Three-way match is the accounts payable control that compares a supplier invoice against the purchase order and goods receipt note to verify that what was ordered, received, and billed all agree before payment is released.
Three-way matching is a foundational procure-to-pay control. Before an invoice is approved for payment, it is checked against two other documents: the original purchase order (confirming what was ordered and at what price) and the goods receipt note or service confirmation (confirming that the goods or services were actually delivered). All three documents must agree within defined tolerances for payment to proceed.
When the three-way match fails, it typically indicates one of several problems: the supplier invoiced at a different price than agreed, quantities differ from what was delivered, or an invoice has been submitted without a corresponding purchase order or delivery. Each of these represents a potential spend leakage or fraud risk.
ProcureLabs automates three-way match at scale, flagging exceptions as they arise and routing them to the appropriate reviewer rather than allowing payments to proceed by default. Its transaction-integrity engine applies statistical methods — including Benford's Law analysis — to detect unusual patterns in invoice data that rule-based matching alone might miss.
Value leakage is the gap between the savings a procurement team negotiates and the savings that actually reach the bottom line, typically caused by contract non-compliance, maverick spending, or billing errors.
Maverick spend is purchasing that happens outside of approved contracts and procurement channels, bypassing negotiated pricing and compliance controls.
Spend leakage is the unintended loss of budgeted procurement value through billing errors, payment duplicates, unclaimed rebates, and off-contract purchasing.
Contract intelligence is the use of AI to extract, analyse, and monitor commercial obligations from supplier contracts so that procurement teams can enforce terms and capture negotiated value.
Pala, the ProcureLabs AI copilot, surfaces insights about three-way match and helps your team act on them — no data science skills required.
