A freight bill audit is the process of reviewing carrier invoices to confirm that freight charges match the agreed rates, shipment details, contracts, accessorial fees, and services actually provided. It helps shippers identify overcharges, duplicate invoices, incorrect weight or class charges, fuel surcharge errors, detention fees, and other billing discrepancies. Freight bill audits improve cost control, support better carrier management, and help businesses avoid paying inaccurate logistics charges.
