Top Amazon FBA Refund Services: Features, Fees & Comparison
The best Amazon FBA refund service for most U.S. sellers is one that audits for free and charges only on money Amazon actually pays. Refunzo does this with a free 21-checkpoint audit and a 15% fee capped at $5,000 per account. Other strong options are GETIDA, Seller Investigators for the longest track records (25%) and sellerboard for sellers who prefer to file themselves.

What Is an Amazon FBA Refund Service?
An Amazon FBA refund service is a third-party provider that audits your Seller Central data, finds inventory and fees Amazon owes you money for, and files or prepares claims to recover it. Most call it "reimbursement" rather than "refund." Amazon uses "refund" for customer returns, so the two terms get mixed up in search.
Services fall into three models. Managed services file claims for you and take a commission. Software tools (sometimes called Amazon reimbursement management software) flag cases and you file them. Hybrids offer both. The typical problems they recover include:
- Lost or damaged inventory
- Inbound shipment shortages
- Customer returns that never came back
- FBA fee overcharges from wrong dimensions
- Removal order losses
How Much Money Does Amazon Owe FBA Sellers?
Amazon FBA sellers typically lose about 1% to 3% of annual revenue to unreimbursed errors. That range is cited by TrueOps and by Threecolts, which analyzed more than 200,000 seller accounts. For a seller doing $1 million a year, that is $10,000 to $30,000. A seller at $5,000 a month (about $60,000 a year) is looking at roughly $600 to $1,800.
Amazon's own automatic reimbursements cover simple, single-step losses. They don't reliably catch multi-step discrepancies, underpayments against your real cost, or cases that need carrier proof of delivery. Refunzo's 2025 tools comparison goes deeper on how these gaps arise. Ongoing monitoring catches more than a one-time audit because new discrepancies appear every week.
How Did Amazon's 2025 Policy Change Affect FBA Reimbursements?
Since March 2025, Amazon reimburses lost and damaged FBA inventory at your manufacturing cost, not your selling price, and most claim types have roughly a 60-day filing window. Both changes reduce what sellers recover and shorten how long they have to act.
If your cost data in Seller Central is blank or stale, Amazon substitutes its own estimate, which is typically lower than your real cost. A $30 product that costs you $9 to make now reimburses closer to $9 than $30, assuming your cost data is accurate. Refunzo's 2026 policy reference tracks the window by claim type. Amazon updates these rules, so check Seller Central help before filing anything time-sensitive.
Two practical steps follow. First, update documented costs for every active ASIN. Second, audit monthly, not yearly, because a claim older than the window is usually lost.
What Are the Best Amazon FBA Refund Services in 2026?
The best services combine a free audit, a transparent fee and compliant claim filing through Seller Central. The ranking below weighs fee structure, filing model, track record, claim coverage and fit by seller size. It is not a head-to-head recovery test, because no vendor publishes comparable recovery data.
1. Refunzo: Best for a Free Audit and a Capped Fee
Refunzo is an Amazon FBA reimbursement platform by eStore Factory that runs a free 21-checkpoint reconciliation and charges 15% only on money Amazon pays, capped at $5,000 per account. You can file every case yourself, hand off all of them, or split the work.
- Model: DIY at $0 or managed at 15% (capped). No monthly fee, setup fee or contract.
- Standout: The cap. At $50,000 recovered, Refunzo's fee is $5,000 versus $12,500 at 25%. Fees are charged only after Amazon pays your bank.
- Managed filing: Refunzo logs and substantiates each Amazon case, follows up and retrieves proof of delivery from your carrier.
- Trust signals: Refunzo is an Amazon SPN verified service provider.
- Watch-out: Refunzo's own pricing page says that if you recover under roughly $2,000 a year, filing yourself or using a flat-fee tool costs less than any commission model, including Refunzo.

2. GETIDA: Best for a Long-Established Managed Service
GETIDA is a fully managed service that charges 25% of recovered funds and reviews up to 18 months of transactions. Its case managers file and track claims, and it waives the commission on the first $400 for new accounts.
