Amazon FBA Reimbursement Services in 2026: A Commission, Software, or an AI Agent

An Amazon FBA reimbursement service audits your account for inventory Amazon lost, damaged or failed to return, files the claims for you, and keeps a share of what it recovers, usually between 15% and 25%. In 2026 that offer is worth less than it was two years ago, for three reasons that all come from Amazon: many losses are now reimbursed automatically, the time allowed for manual claims is far shorter, and the amount paid is based on what a product costs to make, not what it sells for.

That does not make the services pointless. It changes the question from "how much is Amazon hiding from me" to "who checks what the automation missed, inside the deadline, at what price". This guide sets out the rules first, then the three ways to do the checking: a service that takes a commission, software that produces a list, or an AI agent that runs the comparison on your own data every week and hands you the cases to file. Commission rates and prices were read on each vendor's own page on 10 November 2026.

How FBA reimbursements work now

Three changes define the current system. All three come from Amazon's own announcements on the Seller Forums.

Amazon pays many losses on its own. In its 2024 announcement for the US store, Amazon said that from 1 November 2024 it would reimburse items lost in its fulfillment centers without a claim, as soon as the center reports the loss, and that "almost all" warehouse lost and damaged cases and customer return cases would be reimbursed proactively. Removal claims still have to be filed by hand (Amazon Seller Forums).

Manual claim windows are short. The same announcement set these windows for the US store, effective 23 October 2024:

Before that change, sellers could go back 18 months. The dates are not the same in every store: a second edition of the announcement on the same forum, which does not name its store, gives a customer return window of 45 to 105 days and a start date of 15 January 2025 for proactive reimbursements (Amazon Seller Forums). The announcement does not cover claims for shipments to Amazon, which have their own window. Check the FBA inventory reimbursement policy page in your own Seller Central before relying on any date.

The payout is based on manufacturing cost. Since 10 March 2025, inventory lost or damaged before a customer orders it is reimbursed at its manufacturing cost: what you pay a manufacturer, wholesaler or reseller for the product, or what it costs you to produce, excluding shipping, handling and customs duties. You can enter your own cost in the Inventory Defect and Reimbursement portal; if you do not, Amazon applies its own estimate. Items lost or damaged after a customer order are still reimbursed at the sale price minus fees (Amazon Seller Forums). Amazon staff also call this figure the sourcing cost, and say a valuation can be disputed through Contact Us within 60 days of the reimbursement (Amazon Seller Forums).

The first reimbursement task in 2026 costs nothing: enter your real product costs before Amazon estimates them for you.

What is still worth claiming

With automation covering the simple cases, the money left on the table sits in a few places:

• Losses the automation missed. Amazon itself says to file manually when no automatic reimbursement arrives.
• Customer returns. Orders refunded where the unit never came back, came back as the wrong item, or was restocked as unsellable when it was not.
• Removal orders. Units that left a fulfillment center and never reached you. These are never automatic.
• Shipments to Amazon. Units you sent that were never received.
• Fee errors. Fulfillment fees charged on wrong weights or dimensions.
• Valuation. Reimbursements paid at an estimate below your real manufacturing cost.

The last one is new, and it does not need a claim hunter. It needs your cost data entered correctly once.

Reimbursement services: someone else files, for a commission

What to look for: the commission and what it is charged on, which claim types are covered, whether you can see each case, and how the service handles Amazon's short windows. Ask one more thing now: does the commission apply to money Amazon would have paid automatically anyway?

Sources, all read 10 November 2026: Getida, Seller Investigators, Helium 10, Threecolts.

A few details from those pages are worth knowing. Getida lists a dozen claim types, including inbound shipments, lost removal orders and fulfillment fee overcharges, and says its own staff manage the cases; you may still be asked for proof of ownership or delivery. Seller Investigators assigns case managers who file and appeal, with a dashboard that logs each case. Helium 10's page says the service audits the last 18 months of FBA transactions, which is longer than most of Amazon's current windows allow, and its FAQ quotes a 15% fee where the plan table says 18% for Platinum, so confirm the rate before you switch it on. Threecolts ties the lowest rate, 5%, to its largest plans (Reseller Pro at $199 a month and Brands 10K at $1,199).

The arithmetic is simple. On $10,000 recovered in a year, a 25% commission is $2,500, 15% is $1,500 and 5% is $500. A service earns that when it finds claims you would not have filed. It does not when most of the recoveries are ones Amazon was paying anyway, so ask for a breakdown by claim type after the first quarter.

