What is the difference between two-way, three-way, and four-way matching?

Beginner

Answer

Two-way matching compares the PO to the invoice only (used for services with no goods receipt). Three-way adds the goods receipt note. Four-way matching adds an inspection/quality certificate confirming the goods passed inspection. More match points give stronger control but require more documentation.
Real-world example Consulting fees use two-way matching, inventory uses three-way, and regulated pharmaceutical receipts use four-way with a QC inspection.