- Strengths: Large operation, broad claim types and hands-off filing.
- Watch-out: 25% is at the high end, with no published cap. It's a better fit when you want zero involvement and recovery volume is modest.
3. Seller Investigators (Carbon6): Best for Weekly Human Audits
Seller Investigators assigns two Recovery Specialists to audit your account weekly and charges 25%, negotiable for large accounts. It states it has recovered over $100 million with a 95.9% success rate on filed cases, and it offers a free initial audit. Those figures are the vendor's own and are not independently verified.
- Strengths: Human review, strong compliance focus and a policy of returning its commission if Amazon claws a reimbursement back.
- Watch-out: Manual review can be slower on routine claims.
4. Refully: Best for a Mid-Priced Managed Service
Refully charges 18% with a dedicated account manager and a live claims dashboard. New accounts get the first $1,000 in reimbursements free. At 18% it sits between TrueOps and the 25% group, though it has less public track-record data.
5. Helium 10 (Refund Genie and Managed Refund Service): Best for Existing Helium 10 Users
Refund Genie is a DIY reimbursement tool included in Helium 10's higher plans, and the separate Managed Refund Service charges 15% to 18% depending on plan. Refund Genie produces report-based cases that you file yourself in Seller Central. A Platinum plan starts around $79 a month.
- Watch-out: It only makes sense if you already pay for Helium 10. Bundled pricing makes cost comparisons harder.
6. Threecolts Margin Pro: Best for Enterprise-Scale Accounts
Threecolts Margin Pro charges a success-based fee of 15% to 25% and also covers vendor deductions and shipping cost recovery. It is built for high-SKU, multi-marketplace operations. Smaller sellers usually don't need the extra scope.
Also Considered
- Seller Presto: A UK-based Amazon agency that offers FBA reimbursement on a commission basis, with no published rate on its service page.
- AMZRefund and DimeTydSellers: Both charge 25% and file claims manually. DimeTydSellers throttles submissions (commonly 5 to 10 a day) to avoid looking excessive to Amazon.
- Refunds Manager: One of the longest-running services, operating since 2012, at about 25%.

How Much Do Amazon FBA Refund Services Cost?
A commission model costs you a percentage of whatever the service recovers, so total cost grows with your recovery volume unless the service caps the fee. The same recovery produces very different fees depending on the rate.
| Amount recovered | 15% (Refunzo, capped at $5,000) | 18% | 25% |
|---|---|---|---|
| $10,000 | $1,500 | $1,800 | $2,500 |
| $33,000 | $4,950 | $5,940 | $8,250 |
| $50,000 | $5,000 | $9,000 | $12,500 |
| $100,000 | $5,000 | $18,000 | $25,000 |
Free allowances matter at small volumes. A $1,000 free allowance can erase the whole fee for a seller who recovers $1,000 in total. Check Refunzo's pricing to model your own numbers.
Should You Use Software, a Managed Service or a Hybrid?
Choose software if you have time and low recovery volume, a managed service if you want zero filing work, and a hybrid if you want to file easy cases yourself and outsource the hard ones.
| Software (DIY) | Managed service | Hybrid | |
|---|---|---|---|
| Who files claims | You | The provider | You and the provider |
| Cost model | Flat subscription | Commission | Free or flat fee plus commission |
| Best for | Under about $2,000/year recovered; sellers with spare time | Larger recoveries; no time | Mixed case complexity |
| Example | sellerboard, Refund Genie | GETIDA, TrueOps | Refunzo |
Refunzo's manual vs. automated reconciliation guide covers the tradeoffs in more depth. Complex cases are where managed services earn their fee. Shipment shortages need carrier proof of delivery, and multi-report discrepancies need evidence assembled across reports. If you want a full-service team that also handles your wider account operations, eStore Factory's FBA reimbursement service is the done-for-you route.
How Do You Choose the Right Amazon FBA Refund Service?
