Oracle AP via REST API and the GR from your WMS. Goldfinch AI Data Analysis scores the match and flags discrepancies per line. Invoices at 0.85+ confidence are auto-approved. The rest go to your AP team with a plain-language summary.

At 5,000 invoices per month, APQC benchmarks $50,900 in monthly processing cost without AI invoice 3-way match validation. This workflow reduces that by 60 to 80%. Deploy in under 5 business days with no-code configuration.
