Three-way matching compares a purchase order, a goods receipt or service confirmation, and a supplier invoice before payment approval. The control checks whether the supplier billed for what the buyer ordered and actually received, within the organization's accepted tolerances.
How does Three-way matching work in practice?
The control compares the purchase order, goods receipt or service confirmation, and supplier invoice. Matching checks whether the supplier billed the approved item, quantity and price and whether the business recorded receipt. Tolerances determine which differences can pass automatically. Exceptions should be assigned and resolved before payment approval rather than hidden through manual overrides.