Pick the service by matching its fee model to your annual recovery, then check its compliance, coverage and reversal policy. Use these five steps.
Step 1: Run a free audit first
Run a free audit with two or three vendors to see what Amazon owes you. Refunzo, Seller Investigators, TrueOps and Threecolts all offer free audits or scans. Compare the estimates, not the sales pitches.
Step 2: Estimate your annual recovery
Multiply your annual FBA revenue by 1% to 3%. If the result is under about $2,000, use software or file yourself. Otherwise, use the cost table above.
Step 3: Verify Terms of Service compliance
Ask how claims are filed. The service should use Seller Central or SP-API with proper permissions, not unauthorized automation. Prefer read-only data access and ask whether claims are throttled or reviewed by a person.
Step 4: Check reversal and claw-back handling
Amazon sometimes reverses reimbursements. Ask whether the fee is refunded if that happens. TrueOps and Seller Investigators say they do this. Refunzo charges only after Amazon credits your bank, and calculates the fee on the amount actually paid.
Step 5: Fix your cost data
Update documented costs in Seller Central for each ASIN. Services can only claim what Amazon will value, so accurate cost data raises every payout.
Not sure where to start? Refunzo's FBA account audit guide walks through the manual process, and the list of common reimbursement issues shows what to look for.
What Red Flags Should You Avoid in a Refund Service?
Avoid any service that asks for your Seller Central password, hides its fee structure or promises a guaranteed recovery amount. Amazon's reimbursement outcomes depend on evidence and claim eligibility, so no provider can guarantee a number.
Other warning signs:
- No stated Terms of Service compliance
- Large upfront fees
- Long contracts with no exit
- No answer on what happens if Amazon reverses a payout
Frequently Asked Questions
What is an Amazon FBA refund service?
An Amazon FBA refund service audits your Seller Central data for money Amazon owes you, such as lost inventory, damaged units and fee overcharges, then files or prepares claims. Most charge a commission only on recovered funds.
How much does an Amazon FBA refund service cost?
Commission rates run from 15% to 25% of recovered funds. Refunzo charges 15% capped at $5,000 per account, Refully 18%, and GETIDA and Seller Investigators 25%. Software tools like sellerboard charge a flat $19 to $79 a month.
Are Amazon FBA refund services safe for my account?
Reputable services work through Seller Central or Amazon's Selling Partner API and follow Amazon's Terms of Service. Choose providers with read-only data access, transparent filing methods and Amazon Selling Partner Appstore or Service Provider Network listings.
How long do I have to file an FBA reimbursement claim?
Most claim types carry a window of roughly 60 days from the triggering event, such as a shipment closing or a refund being issued. Windows vary by claim type and Amazon updates them, so confirm in Seller Central help.
Is a refund service worth it for small sellers?
It depends on volume. If you expect to recover less than about $2,000 a year, a flat-fee software tool or filing yourself usually costs less than commission. A free audit from Refunzo shows your actual number before you commit.
Can I file Amazon FBA reimbursement claims myself?
Yes. Seller Central lets you open cases directly. The work is finding discrepancies across reports and assembling evidence such as proof of delivery, which is where software or services save time.
What is the difference between FBA reimbursement software and a refund service?
Software flags cases and prepares claim text, and you submit them. A service files and follows up for you. Tools like sellerboard and Helium 10's Refund Genie are software, while GETIDA and TrueOps are services. Refunzo offers both paths.
Why did my FBA reimbursement amount drop?
Since March 2025, Amazon reimburses lost and damaged inventory at manufacturing cost rather than selling price. Missing or outdated cost data lowers it further, because Amazon substitutes its own estimate.
Bottom Line: Which Amazon FBA Refund Service Should You Pick?
The right Amazon FBA refund service depends on how much Amazon owes you and how much of the work you want to do. Run a free audit first. If the number is large, choose a capped or low-commission service. If it's small, file yourself. For most sellers in the $5K to $1M+ per month range, Refunzo is the safest starting point because the audit is free and the fee can never exceed $5,000 per account.
