Three-Way Matchnoun

Verifying a supplier invoice against the PO and the goods received before paying.

A three-way match checks three documents agree before an invoice is paid: the purchase order (what was ordered), the goods received note (what arrived) and the supplier invoice (what is billed).

It is the core control against overbilling, duplicate payments and fraud — payment is only released when quantities and prices reconcile across all three.
