Field notes
Red flags that hide inside a clean three-way match
Three-way match is often treated as a finish line. Purchase order, goods receipt, and invoice align — release the payment. In Nest’s Vendor Payment Audit Studio we treat alignment as a starting hypothesis, not a verdict.
Blanket orders that never get tired
When a blanket PO absorbs months of activity, line-level agreement can look pristine while the underlying demand story drifts. Ask what the original authorization covered, and whether anyone revisits remaining value. A clean match against a stale ceiling is still a control story.
Receipts that arrive as theater
Some warehouses post receipt to unblock AP, then reconcile quantities later — or never. Your packet shows a receipt document number. It may not show whether anyone counted. Look for receipt timestamps clustered at month-end, or operators who always post full quantity on the same minute the invoice lands.
Price overlays and silent freight
Unit prices match while ancillary charges travel on a separate vendor or a miscoded GL. The three-way view on the primary line stays green. Expand the vendor’s payment history for the period: freight, tooling, and “adjustment” invoices often sit one click away from the tidy packet.
What to write down
If you escalate, name the behavior — not just “match incomplete.” Finance leads act faster when you say “receipts post without count evidence on shift B” than when you say “potential receiving risk.” That discipline is a core thread in our financial auditing guidance for vendor payment review.
