How TriangleAudit works
The Triangle Audit method asks three questions: What was agreed? What was delivered? What was invoiced? TriangleAudit structures the information needed to answer them.
The Triangle Audit method
Validate what was agreed, what was delivered, and what was invoiced to ensure every charge is accurate, complete, and aligned with your terms.
Use contracts, rate cards, purchase orders, and other commercial terms, including Incoterms, duties rates and charges, tax rates, and surcharges.

| Incoterms | DAP (Delivered at Place) |

Illustrative workflow using fictional data
A fictional carrier invoice shows CAD 2,480 invoiced. The available rate and shipment information supports CAD 2,300. A CAD 180 additional freight service charge has no supporting receipt in the sample record.
The CAD 180 needs review. It is not presented as an error, overpayment, or confirmed saving.
