A 2-way match is a verification process used in financial systems where two documents, the purchase order and the vendor's invoice, are compared. The quantities and amounts on the vendor's invoice are cross-checked against the corresponding information on the purchase order. If they align and match, the invoice is considered valid for payment.

This simplified matching method is commonly employed when there is no need to verify the receipt of goods or services through a receiving report. The 2-way match helps ensure accuracy in invoice processing and assists in preventing errors or discrepancies in financial transactions.
