# Invoices

Match supplier invoices against the PO and goods receipt before payment.

An **Invoice** is the supplier's bill for a completed delivery. ProcureFlow runs a three-way match, comparing the invoice against the [Purchase Order](https://www.procureflow.ai/docs/purchase-orders.md) and the [Goods Receipt](https://www.procureflow.ai/docs/goods-receipt.md), so you only pay for what was ordered and received.

For buyer-managed suppliers, you upload the invoice yourself. An assigned approver then confirms the match, or reports a mismatch if the numbers do not line up. You resolve any flagged mismatch in the three-way match drawer. Once an invoice is approved, it becomes payable and Finance settles it in a [payment run](https://www.procureflow.ai/docs/finance.md).
