Invoice Matching

The process of comparing an invoice against supporting documents to verify accuracy before payment.

Definition

Invoice matching is the AP control process of comparing a vendor invoice to related documents such as purchase orders, goods receipts, and contracts. The goal is to verify that the invoiced amounts, quantities, and terms are correct before authorizing payment.

Why It Matters

Invoice matching prevents overpayment, catches billing errors, and detects fraud. Without matching, companies rely on manual review alone, which is slow, inconsistent, and error-prone.

Examples

2-way match for services

A consulting invoice is matched against the PO to verify the rate and hours billed are correct.

3-way match for goods

A supplier invoice is matched to the PO and warehouse receipt to confirm quantities ordered, delivered, and billed all agree.
