Frequently asked questions:

What is 3-way matching in accounts payable?

3-way matching in accounts payable is the process of comparing three documents – the purchase order (PO), goods receipt note (GRN), and supplier invoice – to confirm that what was ordered, received, and billed all align before payment.

What is PO matching?

PO matching is the process of validating supplier invoices against purchasing documents to ensure accuracy. In practice, it includes 2-way matching (PO + invoice) and 3-way matching (PO + GRN + invoice).

What is 2-way PO matching?

2-way PO matching verifies that the supplier invoice matches the purchase order – typically confirming line items, quantities, and price – without referencing a goods receipt note (GRN).

How does automated 3-way matching improve efficiency?

Automation reduces manual verification by matching POs, GRNs, and invoices automatically and flagging only the exceptions that need review. This speeds up PO invoice processing and helps teams handle higher invoice volumes without extra admin work.

What is a PO invoice in accounts payable?

A PO invoice is a supplier invoice that references a purchase order created by the buyer. It’s used for PO invoice matching to confirm the invoice aligns with the approved order (and with the GRN in 3-way matching).

What documents are involved in 3-way matching?

3-way matching uses:

Purchase Order (PO): what was requested/approved
Goods Receipt Note (GRN): what was delivered/received
Supplier Invoice: what the supplier billed

What is the difference between 2-way and 3-way matching?

2-way matching checks the invoice against the PO (quantities, pricing, terms).

3-way matching adds the GRN, confirming the goods/services were actually received before approving payment.

Why is 3-way matching important in accounts payable?

3-way matching helps ensure invoices are legitimate and accurate before payment. It reduces errors, prevents overpayments, strengthens controls, and improves compliance across PO invoice processing.

How are mismatches and exceptions handled?

When quantities, pricing, or receipt details don’t align, the transaction is flagged as an exception so AP can review and resolve mismatches quickly rather than manually checking every invoice end-to-end.

Can 3-way matching integrate with my ERP system?

Yes. Kefron AP integrates with your ERP using the best-fit approach for your environment: Standard API Connection, Kefron Konnect (encrypted file/SFTP), or Custom API Integration.
