How a contingency freight audit works (and what to ask before you sign)

By Meet Bhadani, Maritime Freight Review, Moncton, NB. Updated 26 October 2026.

A contingency freight audit means the auditor is paid only if money is recovered. There is no upfront bill for the review itself. This guide explains how that works, where the details matter, and what to ask any auditor before you agree.

How it works

  1. You send carrier invoices and the documents that show what you agreed to pay, such as a rate agreement or quote.
  2. The auditor checks each invoice against those terms and lists the charges that look wrong.
  3. You review the findings. Claims go to the carrier only with your approval.
  4. If the carrier refunds or credits money, the auditor takes an agreed share of the amount recovered.
  5. If nothing is recovered, you owe nothing.
Illustrative example (made-up numbers). The carrier agrees to refund $1,000 before tax. With a 35% share, the fee is $350 and you keep $650. If the carrier recovers nothing, the fee is $0.

Why companies choose it

Where the details matter

Contingency deals are not all alike. Two offers with the same percentage can cost very different amounts, depending on the terms below.

TermWhy it matters
What the percentage is applied toRecovered amount before tax, after tax, or total savings. Before-tax is the cleanest, because tax adjusts on its own.
What counts as a recoveryCash refunds, credits on your next invoice, or both. Make sure a credit you never use does not count.
Ongoing feesSome agreements take a share of future savings for months or years. Ask whether the fee applies only to money actually recovered.
Contract length and exitCan you stop at any time? Is there a minimum term?
Who talks to your carrierYou should approve claims first and know who is contacting your carrier on your behalf.
Your dataIs there a confidentiality agreement before you send anything? What happens to your files afterwards?
Other chargesSetup fees, reporting fees, or minimums turn "no cost" into a cost.

Questions to ask any auditor

Is a contingency audit right for you?

It suits companies that ship regularly, pay carrier invoices without checking each line, and have an agreed rate or quote to check against. It is less useful if you have very few shipments or no agreed rates, because there is little to compare against. An honest auditor will tell you that after looking at a sample.

How Maritime Freight Review does it

I do not promise a result in advance, because it depends on your carriers, your volume and what your invoices show.

Common questions

What does contingency mean in a freight audit?

It means the auditor is paid only from money recovered for you. If nothing is recovered, you pay nothing for the review.

What percentage do contingency freight auditors charge?

It varies by firm and by contract. Always ask what the percentage applies to and get the terms in writing.

Do I pay if no overcharges are found?

Not under a true contingency arrangement, but check for setup fees, reporting fees or minimums.

Do I need to give up my carrier relationship?

No. You approve claims first, and you decide how and whether your carrier is contacted.

Want someone to check your invoices?

Send about 10 recent freight invoices and your rate sheet. The first review is free, and you pay only a share of money actually recovered.
