5 Most Common LTL Freight Billing Errors

1. Residential Delivery Surcharges on Commercial Addresses

This is the single most common overcharge we see. Carriers apply a residential delivery surcharge ($75-$150 per shipment) to addresses that are actually commercial. This happens because carrier address databases are often outdated or incorrectly classify mixed-use buildings.

How to catch it: Cross-reference every residential surcharge against the USPS Residential Delivery Indicator (RDI) database. If the address is classified as commercial, you have a valid dispute.

2. Fuel Surcharge Calculation Errors

Fuel surcharges are calculated based on the DOE (Department of Energy) National Average Diesel Fuel Price index, which updates weekly. Carriers sometimes apply the wrong week's index, use an incorrect bracket from your rate agreement, or calculate the percentage against the wrong base amount.

How to catch it: Know your fuel surcharge table. For each shipment, verify the DOE index for the week it moved, find the correct bracket, and calculate the expected surcharge. Compare against what was invoiced.

3. Incorrect Freight Class

Freight class determines your rate per hundredweight (CWT). If a carrier bumps your shipment to a higher class than what was actually shipped, your base charge increases significantly. This can happen due to inspection reclassification or data entry errors.

How to catch it: Compare the freight class on the invoice against your bill of lading. If they don't match, dispute it with your BOL as supporting evidence.

4. Duplicate Invoices

It's more common than you'd expect: the same shipment billed twice, sometimes on different invoices weeks apart. This can happen due to carrier billing system errors, re-bills after corrections, or shipments that cross billing cycles.

How to catch it: Match every PRO number across all invoices. Also check for shipments with identical origin, destination, date, weight, and amount — even if the PRO numbers differ.

5. Accessorial Charges Not in Your Rate Agreement

Carriers sometimes apply accessorial charges (limited access, notification, detention) that aren't part of your negotiated rate agreement, or charge rates higher than what you agreed to.

How to catch it: Maintain a list of every accessorial in your rate agreement with the contracted rate. Flag any accessorial on an invoice that either isn't in your agreement or exceeds the agreed rate.

The Bottom Line

Industry data shows that 5-8% of LTL freight invoices contain billing errors, almost always in the carrier's favor. For a company spending $500K/year on LTL freight, that's $25K-$40K in overcharges annually.

The challenge is that catching these errors requires comparing every line item against your rate agreement, fuel surcharge tables, and address databases.
