Freight Invoice Audit: Finding Charges That Should Not Be There

Line by line against the quotation and the shipment documents. Confirm the invoice matches a shipment you have, check the rated basis first, compare each charge against the contract, look for duplicates under different descriptions, verify surcharge percentages, reconcile time-based charges against gate records, and recompute the arithmetic. The total is the last thing to look at, not the first.

Duplicate charges billed under two different descriptions, surcharges at an unagreed percentage, the wrong rated basis — per container instead of per shipment, or the wrong chargeable weight — charges for services never rendered, and demurrage billed on an incorrect day count or with tiers applied retroactively.

Any charge beyond the base freight for a service performed in connection with the movement — terminal handling, documentation, chassis, waiting time, storage, inspection, special equipment. They are legitimate when the service was rendered and provided for in the contract, and they are where most billing disputes originate.

It depends on the jurisdiction and the contract, and the window is frequently short. In the United States, demurrage and detention billing rules give the billed party a defined period to request mitigation or waiver. Elsewhere the service contract or carrier terms govern. Diarise the deadline the day the invoice arrives, before you investigate.

Generally no. Rejecting an entire invoice over one charge delays every legitimate line, and where the contract requires payment of undisputed amounts it can turn a billing question into a payment default. Identify the specific line, state the amount questioned, attach evidence, and pay the remainder.

Verify the percentage against the contracted basis and confirm what base it applies to — a fuel surcharge on base freight is a different amount from one on the invoice subtotal. Then check whether the contract provides for it at all. A surcharge at a plausible-looking percentage that was never agreed is still an unauthorised charge.

The discharge or availability record, the gate-out record, the applicable tariff with its free time and tier structure, and the day-count convention. Reconstruct the calculation yourself and compare — most demurrage disputes turn on the start event, whether the first day counts, or retroactive tier application rather than on the rate.

Sometimes, subject to contractual and statutory limitation periods and to the carrier's willingness. Recovery becomes progressively harder as evidence ages and the people involved move on. The realistic conclusion is that prevention and prompt auditing are worth far more than retrospective recovery projects.

It depends on volume. Providers bring charge-code knowledge and scale, and typically charge a percentage of recoveries or a per-invoice fee. Below a certain volume the economics do not work, and structured extraction of your own charge lines gives you most of the visibility at a fraction of the cost. Above it, the specialist knowledge is genuinely valuable.

Patterns invisible on a single invoice become obvious across a hundred. A charge appearing on 30 per cent of shipments is either a legitimate conditional charge you should be quoting for, or a systemic billing error worth a single conversation rather than a hundred disputes. Both outcomes are worth having.

Because they are frequently not quoted. A rate covering the ocean leg says nothing about destination terminal handling, deconsolidation, delivery order fees or storage — and on collect or ex-works terms those land on a consignee who never saw the quotation. Ask for the destination schedule in writing before booking.

It turns the invoice into structured charge lines with description, basis, rate, quantity and amount, so the comparison against a quotation is direct rather than requiring figures to be dug out of a PDF. Grouping the invoice with the transport document and booking gives every rated line something to be checked against.
