Transportation cost control
A freight invoice can be mathematically correct and still charge the wrong shipment, weight basis, lane or accessorial service. A useful audit rebuilds the movement from the accepted quote through delivery, then asks for evidence wherever the bill departs from that baseline.
Direct answer
Audit a freight invoice before payment by connecting four records: the accepted rate or quotation, the booking confirmation, the transport document and the carrier or forwarder invoice. First verify invoice identity, shipment references, currency, billing party and duplicate status. Then normalize the movement: origin, destination, mode, service level, container or package count, chargeable weight or volume, equipment and delivery milestone. Recalculate the contracted base rate using the agreed rate basis and validity date. Review fuel, terminal, handling, customs-service, storage, demurrage, detention, redelivery, address correction and other accessorials one by one. For each extra, require the applicable rate, the triggering event, service date, responsible party and operational evidence. Keep pass-through charges separate from provider fees and do not treat a vendor spreadsheet as proof of a third-party cost. Compare credits and prior bills to prevent duplicate recovery. Code each variance, place only the disputed amount on hold when the agreement allows, send a documented query and record the final credit, rebill or approved exception. Close the audit with the paid amount, approver and immutable shipment packet.
Use this before requesting a quotation
Collect the accepted quote or rate card, booking, purchase-order or shipment reference, commercial invoice, packing list, bill of lading or air waybill, pickup and delivery evidence, customs or terminal records, prior invoices and credits. Record document revisions and responsible parties. One invoice covering several shipments should be split by shipment reference so a valid charge on one movement cannot hide an error on another.
Check invoice number, issue date, billing entity, customer account, currency, payment beneficiary, tax treatment reference and duplicate status. Match master and house transport numbers, container, tracking or booking numbers. Verify new bank instructions through a known independent contact. A genuine shipment does not prove that the beneficiary, invoice issuer or repeated invoice is correct.
Write the contracted origin and destination points, mode, routing, service level, equipment, package count, gross weight, dimensions, volume and chargeable basis beside the actual movement. Separate port-to-port, door-to-port and door-to-door scope. Record whether customs brokerage, insurance, duties, pickup, final delivery or unloading were included, excluded or separately ordered.
Apply the accepted rate to the agreed billing unit, minimum, weight break, container type, zone or distance. Confirm rate validity and relevant shipment date. Keep freight, fuel and minimum charges visible instead of accepting one blended line. If a forwarder changed the chargeable weight or classification, require the calculation and source measurement before approving the difference.
For every storage, demurrage, detention, waiting, redelivery, remote-area, address-correction, inspection, documentation or handling line, record the published or agreed rate and the event that triggered it. Ask who requested the service, when it occurred, how free time was calculated and which timestamp supports the billed duration. A charge description alone is not event evidence.
Identify government, port, terminal, airline, carrier or broker costs passed through by the billing provider and distinguish them from provider service fees. Request third-party support where the agreement requires it, while protecting confidential information. Link rebates, deposit applications, debit notes and credits to the same shipment so the buyer sees the net position rather than approving gross charges twice.
Code the variance as identity, duplicate, rate, weight, route, service, accessorial, tax, currency, evidence or arithmetic. State billed, expected and disputed amounts, owner and response date. Preserve the supplier explanation and buyer authority for a credit, corrected invoice or accepted exception. Record final payment and lock the packet against reuse while retaining a route-and-charge pattern for future quote comparisons.

Fill only the details relevant to your request
Before you send the request
Use the accepted quote or rate, booking, transport document, pickup and delivery evidence, cargo data, invoice, accessorial support and linked credits. The exact packet depends on the mode and agreement.
They are charges beyond the base movement, such as storage, waiting, redelivery or special handling. The buyer should verify the agreed rate and the actual event that triggered each charge.
Follow the contract and finance policy. Where partial payment is permitted, document the undisputed amount and keep the specific variance open rather than silently withholding the entire invoice.
Use unique invoice and shipment references, search prior bills and credits, track cumulative billed amounts, and lock the completed shipment packet after authorized payment.
Keep the request specific
Carrier liability, invoice deadlines, accessorial rules, tax, customs valuation and dispute rights depend on the contract, transport document, mode, route and law. GSA material below governs U.S. federal agencies and is used only as a clear control example. Apply qualified freight, customs, finance and legal review to the actual shipment.
