The three documents in a three-way match

Three-way matching compares a purchase order, receiving information, and supplier invoice to help AP teams review whether an invoice aligns with what was ordered, received, and billed.

Tolerances, exceptions, and workflow design

Organizations set their own review rules and tolerance thresholds. When quantity, price, timing, or documentation does not align, an exception workflow can route the issue to procurement, receiving, AP, or the supplier for resolution.

Automation can help organize matching and exception review, but matching configurations, source data, and approval steps vary by ERP environment and organization.
