What is freight audit and payment?

The Short Answer

Freight audit and payment (FAP) is reviewing every carrier invoice for accuracy against your contracted rates before you pay it, then managing payment and cost allocation.

Carriers bill fast and they bill often, and a meaningful share of those invoices contain errors: wrong rates, invalid accessorials, duplicate charges, and reclasses that do not hold up. A freight audit catches those before the money goes out the door. Payment and allocation then make sure each charge is paid once, coded correctly, and visible in your reporting.

What Gets Audited

Six things every invoice should be checked against.

• Rate vs contract. Does the billed rate match the rate you negotiated for that lane and service level?
• Accessorials. Were liftgate, detention, residential, and other charges actually incurred and valid? Accessorials are the most disputed line on a freight bill.
• Weight and class. If the carrier reweighed or reclassed, does the freight class change hold up, or is it disputable?
• Duplicate billing. Was the same shipment invoiced twice, a common and costly error?
• Fuel surcharge. Is the fuel percentage correct for the billing period?
• Mileage and routing. Was the shipment billed on the correct distance and route?

The Process

From invoice to paid, step by step.

• Capture. Collect every carrier invoice in one place, ideally via EDI or API rather than email and PDFs.
• Match. Tie each invoice to the original shipment, BOL, and contracted rate.
• Audit. Check the six items above and flag any discrepancy.
• Dispute. Short-pay or dispute invalid charges with the carrier, with documentation.
• Approve and pay. Release correct invoices for payment, once, on terms.
• Allocate. Code each charge to the right GL account, customer, or cost center.
• Report. Roll the data up into spend visibility by lane, mode, and carrier.

Common Mistakes

Five ways shippers overpay.

• Not auditing at all. Paying invoices on trust. Every uncaught error is pure margin lost.
• Paying duplicates. Without matching to the shipment, the same load gets paid twice.
• Accepting accessorials blindly. Liftgate and detention charges that never happened still get paid when no one checks.
• Never disputing reclasses. Carriers reclass and rebill; many of those are disputable with the right weight and inspection documentation.
• No cost allocation or visibility. When freight cost is not coded and reported, you cannot see where the money goes or negotiate from data.

Manual vs Managed

Why most shippers do not audit every invoice.

Auditing every freight bill by hand is slow, and most lean shipping teams simply do not have the time, so invoices get paid unaudited. The alternative is a managed program where capture, matching, audit, dispute, payment, and allocation run on purpose-built technology with people accountable for the outcome. The audit happens on every invoice, not the few someone has time to spot-check.
