Amazon Shortage Claim Recovery Service Pricing: Contingency vs Flat Fee

That means that there's no “fair” percentage for an Amazon shortage claim recovery service. Performance fees are inherent in the business of dealing with lost or damaged goods, where you lose what is unknown until your client needs and shares it with you. The actual cost depends on what the fee covers, what work it includes, which recoveries it excludes, and when the provider earns the fee.

A lower commission does not always mean a lower cost. It may still cost more if the provider charges on automatic credits, existing claims, or a wider definition of recovered funds.

What are you actually paying a shortage-claim recovery service to do?

For a U.S. Vendor Central team, a shortage claim is a 1P quantity-reconciliation deduction. It is often called Purchase Quantity Variance, or PQV.

It is different from a Seller Central or FBA reimbursement. It should also not be grouped with every other type of Vendor Central deduction. If you first need to understand the process, SalesDuo’s guide explains how Amazon Vendor Central shortage claims work.

The service fee often covers more than simply filing a dispute. Depending on the statement of work, or SOW, the provider may:

• Review older deductions
• Check supporting evidence
• File disputes
• Re-dispute or escalate unresolved cases
• Match recovered credits with the right claims
• Provide status reports
• Help find repeated operational problems

The contract determines what is included, not the service name.

This matters because two providers may charge the same percentage but offer very different levels of support.

For one provider, claim discovery and credit reconciliation may be part of the service. However, an alternate provider may only receive disputes. In that situation, your finance and operations teams may still need evidence, deal with reversals, and perform the accounting.

The four pricing models you are likely to see

Most proposals use one of four pricing models: contingency, fixed or subscription, hybrid, or project and retainer pricing.

The model name is only the first thing to check. You also need to understand when the provider gets paid, what the fee applies to, and what work is included.

Contingency or success fee

With a contingency model, the provider charges a percentage of qualifying recovered funds.

The provider takes on more performance risk because they earn money only when recovery happens under the contract. The buyer also avoids a high upfront fixed cost.

This model can make sense when you don't know how large the recoverable backlog is or when the account hasn't been reviewed recently.

The biggest contract risk is the fee base.

For example, a 15% fee on new cash recovered because of the provider’s work is very different from a 15% fee on every credit that appears during the contract.

The SOW should clearly explain whether the provider can charge fees on:

• Claims that were already open
• Amazon auto-corrections
• Credits already being processed
• Credits that are later reversed

Fixed monthly or annual fee/subscription

A fixed model charges the same monthly or annual amount, regardless of how much money is recovered during that period.

This gives the buyer more predictable costs, but the buyer also takes on more risk if recovery volume drops.

This pricing model works well for accounts with a steady flow of claims and teams that use the service regularly.

The main risk is paying for a service you don't fully use. Another risk is assuming a software subscription includes the same amount of work as a managed service.

Ask exactly who will:

• Prepare evidence
• Submit claims
• Follow up on claims
• Match credits with disputes
• Help when a dispute gets stuck

Hybrid base fee plus performance fee

A hybrid model combines a fixed base fee with a smaller performance-based fee.

This gives the provider some predictable income while still connecting part of the fee to recovery results.

It may work well when a company needs ongoing monitoring but also wants part of the provider’s payment linked to performance.

The main risk is paying twice for the same work.

Make sure the fixed fee and success fee cover different services. Also check whether the percentage is calculated before or after setup fees, platform costs, or other fixed charges.

Project, retainer, or custom scope

A project or retainer model charges for a specific project, time period, audit, cleanup task, or wider finance and operations project.

This can be useful when you want help with a limited piece of work instead of an ongoing recovery service.

The main risk is scope creep.

The contract should clearly explain:

• Which claim periods are included
• Whether the provider will continue follow-ups and re-disputes after the project ends
• What happens to claims that are still unresolved at the end of the contract

The public pricing examples below were reviewed on November 4, 2026. They illustrate different provider pricing structures, not an industry benchmark or guaranteed U.S. rates. Scope, marketplace eligibility, fees, and contract terms may change. Confirm the current offer directly with each provider.

What a “fair rate” really means: inspect the fee base before the percentage

A fair rate is not simply the lowest percentage.

A fair quote lets you clearly understand the real cost and compare it with other options.

