5 Freight Billing Errors Most Importers Never Catch

Here's an uncomfortable truth: a meaningful slice of freight invoices contain errors, and almost all of them favor the carrier. If nobody on your side is auditing line by line, you're paying them.

1. Duplicate invoices

The same shipment billed twice under slightly different reference numbers. It happens more than you'd think, especially when a load gets re-tendered or re-rated. If your AP team pays by invoice number, duplicates sail right through.

2. Incorrect fuel surcharges

Fuel surcharges are tied to a published index, but the rate that actually shows up on your invoice doesn't always match. A few points off on every shipment adds up to real money over a year.

3. Unauthorized accessorials

Detention, layover, liftgate, residential — accessorial charges are where invoices get padded. Some are legit. Some were never agreed to. You only catch the difference by comparing the invoice to what was actually contracted.

4. Rate discrepancies vs. your contract

You negotiated a rate. The invoice shows a different one. This is the single most common — and most recoverable — error we find. It usually means the carrier billed off an old or default tariff instead of your agreement.

5. Weight and dimensional errors

Reweighs and re-measures can bump a shipment into a higher class or a bigger dim-weight bracket. Sometimes that's correct. Sometimes it's a thumb on the scale. Either way, you should be checking.

The fix isn't complicated — it's just tedious

Auditing freight bills is boring, detailed work. That's exactly why it pays. You compare every invoice against the contract and the actual shipment, flag what doesn't match, and dispute it. Most companies don't have the time. That's the whole reason the errors persist.
