What Is a Three Way Match in Accounts Payable?

A three-way match in accounts payable is a verification process within financial operations. This method ensures a company only pays for goods or services legitimately ordered and received. It involves comparing information across three distinct documents to confirm a transaction’s accuracy and validity before payment is released. This approach helps maintain financial control and prevent inaccuracies in an organization’s expenditures.

Core Components of the Match

The three-way match relies on the alignment of specific details found in three primary documents. The first is the Purchase Order (PO), an official document created by the buyer and sent to a supplier to initiate a purchase. A PO serves as a formal commitment outlining the specific products or services to be acquired, including quantities, agreed-upon prices, delivery details, and payment terms. It acts as a legally binding document once accepted by the supplier, setting clear expectations for both parties.

The second component is the Goods Receipt (GR), also known as a Receiving Report. This internal document is generated by the buyer’s receiving department upon arrival and inspection of ordered goods or services. A GR confirms what was actually received, noting the quantity, condition, and sometimes the quality of items against the original purchase order. It serves as proof of delivery, documenting the receipt of items before any payment is authorized.

The third document is the Vendor Invoice, a formal request for payment issued by the supplier to the buyer. This invoice details the goods or services provided, including an itemized list with quantities, unit prices, and the total amount due. It also specifies payment terms, such as the due date and accepted payment methods. The vendor invoice prompts the buyer’s accounts payable department to process the payment.

The Matching Process

The three-way matching process compares the Purchase Order, Goods Receipt, and Vendor Invoice to ensure consistency across the transaction. This comparison begins by verifying that the vendor invoice corresponds to an authorized purchase order. Key data points, such as the purchase order number, item descriptions, quantities, and prices, are cross-referenced between these two documents.

Once the invoice and purchase order align, the process extends to include the goods receipt. The quantities and descriptions of items listed on the invoice are then compared against items documented as received on the goods receipt. This step confirms the company is being billed only for what was ordered and successfully delivered. Any discrepancies, such as differences in quantity, price, or item specifications, are identified during this comparison.

If a mismatch occurs, the invoice is flagged and placed on hold, preventing immediate payment. Accounts payable personnel then investigate the discrepancy, which may involve contacting the purchasing department, receiving department, or the vendor to resolve the issue. Resolution could entail adjusting the invoice, requesting a credit memo from the vendor, or clarifying order details. A successful three-way match, where all details across the PO, GR, and invoice agree, signals the transaction is valid and authorizes payment processing.

Significance in Accounts Payable

The three-way match serves as an internal control within accounts payable, ensuring financial accuracy for organizations. By requiring verification across multiple documents, it helps confirm payments are only made for goods and services properly procured and received. This verification prevents overpayments, duplicate payments, or payments for incorrect items, safeguarding company funds.

This process also acts as a deterrent against fraud and errors. It establishes a checks-and-balances system that makes it more difficult for fraudulent invoices to be processed, whether from external parties or internal collusion. The comparison helps uncover unintentional human errors in data entry or discrepancies arising from miscommunications between departments or with suppliers. Implementing this control reduces financial risk by validating each transaction before funds are disbursed.

The three-way match creates an audit trail for every purchase and payment. The documented alignment of purchase orders, goods receipts, and vendor invoices provides clear evidence of financial due diligence. This detailed record is useful during internal or external audits, demonstrating adherence to established procurement and payment policies. It contributes to reliable financial reporting by ensuring expenses are accurately recorded only after proper validation.
