How to Choose a Freight Audit Company (and What Most Get Wrong)

Published May 29, 2026 · 8 minute read

Choosing a freight audit company comes down to four questions: pricing model (performance-based vs subscription), scope (parcel only, freight only, or both), contract-clause expertise (do they read the Master Rate Agreement or just the invoice), and reporting (plain-language or vendor PDF). Most shippers focus on the carrier's reputation, not the right diligence. Your first audit with Eller is free.

The 4 questions that actually matter

After being on both sides of the audit-firm evaluation conversation for two decades, the same pattern keeps showing up: shippers spend the most diligence time on the wrong question — vendor reputation — and the least time on the one that decides the recovery number — contract-clause expertise. The four questions below are ordered by how much they actually move the recovery number on your account.

1. Pricing model

Performance-based firms get paid only when they recover money for you, typically 20-30% of the recovery. Subscription firms charge a monthly fee regardless of what they find. Performance-based aligns the firm's incentive with yours; subscription doesn't. If a subscription firm has a quiet quarter, they still get paid. If a performance firm has a quiet quarter, they go look harder. On a $4 million annual freight spend, the difference between a firm motivated to dig and one running checklists is often $40,000-$60,000 a year in missed recovery.

2. Scope

A parcel-only firm will miss less-than-truckload (LTL) gold — reclassification, accessorial overcharges, fuel surcharge math errors. A freight-only firm will miss Guaranteed Service Refund (GSR) claims and parcel address-correction abuse. If you ship a mix, make sure the firm you hire audits the mix. Otherwise you're paying for partial coverage and assuming you have full coverage.

3. Contract-clause expertise

Some firms read the invoice. Some firms read the MRA. The difference is often 2-3x recovery on the same account. An invoice-level audit catches duplicate billing, wrong fuel index, missing discount applied. A clause-level audit catches the carrier billing you under a class that your contract explicitly excludes, an accessorial that your MRA caps at a different rate than what was charged, or a minimum-charge floor that doesn't apply to lanes you've negotiated separately. Same invoices, very different reads.

4. Reporting

A plain-language recovery summary tells your CFO what was wrong, what was recovered, and how to prevent it. A vendor-flavored PDF with 18 acronyms and zero context tells your CFO that the audit firm is busy. If you can't explain the report to your CFO in under three minutes, the audit firm hasn't done its job. The whole point is visibility into spend, not a thicker report.

Pricing models compared

Four pricing models cover almost every freight audit company in the market. Here's how they stack up on incentive alignment, total cost, and who they fit:

One concrete number: in-house audit teams typically miss 30-50% of recoverable money compared to a focused outside firm, because invoice processing crowds out clause-level analysis. The numbers come back fast, but the recoveries don't.

What scope looks like — firm types compared

Not every freight audit company audits every mode. Four broad categories cover the market. Knowing which one you're talking to saves a lot of misaligned pitches:

Worked example: $75M annual program, $920K/yr delta between cheapest and deepest finder

A national manufacturer with a $75M annual freight + parcel program (LTL/TL/parcel/intl) quotes three audit firms for the same account.

Gap between Firm A and Firm C: $956K of net recovery per year. Over a 3-year contract: $2.87M. The decision isn't software vs. service or subscription vs. performance — it's whether the audit firm reads the MRA at clause level or just the invoice.

Industry benchmark: Trax claims 5–7% on managed enterprise spend; AFS Logistics cites up to 8% on freight audit programs. For shippers without an active audit program, recovery is almost always at the high end of those ranges in year one.

Subscription vs performance — when each makes sense

Subscription isn't categorically worse than performance. It fits a specific profile. Performance fits a different one. Match the model to your situation, not to whichever firm's salesperson got to you first:

Red flags when evaluating a freight audit company

Most firms look fine on a sales call. The signals that separate the strong ones from the average ones show up in the contract and the questions they can or can't answer. Five red flags to watch for:

1. Lock-in contracts longer than 12 months for performance work. A performance-based firm doesn't need a long lock-in. If they want one, the lock-in is doing work the recoveries aren't.
2. No transparency on what categories they audit. "We audit everything" is a non-answer. Ask for a category list: fuel surcharge math, classification, accessorials, weight discrepancies, address corrections, GSR claims, etc.
3. Refusal to share sample reports. Every legitimate firm has anonymized samples. If they won't share one, they're either new or they don't want you to see the format.
4. No examples of contract-clause-level disputes. If every example they cite is a mechanical billing error (duplicate invoice, wrong rate applied), they're an invoice-level audit firm dressed up as a contract-level one.
5. Aggressive sales push without diligence on your contracts. A firm that wants a signature before reviewing your MRA isn't going to do contract work after the signature either.

What we can't tell from a firm's pitch alone

Every freight audit company has a polished sales deck. Every one of them will cite a top-quartile client, show a recovery percentage that sounds impressive, and walk you through a process diagram. None of that tells you whether they'll find the money on your account. The real signal is their first audit report on your actual invoices and contracts. Most reputable firms will run a free first audit — Eller does, it's our model — precisely because they know the report is the pitch.

Use the first-audit report as the evaluation, not the sales call. Look at whether the findings cite specific MRA clauses by section number, whether the recovery categories match the categories on your shipping profile, and whether the language is plain enough that you could forward it to finance without translation. If the report passes those three checks, the firm is worth a longer engagement. If it doesn't, the slick sales deck was the whole product.

How Eller Audit handles this

We run the first audit free. After that, we're performance-based — typically 22% of recovered dollars, with no platform fee and no long-term lock-in. We audit both freight (LTL and TL) and parcel in the same engagement, so you don't end up with two firms reading two halves of your shipping spend. Contract-clause review against your MRA is included in every audit, not sold separately. Reports are plain-language and built so a CFO can read them in five minutes and a transportation manager can use them as a remediation checklist. That's the whole model.