You need to know:

• What amount the fee is calculated on
• When the fee becomes payable
• Which claim types are included
• Which claims or credits are excluded
• How much work your own team still needs to do

Start by checking what the provider means by “recovered.”

A provider may count recovery when:

• Amazon approves the case
• A credit appears on the account
• An invoice is offset
• Cash reaches the business

These events do not always happen at the same time.

A credit may also be reversed later. The SOW should clearly explain which event triggers the fee and what happens if the recovery is later taken back.

Then check what the fee base includes. Ask whether the provider charges for:

• Amazon auto-corrections that would have happened without the provider
• Claims or disputes that were already open before the contract started
• Credits already approved or being processed
• Price claims, chargebacks, co-op deductions, returns, or other claims outside shortage/PQV
• Older claims found during an audit but not actually worked by the provider

You should also compare the provider’s fee with the cost of the work your own team still needs to do.

A cheap software subscription may require your team to spend a lot of time preparing evidence and matching credits.

A more expensive managed service may include more of that work.

Qualifying recovered cash is the amount the contract treats as eligible for a provider fee. Incremental cash recovery is the additional recovery reasonably attributable to the provider's work. These amounts may differ when a contract includes automatic corrections, already-open disputes, or credits that were being processed before the engagement.

Use qualifying recovery to calculate contractual charges. Use incremental recovery to evaluate the additional financial value of hiring the provider.

To compare quotes properly, calculate the total provider fees divided by the extra cash recovery that can reasonably be linked to the provider. Then add the internal work and admin cost your team still carries.

Decision rule: Do not choose a provider only because it has the lowest percentage. Compare the expected net value after looking at the scope, exclusions, internal work, and contract risks.

Run the math: contingency vs flat fee

A simple break-even calculation can help you compare contingency pricing with fixed pricing.

Use the contract’s definition of qualifying recovered cash. Do not use the total amount of deductions found in an audit unless the contract actually charges fees on that amount.

Contingency fee = qualifying recovered cash × contracted fee percentage

Net recovery after provider cost = qualifying recovered cash − provider fees − fixed/setup fees − internal/admin cost

Flat-fee break-even recovery = annual fixed fee ÷ contingency rate

When performing these calculations, make sure to count each cost only once. If the total provider fee already includes setup, subscription, or fixed charges, you shouldn't subtract those amounts again. The examples that follow compare contractual fees using qualifying recovery; however, a separate incremental-value assessment should not include recovery that is not reasonably tied to the provider.

Imagine this hypothetical situation. Let's say both services deal with similar kinds of claims and recovery tasks, use the same criteria to determine what qualifies as a recovery, and don't have any extra setup charges. Internal workload and credit reversals aren't part of the initial calculation and should be assessed on their own.

The contingency fee would be:

$60,000 × 20% = $12,000

That leaves $48,000 before internal or admin costs.

Now compare that with a fixed service that costs $2,000 per month.

That equals:

$2,000 × 12 = $24,000 per year

At a 20% comparison rate, the fixed model breaks even when annual qualifying recovery reaches $120,000:

$24,000 ÷ 20% = $120,000

Below $120,000, the fixed fee has a higher effective percentage.

Above $120,000, the fixed fee has a lower effective percentage, as long as the service scope and internal workload are similar.

The example assumes that qualifying recovered funds remain valid. If Amazon later reverses a credit, the final cost depends on whether the contract also reverses or refunds the associated provider fee.

These numbers are only examples to explain the calculation. They are not SalesDuo pricing, a market standard, or an expected recovery rate.

When contingency pricing tends to fit

Contingency pricing can make sense when you are not sure how much money you can recover or how successful the claims will be.

It can also work for buyers who want a low upfront cost.

The provider takes on more result-based risk because they earn more only when recovery happens according to the contract.

The downside appears when recovery becomes very high.

A percentage that looks small on a limited backlog can become a large fee as recovery volume grows.

That is why the fee base and exclusions become even more important at higher volumes.

A contingency proposal is easier to compare when the SOW clearly explains:

• What counts as new or incremental recovery
• Whether credits that were already going to happen are excluded
• What happens if Amazon later reverses or claws back a credit

When flat-fee or subscription pricing tends to fit

Flat-fee or subscription pricing can make sense when recovery volume is steady, and the company wants predictable costs.

It may also work well when your internal data and evidence process is already organized enough to use the service regularly.

