Definition & Explanation

Internal freight audit procedures are designed to catch overbilling, duplicate charges, and incorrect surcharges before invoices are paid. Invoice data is systematically cross-referenced against shipment orders, proof-of-delivery records, and contracted rate schedules to surface discrepancies in weights, rate categories, or unauthorized accessorial fees. Shippers, forwarders, and logistics providers rely on these procedures when transportation volumes or complex carrier agreements make invoice-by-invoice manual review impractical. Unlike outsourced freight audit services, the process remains entirely in-house—preserving data control but requiring dedicated internal capacity. A functioning procedure depends on a defined matching workflow between accounts payable and shipping data, whether manual or TMS-automated.
