Freight Invoice Billing Error Glossary

Freight invoice errors typically run 5–10% of all LTL invoices industry-wide, and they structurally lean in the carrier's favor. Below are the most common categories of billing errors shippers encounter, what causes each one, and what to look for.

Which Error, Which Carrier

Error Type Most Likely Carrier Size Why
Freight Reclassification & Reweighing Large, national Automated dimensionalizer scanners and certified scales systematically re-measure shipments.
Dimensional Weight Upcharges Large, national High-volume carriers scan nearly every shipment, making overcharges more consistent.
Fuel Surcharge Miscalculation Large, national Multi-tier schedules against regional DOE prices increase chances for errors.
Phantom Accessorial Charges Large, national Default accessorial codes applied at terminal level without site-specific verification.
Rate Misapplication Small to mid-size, regional Billing systems may not be tightly integrated with specific negotiated contracts.
Duplicate Billing Small to mid-size, regional Less mature invoicing systems and manual re-entry make duplicates more common.
Detention Past Free Time Small to mid-size, regional Manual dock logs leave room for detention charges that don't match reality.

Duplicate Billing

The same shipment gets invoiced more than once. We match invoices against unique shipment identifiers (BOL, PRO number, or weight/lane combo) to catch reissued invoices that never voided the original.

Rate Misapplication

The invoice charges a rate that doesn't match your negotiated contract—either a missing volume discount or the wrong tariff tier. We compare every charge against your actual rate sheet.

Phantom Accessorials

Fees for services never performed (liftgate on a dock delivery, residential surcharge on a business). These are easy to apply by default but hard to contest without records.

Fuel Surcharge

When the percentage doesn't match your contracted schedule—often caused by using the wrong regional index or an outdated tier calculation.

Reclassification

Carriers re-measure or re-weigh shipments using automated scanners. We help you verify if the physical shipment actually supports the higher class or weight they billed.

Dimensional Weight

Billing based on space occupied rather than scale weight. Common on light, bulky freight where dimensional rules can turn a simple shipment into a much more expensive one.
