What Is Three-Way Matching? Why It Fails for Service Invoices
Three-way matching compares POs, goods receipts, and invoices. It works for goods. For services — freight, maintenance, contract labor — it structurally cannot work. Here’s why.
Three-way matching is the foundational accounts payable control used by every manufacturer. It compares three documents before approving payment: the purchase order (what was ordered), the goods received note (what was delivered), and the invoice (what the vendor is charging). If all three agree within tolerance, the payment is approved. If any disagree, an exception is generated.
