Carrier billing audit — finding overcharges before they stick
Updated 2026-08-03
Logistics and finance leaders search for carrier billing audit when they know transporters overbill — often 2–5% of spend — but lack bandwidth to verify every invoice. Here is what to check, in plain language.
Why carrier invoices are hard to trust by eye
A single freight invoice can stack base rate, fuel, residential, detention, reweigh, and minimum charges. Your contract may allow some of those — and forbid others. Spreadsheet audits break when you have multiple carriers and hundreds of shipments per month.
Typical mid-market profiles: 50–500 shipments/month, 3–15 carriers, $5M–$100M annual freight spend. That volume is exactly where systematic carrier billing audit pays for itself.
Checklist: what a carrier billing audit should flag
Fuel surcharge billed above the contracted index or percentage. Base rate or zone that does not match the lane agreement. Duplicate accessorial lines (e.g. residential charged twice). Detention, reweigh, or dimensional weight charges not in your agreement. Minimum charge applied when a lower contracted rate applies.
Each flag should show billed vs correct vs recoverable. Without that, you cannot file a credible claim.
What to do after you find an error
Document the line, cite the contract clause or rate sheet cell, and open a claim on the carrier portal or with your account rep. Track status until credit or refund posts — that is the only signal that matters.
