Search for help with missing Amazon reimbursements and you will find four kinds of FBA reimbursement companies: contingency firms that take a cut of what they recover, software tools that find discrepancies but file nothing, full-service agencies that treat reimbursements as one line of a bigger job, and freelancers who do it all manually. Each works. Each fails a different seller.
This guide compares them by pricing model, strengths, and fit, so you can pick by business stage instead of by sales page.
- The four provider types differ in one core way: how much of the claim-to-credit loop they actually finish for you.
- Contingency pricing is common but not automatically cheapest — read the definition of "recovered" and the rejection policy before comparing rates.
- Software finds money; it does not chase it. Someone on your team still owns the case work.
- Agencies bundle reimbursements with operations, which suits sellers who also need PPC, listings, and account health covered.
- Fit depends on volume and internal time, not on which company has the loudest testimonials.

What Do FBA Reimbursement Companies Do?
FBA reimbursement companies find money Amazon owes sellers — lost inventory, missing refund reimbursements, and overcharged fees — and manage the claims that recover it. The full loop has four stages: detect the discrepancy in your reports, assemble evidence, file the claim through Seller Central, and chase it through rejections until the credit posts.
Almost every company in this market claims to do all four stages. In practice they differ sharply at stage three and four, because detection is a data problem while recovery is a labor and persistence problem. That difference is where most seller disappointment comes from, and it is the lens to apply to every comparison below.
The Four Types of Providers
Contingency reimbursement firms
These companies recover funds in exchange for a share of what they collect, often in the 15 to 30 percent range of recovered value, though rates vary by provider and volume. Their strength is alignment: no recovery, no fee. Their weakness is focus — high-volume catalogs get efficient attention, while smaller accounts may land at the bottom of the queue.
Software tools
Audit tools connect to your Seller Central data, flag discrepancies, and sometimes generate pre-filled claim forms. They are the cheapest per finding and the fastest at detection. But a tool cannot attend a case response at 4 p.m. or re-argue a rejected claim with better evidence. Someone on your payroll owns everything after the flag.
Full-service agencies with a reimbursement line
Agencies that manage the whole account treat reimbursements as one workflow among many, running it on a standing cadence alongside PPC, listings, and account health. Tim's Amazon Lab works this way — flat $1,000 per month for accounts up to $35K in monthly sales, no long-term contract, with a dedicated account manager rather than a ticket queue. The trade: you are buying breadth, so a pure-play firm may file more reimbursement cases in isolation.
Freelancers and VAs
A trained contractor can run reconciliation and claim work from your reports at an hourly rate. Costs can be attractive, and a good one learns your catalog deeply. The risk is continuity: when the freelancer steps away, the claim pipeline stops with them, and quality control lands entirely on you.
Pricing Models Compared
| Model | Typical structure | Strengths | Watch-outs | Best fit |
|---|---|---|---|---|
| Contingency | Percentage of recovered funds, often roughly 15–30% | No upfront cost; aligned incentives | Rate is only half the math — check the rejection policy and minimum fees | Sellers who want zero fixed cost |
| Software subscription | Monthly fee, usually tiered by order volume or revenue | Cheapest detection at scale; instant visibility | No claim labor; value depends on your team acting on findings | Hands-on sellers with internal ops time |
| Agency retainer | Flat monthly fee covering reimbursements plus other services | Continuous cadence, cross-account context, one accountable owner | You pay for breadth; verify the reimbursement workflow is explicit in the scope | Growing brands that need operations managed, not just audits |
| Freelancer / VA | Hourly or per-claim rate | Low cost; flexible scope; personal familiarity with your catalog | Continuity and quality control depend entirely on you | Small catalogs with simple claim patterns |
Two pricing traps worth naming. First, some contingency contracts count a claim as "recovered" at approval rather than at posting, which changes what you actually pay for. Second, some software requires a paid tier per marketplace or per data volume, and the sticker price rarely survives contact with a real catalog.
Which Type Fits Your Business?
- Under roughly $20K/month, few inbound shipments: start with software plus a few hours a month of your own time, working from a structured FBA reimbursement checklist. The absolute dollars at stake rarely justify a dedicated provider yet.
- Scaling past $35K/month with regular inbound volume: a full-service agency earns its keep, because reimbursement leakage is no longer your only operational leak. One flat retainer that also covers PPC, listings, and account health beats stacking four vendors.
- Large, high-velocity catalogs with complex fee structures: a contingency firm or an agency with a mature reimbursement line — the claim volume justifies dedicated machinery either way.
- Any size, if you enjoy the work: DIY with good tooling is legitimate. Revisit the decision when claim follow-up starts eating days you cannot spare.
Questions to Ask Before Signing
- Which of the four loop stages do you perform, and which do I keep?
- How do you define "recovered" for pricing — approval or posted credit?
- What happens when a claim is rejected, and how many appeal rounds do you run?
- What look-back window will you cover, and what cadence after the initial cleanup?
- Who exactly works my account, and can I reach the same person next month?
- What do you need to see in my reports before quoting anything?
That last question is a filter. A company that quotes confidently before reading your settlement and reimbursement reports is selling a template, not a service.
Red Flags Across All Four Types
- Guaranteed recovery figures. Amazon decides outcomes; nobody can guarantee them in advance.
- Vague scope after the first audit. "We handle reimbursements" without a defined cadence, claim types, and escalation path means the work will quietly stop.
- Pressure to sign long lock-ins. The reimbursement market moves, and Amazon's own policy changes can reshape the work mid-contract. Month-to-month terms keep the pressure on the provider.
- Requests for permissions far beyond reporting and case filing. Recovery work does not require control of your listings or payments.
- No written definition of success. If credits posted is not the metric, expect findings decks instead of money.
FAQ
Are contingency-only FBA reimbursement companies cheaper than an agency?
Cheaper per recovered dollar, sometimes; cheaper overall, rarely, because an agency's retainer covers work beyond reimbursements. If your only need is claim recovery, contingency wins on simplicity. If you also need ads, listings, and account health managed, one retainer usually beats a stack of vendors.
Can I combine a software tool with an agency?
Yes, and it is a reasonable setup: the tool surfaces discrepancies continuously, the agency owns filing and follow-through. Just make sure the division of labor is explicit so no category of finding falls between the two.
What typical results should I expect in the first quarter?
Honest providers refuse to quote results before reading your reports, because recoveries depend on shipment volume, returns rate, and how long the account went unreconciled. Anyone promising a specific figure sight unseen is guessing on your dime.
Do these companies work on Walmart or other marketplaces?
Many have expanded beyond Amazon, and multi-marketplace capability is fine — but verify it is real operational coverage and not a checkbox. The claim paths, windows, and evidence standards differ by marketplace.
How do I switch providers without losing my claim history?
Export your case logs, reimbursement reports, and any provider findings documents before the engagement ends. A new provider should start from your evidence history, not re-detect everything from zero — and will if you ask.