As qualifying recovery increases, the effective percentage of a fixed fee can become lower.

However, you still pay the fixed fee during months with lower recovery.

A fixed service is only truly cheaper if it provides a similar level of service and your own team can support the process.

A software subscription that finds claims and automates filings is not automatically the same as a managed service that also handles evidence checks, follow-ups, reconciliation, and reporting.

For either model, identify who collects evidence, validates claim eligibility, submits disputes, handles rejections, follows up with Amazon, reconciles credits, and prepares reports. Work that remains with your internal team should be included in the cost comparison.

If repeated shortages stem from data, purchase order, shipment, ASN, or invoice issues, treat recovery and prevention separately. SalesDuo’s Amazon EDI for Vendor Central guide covers the operational side without treating prevention work as part of the same recovery fee.

How to compare shortage-recovery quotes apples to apples

Put every provider proposal into the same format before comparing the price.

The goal is not to find the smallest percentage. The goal is to understand which option gives you the best expected result with manageable work for your team.

Effective provider fee rate = Total external provider fees ÷ Incremental cash recovery attributable to the provider × 100.

Incremental recovery after costs = Incremental cash recovery attributable to the provider − Total external provider fees − Additional internal and administrative costs.

If incremental recovery cannot be estimated reliably, disclose that uncertainty rather than presenting a verified effective fee rate. The rate cannot be calculated meaningfully when incremental recovery is zero.

After filling out this table, calculate the effective fee rate under low, medium, and high recovery scenarios.

Then compare how much cash remains after provider fees and the estimated cost of your team’s internal work.

This gives finance and procurement teams a fairer way to compare providers that use different pricing models.

If you are still choosing between provider types, use SalesDuo’s guide to compare shortage claim recovery providers after you have compared the pricing and contract terms.

Where SalesDuo fits

Frequently Asked Questions about Amazon Shortage Claim Recovery Service

What is a fair fee for an Amazon shortage claim recovery service?

There is no single fair percentage.

Compare the fee base, the work included, exclusions, the billing event, your internal workload, and the amount you keep after paying provider costs.

Public examples of 15%, 20%, and 25% show that pricing varies. They do not prove that one percentage is the market standard.

How do contingency shortage-recovery fees work?

A contingency fee is a percentage of the successful recovery defined in the contract.

The agreement should clearly say what counts as recovered and when the provider earns the fee.

For example, case approval, account credit, invoice offset, and cash receipt are different events. The contract should clearly choose one event that can be checked and verified.

Do I pay a recovery service when a claim is denied?

It depends on the pricing model and the SOW.

A pure success-fee model may only charge when qualifying recovery happens.

A fixed fee, subscription, or retainer may still be payable even if some claims are denied.

Always check the payment trigger in the contract instead of guessing based on the pricing model’s name.

Can a provider charge a fee on Amazon auto-corrections or claims already in progress?

Yes, if the contract allows it.

Ask the provider to clearly state whether the fee applies to auto-corrections, older disputes, open claims, approved credits, and payments that were already being processed before the engagement started.

When is a flat fee cheaper than a contingency fee?

Use this break-even formula:

Annual flat fee ÷ contingency percentage

For example, a $24,000 yearly fixed fee compared with a 20% contingency fee reaches break-even at $120,000 in qualifying annual recovery.

After that, also compare the work included and your internal costs before deciding which option is actually cheaper.

What should “recovered” mean in a shortage-recovery contract?

“Recovered” should be connected to a clear event that both sides can verify.

For example, the contract may define it as a qualifying credit or cash recovery tied to the provider’s work.

The agreement should also explain how it handles reversed credits, older claims, auto-corrections, and other exclusions.

Are Vendor Central shortage recovery services the same as FBA reimbursement services?

No.

Vendor Central shortage or PQV deductions are part of a 1P vendor relationship.

Seller Central and FBA reimbursements follow a separate 3P process with different rules and workflows.

For that topic, use the FBA reimbursement claims guide.

What should I ask for before signing a shortage-recovery SOW?

Ask for clear details about the service scope, fee base, exclusions, payment trigger, older or open claims, auto-corrections, reversals, setup or minimum fees, evidence ownership, data permissions, reporting and exports, contract length, termination notice, and offboarding.

You should be able to connect every fee to a clearly defined recovery event.
