There is no single freight audit contingency fee percentage, and anyone who quotes you one without asking what it applies to is selling, not informing. The two sources we could fetch and verify put the provider’s share somewhere between 25 and 50 percent of recoveries. A much lower range, roughly 6 to 12 percent, circulates widely in search results and we could not trace it to a source we could stand behind. Both are probably describing real contracts, because they are measuring different things.
So the percentage is the least interesting number in the agreement. What decides your cost is the basis it is applied to, the definition of a qualifying recovery, the minimum, and the tail. This post walks all four, with the published ranges laid out and attributed, and shows what a contingency relationship costs over three years rather than one invoice.
We sell flat-price software, and we also sell a contingency option. Read this as a buyer’s guide from someone with a stake in the answer, and check the arithmetic yourself.
What the published sources actually say
Almost nobody in freight audit publishes pricing. Cass’s freight audit and payment page discloses no pricing, no fee structure, and no pricing model. A buyer’s guide from ShipperGuide correctly names all three models in the market (per-invoice fixed fee, percentage of spend or savings, tiered subscription) and then gives no figures for any of them.
Two sources do give numbers. Here is exactly what each one says and who wrote it.
| Source | Figure published | Who wrote it | How to read it |
|---|---|---|---|
| Senvo | Third-party freight audit firms commonly take 30 to 50 percent contingency on recoveries; worked example of a 40 percent contingency costing 72,000 euros for a 3 million euro shipper | A vendor, in a post positioned against contingency pricing | Directionally useful, but the author benefits if contingency looks expensive |
| Darrigo Consulting | Contingency is the norm; net savings to the shipper after provider fees are typically 50 to 75 percent of total recovery | A consultant | Implies a provider share of 25 to 50 percent, which corroborates Senvo from a different direction |
| Search snippets and comparison content | Roughly 6 to 12 percent of audit savings | Untraceable to a fetchable source | We are naming it because it exists and you will see it. We are not citing it, because we could not verify it |
We are not going to resolve that conflict with a single number, and you should be suspicious of anyone who does, including us. What we can do is show why both ranges are plausible.
The Senvo example implies a recovery rate worth checking
Senvo’s worked example is 72,000 euros of fee on a 3 million euro shipper at 40 percent contingency. Work it backwards. A 72,000 euro fee at 40 percent implies 180,000 euros of recoveries, which is 6 percent of that shipper’s spend.
Six percent is a high recovery rate. Darrigo Consulting publishes recovery benchmarks of 1 to 3 percent of spend for truckload, 3 to 8 percent for LTL, and 2 to 5 percent for parcel. So Senvo’s example sits at the top of the LTL band and well above anything a truckload shipper should expect.
Run that check on every number a vendor shows you: divide it out and ask what recovery rate it assumes about your freight. If a proposal’s savings projection implies 6 percent recovery on a truckload-heavy book, the projection is doing the selling.
Why a 10 percent quote and a 40 percent quote can both be honest
Four variables move the percentage, and none of them are usually stated in the same sentence as the percentage.
Basis. A percentage of recoveries is a cut of cash that actually comes back. A percentage of savings can include negotiated rate improvements, avoided charges, and credits you never had to chase. A percentage of spend under management does not depend on findings at all. The same vendor can quote 8 percent of spend-based savings and 40 percent of hard recoveries and mean two entirely different products. Ask which one, in writing, before you compare quotes.
Scope. Audit-only (find the errors, hand you the file) prices differently from audit and payment (find the errors, hold the funds, pay the carriers, produce the accruals, code the GL). A bundled service has other revenue lines, including float on money in transit, and can afford a smaller contingency percentage.
What counts as a finding. Some contracts apply the percentage to every credit that lands during the term, including exceptions your own AP clerk flagged and disputes you filed before the vendor arrived. Others apply it only to net-new findings the vendor sourced. That single definition can double or halve your effective rate without changing the percentage on the cover page.
Volume and mix. A 200-load shipper and a 20,000-load shipper are not on the same rate card. Neither card is published.
The percentage is not the price. The basis is.
Here is the arithmetic, with every input labeled as an assumption so you can swap your own in. These are illustrative figures, not findings.
- Assumption: 500 loads a month at an all-in average of $1,800 per load. Annual freight spend of $10.8 million.
- Assumption: recoveries of 1 percent of spend, the low end of Darrigo’s truckload benchmark. That is $108,000 a year.
- Assumption: total “savings” as a broader definition, including rate improvements and avoided charges, of 3 percent of spend, or $324,000 a year.
| Quoted percentage | Basis it applies to | Annual fee | Effective rate on hard recoveries |
|---|---|---|---|
| 40% | Recoveries only ($108,000) | $43,200 | 40% |
| 25% | Recoveries only ($108,000) | $27,000 | 25% |
| 12% | Total savings ($324,000) | $38,880 | 36% |
| 8% | Total savings ($324,000) | $25,920 | 24% |
| 1% | Spend under management ($10.8M) | $108,000 | 100% |
Look at the 12 percent row against the 40 percent row. They are within $4,320 of each other. That is how a genuinely lower-sounding percentage produces a nearly identical invoice, and it is the most likely explanation for the 6 to 12 percent range circulating alongside the 30 to 50 percent one.
The bottom row is the one to watch. A percentage of spend is not a contingency arrangement at all, whatever the deck calls it. It is a fixed fee wearing a percentage costume, and it is the only structure in the table where you pay the same whether the vendor finds anything or not.
The lifetime cost of an error nobody fixes
Contingency pays for recovery. It does not pay for prevention, and that is where the three-year number diverges from the one-year number.
