3-Way Matching in Accounts Payable is a verification process that compares three documents before paying suppliers: the purchase order, supplier invoice, and goods receipt. This control mechanism ensures companies only pay for goods they ordered, received, and were billed correctly for at the agreed price.

How does 3-Way Matching in Accounts Payable Work?

The 3-way matching process validates information across three key documents to prevent payment errors and fraud. Finance teams compare details like quantities, prices, and descriptions to ensure everything aligns before approving payment.

The matching process follows these steps:

1. Purchase Order Review: Checking what was originally ordered
2. Invoice Comparison: Verifying the supplier’s billing details
3. Receipt Validation: Confirming what was actually received
4. Discrepancy Resolution: Addressing any differences found
5. Payment Approval: Authorizing payment once everything matches

Why is 3-Way Matching in Accounts Payable so important?

This process protects companies from overpayments, duplicate invoices, and fraudulent billing. A manufacturing company ordering $50,000 in raw materials can catch billing errors before losing money. 

Without proper matching, businesses risk paying for goods never received or at incorrect prices.

Components of 3-Way Matching

Purchase Order (PO):

• Order Details: Items, quantities, and agreed prices
• Vendor Information: Supplier details and delivery terms
• Authorization: Approved spending and budget allocation

Supplier Invoice:

• Billing Information: Charges, taxes, and payment terms
• Line Items: Detailed breakdown of goods or services
• Reference Numbers: PO numbers and delivery confirmations

Goods Receipt:

• Delivery Confirmation: What was actually received
• Quality Check: Condition and specifications of delivered items
• Quantity Verification: Actual amounts received vs. ordered

Common Discrepancies:

• Price Variations: Invoiced amounts different from PO prices
• Quantity Differences: Receiving more or less than ordered
• Missing Items: Invoices for undelivered goods

Types of Matching Processes 

Manual 3-Way Matching involves staff physically comparing paper documents. This approach works for small invoice volumes but becomes time-consuming as businesses grow.

Automated 3-Way Matching uses software to compare digital documents and flag discrepancies. This method processes invoices faster and reduces human error while maintaining accuracy.

Exception-Based Matching automatically approves invoices that match perfectly and routes only discrepancies to staff for review. This hybrid approach balances efficiency with control.
