The short answer
An LTL invoice moves when the carrier reweighs, remeasures or reclassifies the shipment and rebills the difference. Ask for the inspection evidence before you accept or dispute it.
Do these first
Identify the exact line or rating input that changed before disputing the total.
- Compare quote and invoice — look for weight, class, dimensions and accessorial changes.
- Ask for inspection support — request reweigh or dimension records when those changed.
- Compare the BOL — confirm what was actually tendered.

What to ask for
Useful supporting information can include:
- Certified reweigh record
- Dimensioner results
- Revised class or NMFC basis
- Tariff item applied
- Accessorial detail
- Original and corrected handling-unit count
Estes states that invoices may be changed for certified-scale reweighs, dimensioner scanning results or NMFC standards and directs customers to submit supporting documentation for rating disputes.
