How do you read an LTL freight invoice?
Last reviewed 2026-07-02
An LTL invoice builds from a base rate set by freight class and weight, then applies your negotiated discount, a fuel surcharge, and any accessorials, netting to the amount billed. To read it for errors, verify the class and weight, confirm the discount matches your contract, and check each accessorial against the shipment.
- The base rate comes from freight class (NMFC) and billed weight.
- Your negotiated discount applies to that base rate.
- Fuel surcharge and accessorials are added on top.
- Wrong class, wrong weight, or a missing discount are the common errors.
The parts of the invoice
Freight class and NMFC code, billed weight, the base or tariff rate, your negotiated discount off that rate, the fuel surcharge, accessorials, and the net amount. Each line moves the total, and each is a place an error can enter.
Reading it for errors
Confirm the freight class and NMFC match what shipped, check the billed weight against the actual weight and dimensions, verify your negotiated discount was applied, recompute the fuel surcharge against the index, and match each accessorial to the shipment.
Where LTL invoices go wrong
Reclassification to a higher class than the goods warrant, a reweigh that inflates billed weight, a discount that was never applied, and accessorials with no supporting event. Any of these raises the invoice above your contracted cost.
Common questions
What is freight class?
An NMFC classification based on density, handling, stowability, and liability that sets the base rate. Being billed at a higher class than the goods warrant is a common overcharge.
Why does billed weight differ from my weight?
Carriers reweigh and remeasure shipments. A reweigh that does not match the actual weight and dimensions inflates the bill and is disputable.
How do I know my discount was applied?
Recompute the base rate and apply your contracted discount. If the billed rate is higher, the discount was missed, which a line-by-line audit catches.
