What is Three-Way Match?
The AP control that checks a bill against what you ordered and what you actually received before paying.
Three-Way Match: definition
Before paying a bill, you want proof you ordered it, received it, and were charged the agreed amount. The three-way match compares the purchase order (what you agreed to buy), the goods receipt (what actually arrived), and the invoice (what you are being billed). A mismatch in quantity or price stops the payment for review - preventing overbilling, duplicate invoices, and fraud.
- Purchase order: the authorized quantity and price
- Goods receipt: proof of what was actually delivered
- Invoice: what the vendor is charging
- Payment releases only when all three reconcile within tolerance
How Fintra handles it
Fintra runs the three-way match inside its bill-pay workflow, tied to the GR/IR clearing account. Matching invoices flow toward payment automatically; mismatches are held and routed to a human with the discrepancy highlighted. No bill is paid outside the control, and every approval is logged as evidence under SentriAI governance.
Worked example
| Document | Quantity | Price | Total |
|---|---|---|---|
| Purchase order | 100 units | $10 | $1,000 |
| Goods receipt | 95 units | - | - |
| Invoice | 100 units | $10 | $1,000 |
Frequently asked questions
What are the three documents in a three-way match?
The purchase order (what you agreed to buy), the goods receipt (what was actually delivered), and the vendor invoice (what you are charged). Payment is authorized only when the quantities and prices across all three reconcile within tolerance.
Why is three-way matching important?
It prevents paying for goods you did not receive, being overcharged, or paying duplicate and fraudulent invoices. It is one of the most effective controls in accounts payable and a common audit expectation.
What is the difference between two-way and three-way matching?
A two-way match compares only the invoice and purchase order. A three-way match adds the goods receipt, confirming the items were actually delivered - stronger control, essential when you receive physical goods.
Does Fintra automate three-way matching?
Yes. Fintra matches invoices against POs and receipts automatically inside bill pay, clears the GR/IR account on a match, and routes mismatches to a human with the discrepancy flagged - logging each approval as governance evidence.
