Three-way match

A three-way match is a control that lines up three documents — the purchase order, the goods-received note, and the supplier invoice — and only clears an invoice for payment when all three agree on what was ordered, what arrived, and what’s being billed.

How it works

• The purchase order says what you agreed to buy, and at what price.
• The receiving record says what actually turned up.
• The invoice says what the supplier wants paid.

If the three line up, the invoice is approved. If the quantity or price drifts on any of them, it’s held for a human to look at rather than paid on trust.

Why it matters

Most overpayment isn’t fraud — it’s a quiet mismatch. A supplier bills for ten units when eight arrived, or slips in last year’s rate. Without a match, those slide straight through accounts payable and you find out at year-end, if at all. The three-way match is where the leak gets caught before the money leaves.

How Fynex does it

Fynex’s AI invoice checks read every incoming invoice for duplicates, errors, and rate drift, and flag the ones that don’t reconcile against what you agreed to pay. Cleared invoices post back to the books as a journal entry, so an unmatched transaction surfaces on its own instead of hiding in the ledger. See reconciliation.
