Invoice Three Way Match

Invoice Three Way Match is a crucial process in the field of finance and accounting, specifically related to the verification and validation of invoices in a company’s accounts payable function. This process involves comparing three essential documents: the purchase order, the receiving report, and the supplier’s invoice. The objective of the Invoice Three Way Match is to ensure that the amounts and details appearing on all three documents agree and are accurate.


In today’s complex business environment, where companies engage in numerous transactions with multiple suppliers, ensuring accurate invoicing is of utmost importance. The Invoice Three Way Match is a systematic approach employed by organizations to mitigate the risk of errors, fraud, and discrepancies in their financial records. By conducting a three-way comparison, businesses can maintain financial integrity and establish robust control over their payables process.


The first document in the Invoice Three Way Match process is the purchase order (PO). A purchase order is an official document issued by a buyer to a supplier, outlining the details of goods or services required. During the Invoice Three Way Match, the PO serves as the reference document to ensure that the items or services received match those ordered.

The second document is the receiving report. This document, sometimes referred to as the goods receipt or GRN, verifies that the products or services listed on the PO have been received in full and are in good condition. The receiving report is often prepared by the receiving department or warehouse personnel and acts as crucial evidence in the three-way reconciliation.

The final document is the supplier’s invoice. The supplier generates the invoice, deducting any agreed-upon discounts or promotions. The invoice must reflect the accurate pricing and quantities for the received goods or services. The Invoice Three Way Match involves cross-checking the supplier’s invoice against the PO and receiving report to ensure consistency.

Verification Process:

During the verification process, the Invoice Three Way Match focuses on three key aspects: quantities, prices, and terms. It is essential to confirm that the quantities of the items received correspond with those stated on the PO. Any discrepancies may indicate potential issues, such as misunderstood orders, delivery failures, or invoicing errors.

Furthermore, the prices listed on the supplier’s invoice should align with those specified on the PO. Any disparities may require further investigation and corrective action. Additionally, the terms of the transaction, such as payment due date, payment method, and any applicable discounts or rebates, must match the agreed-upon terms.


Implementing the Invoice Three Way Match process offers significant benefits to companies. Firstly, it enhances accuracy and reduces the risk of errors and fraud within the accounts payable function. By reconciling these essential documents, businesses can identify and rectify discrepancies promptly, preventing potential financial losses and ensuring precise financial reporting.

Secondly, the three-way comparison helps maintain strong supplier relationships. By promptly identifying and addressing any issues, businesses can avoid payment delays and resolve discrepancies smoothly, fostering trust and collaboration with their suppliers.

Moreover, the Invoice Three Way Match process improves financial efficiency. Clear communication and accuracy in the invoicing process allow for faster payment processing, reducing the cycle time and optimizing cash flow management.


Invoice Three Way Match is a vital process in finance and accounting, facilitating the validation and verification of invoices against purchase orders and receiving reports. By conducting a three-way comparison, organizations can ensure accuracy, prevent fraud, and maintain robust control over their payables process. This diligent verification process mitigates financial risks, strengthens supplier relationships, and increases financial efficiency, making it an indispensable practice in today’s business landscape.