Say, illustratively, that of that $108,000 recovery pool, $40,000 a year is one recurring pattern: a single carrier computing fuel surcharge off the wrong week of the DOE index on every load in a lane. That is a mechanical error, and it is fixable at the source in one conversation, as long as you can show the carrier the recomputation. The method is in how to calculate a truckload fuel surcharge from the DOE index and which DOE week applies to a load.
Two paths.
- Fix it. You spend an afternoon, the carrier corrects its rating table, and the $40,000 stops leaving. Year two costs you nothing and year three costs you nothing.
- Recover it. Under a 30 percent contingency, you net $28,000 a year and pay $12,000 a year, every year, for as long as the error persists. Over three years that is $36,000 in fees on a problem that had a one-afternoon fix.
Nobody in this arrangement is acting in bad faith. The incentive is simply pointing the wrong way: a vendor paid on recoveries has no financial reason to end the error, because the error is the revenue line. Most contingency providers will still tell you about the pattern if you ask. They just will not be paid to make it stop.
The practical response is to make root-cause reporting a contractual deliverable rather than to swear off contingency: a quarterly summary by carrier, by charge code, and by error type, with the recurring patterns named. If a provider will not put that in the agreement, you have learned what you are buying.
The contract terms that decide your real rate
The percentage goes on page one. These live on page six, and they matter more.
Definition of a qualifying recovery. The single most expensive clause in the document. Does it cover credits your team identified independently? Disputes already in flight when the term started? Carrier-initiated corrections that would have happened anyway? Ask for an explicit carve-out for exceptions you flag first, and for a mechanism to claim it, because a carve-out with no process is not a carve-out.
Monthly or annual minimum. Many contingency contracts carry one. A minimum turns “no recovery, no fee” into a fixed cost in quiet months, which is exactly the property you were paying a percentage to avoid. If there is a minimum, price the deal as a subscription with a variable component and compare it that way.
The tail on recoveries in flight. Disputes filed during the term but paid after it ends. Contingency contracts routinely claim a percentage on these, sometimes for 12 or 24 months past termination. That is not unreasonable in principle, since the vendor did the work. It becomes unreasonable when the tail is open-ended or when it attaches to recoveries the vendor never touched.
Term and auto-renewal notice. A 36-month term with a 90-day cancellation window is a different product from the same percentage month to month. Diary the notice date the day you sign.
Exclusivity. Some agreements bar you from auditing the same invoices yourself, or from engaging a second provider, for the term. Read that one carefully if you intend to keep an internal audit function.
Look-back scope on historical claims. If the engagement includes a sweep of already-paid invoices, the recoverable window is bounded by law, not by the vendor’s ambition. The 180-day window to contest a bill under 49 U.S.C. 13710 and the 18-month period to sue for overcharges under 49 U.S.C. 14705 are hard limits, and the full set is laid out in every freight billing deadline that can cost you money. A look-back priced on a 24-month file when most of it is time-barred is priced on air.
Who talks to your carriers. Some providers dispute in your name and in their own voice. That has a relationship cost, and you pay it, not them. Before you hand that job over, be sure the disputes are well founded, because a provider short-paying on a bad reading of a rate confirmation that does not match the carrier invoice spends your goodwill, not theirs.
Data ownership at exit. Your invoices, your extracted line items, your dispute history, your recovery ledger. Get the export format and the deletion commitment in the agreement, not in an email.
Findings versus recoveries in the reporting. A finding is not money. Ask what percentage of flagged exceptions actually get collected, and require the reporting to show both. A provider that only reports findings is reporting on its own effort, not your outcome.
Where contingency is genuinely the right buy
We sell against it, so take this in the spirit it is offered. Contingency has structural advantages a subscription cannot match.
- No fixed line item. Nothing to defend in a budget review. For a controller who cannot get new software approved, this is not a small thing.
- The vendor carries the risk. Clean bills cost you nothing.
- It is the correct shape for a one-time historical sweep. You are buying a project with a defined end, not a process, and you want the vendor’s risk appetite rather than your own.
- Low volume changes the math. Under roughly 200 loads a month, a flat monthly fee is a large share of a small recovery pool. Contingency scales down to zero. Our own pricing does not, and we say so.
- No internal bandwidth. If nobody in your shop will work an exception queue, a percentage of money you would otherwise never have seen is a good trade. A percentage of money your own team already found is not.
For comparison against the other two models at specific volumes, the numbers are worked out in what freight audit really costs across the three pricing models, and the build-versus-buy version of the same question is in in-house versus outsourced freight audit break-even math.
Before you sign: the checklist
- Get the percentage and the basis in the same sentence, in the contract. Recoveries, savings, or spend.
- Get the written definition of a qualifying recovery, plus a carve-out for exceptions you identify first and a process for claiming it.
- Ask whether there is a minimum. Price the deal with the minimum as a fixed cost.
- Read the tail clause. How long, and does it attach to recoveries the vendor did not source?
- Check the term, the auto-renewal, and the notice window. Diary the notice date on signing day.
- Check for exclusivity that would stop you auditing your own bills.
- Require root-cause reporting by carrier and charge code as a deliverable, so recurring errors get fixed rather than farmed.
- Require reporting on recoveries collected, not just exceptions flagged.
- Divide any savings projection by your own spend and ask what recovery rate it assumes. Compare that to the 1 to 3 percent truckload and 3 to 8 percent LTL benchmarks.
- Settle data ownership, export format, and deletion in writing before the first invoice moves.
One more thing, and it applies whichever way you go. You cannot evaluate any percentage until you know your own error rate, because the fee is a percentage of a number you have not measured. Reconcile your last 60 days of invoices against the rate confirmations and the PODs before you take a sales call. Even a rough count of exceptions per hundred loads, broken out by charge type, turns every proposal in front of you from a story into arithmetic. Catching a repeated bill twice is the easiest place to start, and duplicate freight invoice detection is the one exception type you can measure without any tooling at all.
