How to compare freight audit companies without getting fooled by the biggest “savings” number.

Disclosure: RETALLY is a freight audit and recovery provider

This is not an independent ranking of vendors. It is a buyer framework from a company that sells freight audit and recovery services. The useful question is not who wins an invented top-ten list. It is which operating model, evidence standard, data requirement, and commercial structure fit your freight environment.

Start by identifying which kind of freight-audit company you need

“Freight audit company” covers several different operating models. Comparing them as if they were interchangeable produces a bad shortlist before the first demo begins.

• Freight audit and payment provider. Audits invoices and also participates in carrier payment, allocation, reconciliation, or settlement workflow.
• Audit-only or post-payment recovery firm. Reviews historical charges for supportable overpayments and may pursue recovery after customer authorization.
• Freight-audit software platform. Provides invoice matching, rating, exception management, reporting, and integrations for the buyer's own team to operate.
• Parcel-specialist auditor. Focuses on parcel billing, service failures, dimensional weight, surcharges, and carrier credits rather than the full multimodal freight stack.
• TMS- or 3PL-embedded audit. Audit capability is included inside a broader transportation-management or managed-logistics relationship.
• Independent Second-Look auditor. Tests a population that has already passed through a TMS, internal review, payment provider, or incumbent auditor and measures only supportable residual value.

No model is automatically superior. The first decision is whether you need payment operations, software, historical recovery, or an independent challenge to controls you already have.

12 criteria for comparing freight audit companies

1. Mode and carrier coverage. Confirm whether the provider supports the parcel, LTL, truckload, intermodal, ocean, air, and other modes that actually matter to your network. Ask how new carriers and formats are onboarded.
2. Audit depth. Ask what is actually re-performed: contract rate, fuel, minimums, discounts, accessorial entitlement, dimensional weight, class, reweigh, reclassification, service level, duplicate logic, corrected invoices, and credits.
3. Commercial-authority handling. A provider should be able to explain which contract, tariff, rate confirmation, quote, amendment, schedule, or rule governed the charge and which effective date applied.
4. Shipment-evidence handling. Invoice math alone cannot prove every exception. Ask how the provider uses BOLs, PRO/tracking references, delivery events, weight/class evidence, appointment/dwell records, and other shipment facts.
5. Ambiguity and human review. Find out what happens when records conflict. A good workflow needs an unresolved or review state; forcing every anomaly into valid or invalid creates false positives.
6. Dispute and recovery execution. Does the provider merely flag exceptions, or does it prepare disputes, communicate with carriers, track aging, reconcile credits, and account for reversals? Who is authorized to act?
7. Payment responsibilities. If the company also pays carriers, understand cash handling, approval controls, funding, reconciliation, currencies, GL allocation, segregation of duties, and what data is exported back to your systems.
8. Integration and data portability. Verify the ERP, TMS, WMS, accounting, carrier, EDI/API, flat-file, and reporting interfaces you actually need. Ask what data you can export if you leave.
9. Recovery attribution. Ask how the provider treats automatic credits, customer-known issues, existing disputes, incumbent findings, duplicate opportunities, and credits already in flight. A second auditor should not claim someone else's result.
10. Pricing basis. Compare per-invoice charges, subscription fees, implementation costs, fixed-fee audits, contingency percentages, and any percentage calculated from estimated “savings.” Confirm whether the fee is based on flagged value, approved claims, or money actually recovered.
11. Security and retention. Ask where customer data moves, who can access it, what providers or subprocessors are involved, how long records are retained, how deletion works, and which security claims are independently evidenced.
12. Proof quality. Request a worked example, sample exception, sample dispute package, recovery-status output, or reference relevant to your freight mix. Marketing totals are less informative than a result you can trace from invoice to settlement.

Ask every provider to show one finding from beginning to end

A useful sample output should let finance or transportation answer these questions without relying on a black-box score:

• Which invoice and shipment are being reviewed?
• What amount was billed and what amount should have been billed?
• Which commercial source controls the expected amount, and was it effective on the shipment date?
• Which shipment facts support the calculation?
• What remains unresolved and who reviewed the finding?
• Was recovery action authorized?
• What did the carrier or vendor do?
• Did an eligible credit, refund, remittance, or other realized benefit actually post?
• Was any amount later reversed?

RETALLY publishes a buyer-visible Evidence Standard and recovery-status example so those states are inspectable.

Compare freight-audit pricing using the same denominator

Two prices cannot be compared until you know what each provider counts as the billable unit. Common models include per-invoice processing, monthly or annual subscription, implementation plus usage, fixed-fee forensic work, and contingency pricing.

For contingency work, ask exactly what triggers the fee. A percentage of an estimated opportunity is economically different from a percentage of an approved claim, and both differ from a percentage of eligible funds actually received or posted. Ask how reversals, automatic credits, partial settlements, offsets, taxes, and pre-existing claims affect the calculation.

Already have a freight audit company? Compare providers differently

A mature shipper may already use freight-audit software, an audit-and-payment provider, a TMS, a 3PL, or an internal AP review process. In that situation, replacing the incumbent may be the wrong first question.

An independent Second-Look Recovery Audit can instead freeze the historical population and the incumbent-known findings, automatic credits, active disputes, and other known matters, then test whether any supportable residual remains.

The key commercial question is attribution: if an existing process already found or initiated an adjustment, a challenger should not relabel it as new savings.

Red flags when evaluating a freight-audit provider

• “Savings” is presented without distinguishing estimates, validated findings, approved claims, and realized recovery.
• The provider cannot show the source rate or evidence behind a material exception.
• Missing rate authority silently becomes a zero or assumed expected charge.
• Corrected invoices and credit-rebill sequences are treated as simple duplicates without economic-identity review.
• Automatic credits or an incumbent's existing findings are counted as new recovery.
• The sales team promises a recovery rate without defining population, mode, evidence quality, or denominator.
• The data-retention or deletion answer is vague despite the provider requesting contracts, invoices, or payment information.
• The provider claims security certifications that do not clearly apply to the customer-data environment.
• Carrier contact or dispute authority is assumed rather than explicitly granted.
• The contract tail or finding-origin clause is unclear.

A practical shortlist process

1. Define the job. Decide whether you need pre-pay control, payment, post-payment recovery, software, or a second look.
2. Map your freight. List modes, carriers, countries, currencies, invoice volume, annual freight spend, locations, and current systems.
3. Use one scorecard. Compare every provider on the same 12 criteria instead of letting each demo define its own success metric.
4. Request a representative sample. Use a bounded data set or controlled example that resembles your actual freight mix.
5. Trace one result completely. Follow one exception from invoice identity through authority, calculation, dispute, settlement, and reversal treatment.
6. Read the commercial definition. Confirm exactly what is billable, what is excluded, and when a fee is earned.
7. Check the exit. Understand data export, deletion, contract term, termination, and any post-termination tail.

For freight-heavy distributors and multi-site shippers, involve both finance/AP and transportation/logistics. Finance owns the economic outcome; operations often owns the shipment context needed to explain it.