Reimbursement software: the tool finds, you file

What to look for: a report that lists the specific units and the reference numbers a case needs, and a check of payout value against your product cost.

• sellerboard. Its plans cost $19 to $79 a month ($15 to $63 billed yearly) with a one-month free trial. The site says the tool lets you "find FBA errors and request your money back directly through Seller Support", and that it can flag cases where Amazon reimbursed less than your cost of goods (sellerboard, read 10 November 2026). There is no commission. You open the cases.

This is the cheapest paid route by a wide margin for a single account. The cost is your time: someone has to run the reports on a schedule and file within the windows above.

The agent route: an AI assistant audits your own data

Everything a service audits comes from reports you already own: the reimbursements report (what Amazon has paid, with a reason for each row), the inventory ledger (every movement in and out of a fulfillment center), returns, removal orders and inbound shipments. The audit is a comparison between them, repeated on a schedule, against windows that Amazon has written down. That is close to the ideal job for a seller-side AI agent: the inputs are structured, the rules are public, and the cost of being late is known. Claim services built a business on sellers not having time for it. An agent does not get bored in week three.

What the agent needs is the reports in one place and permission to read them. What it gives back is a dated list: these units, this reference, this window closes on this day.

• DataDoe. A data layer, not a reimbursement service. It keeps the FBA reimbursements report, the inventory ledger in summary and in per-event detail, returns, removal orders, removal shipments, inbound shipments and settlements in one schema, among 130+ tables, and connects them to Claude, ChatGPT or another AI client. The price is $97 a month with a 14-day trial. You can ask which products lost units in the last 60 days with no matching reimbursement, or which refunds from 60 to 120 days ago have no return received. It does not file claims for you and has no claims team; the cases are opened by you in Seller Central. DataDoe's guide to FBA reimbursements walks through the comparison, and its explainer on returns versus refunds covers why the two drift apart.
• Seller Central reports, by hand. Free. Download the reimbursements and inventory ledger reports each month and compare them in a spreadsheet. Workable for a small catalog.
• Amazon's Seller Assistant. Free inside Seller Central; it can look into inventory problems and open support cases for the account you are logged in to.

What an agent can and cannot do here

• It can compare stock movements with payments, sort the gaps by which window closes first, check each payout against your manufacturing cost, net off reversals, and draft the case text with the references Amazon asks for.
• It can run on a schedule. Always-on assistants can repeat the same audit weekly and report only what changed, which matters when the window is 60 days.
• It cannot supply proof it does not have. Invoices, proof of delivery and supplier documents still come from you.
• It should not file on its own yet. Opening a case is a statement to Amazon on your account's behalf, so a person reads the draft and submits it. The reasons are in our guide to AI agents for ecommerce, in the section on guardrails.

The honest limit of this route used to be discipline: with a 60-day window on warehouse losses, an audit run once a quarter is already late. A scheduled agent removes most of that problem, but someone still has to read its list and file. If nobody on the team will, a commission is cheaper than a missed deadline. If someone will, the agent route costs a flat fee however much you recover, and the same data answers other questions the rest of the month.

Which route fits

• Small catalog, low FBA volume: enter your manufacturing costs, check the reimbursements report monthly, and stop there.
• One account, steady volume, someone with an hour a month: software, or an AI agent on your own data. A flat fee beats a percentage quickly.
• Large catalog, no time, or a backlog of removals and inbound discrepancies: a service. Compare the commission, ask what it is charged on, and review the claim mix after three months.
• Several accounts, an agency, or a finance team that wants the numbers anyway: a data layer with an AI client, and a service only for the claim types you do not want to handle.

Whichever you pick, watch for reversals. Amazon takes a reimbursement back when a lost unit is found or a late return arrives, so recovered totals should be counted net.

How we chose

Every service and tool here states its price or commission on its own site, read on the date given. We did not count affiliate programs and did not include vendors whose pricing pages could not be read. Reimbursements are one line in a seller's toolset; the rest is in the best Amazon seller tools by job, and the stock side is in Amazon inventory management software. Reimbursement audits are one of the first back-office jobs to move from outsourced staff to agents; the wider picture is in AI agents for ecommerce.

FAQ

Are Amazon FBA reimbursement services worth it?

They are worth it when they find claims you would not file yourself, mainly removals, inbound shipments, customer returns and fee errors. They are worth less than before 2024, because Amazon now reimburses many warehouse losses automatically.

How much do FBA reimbursement services charge?

On 10 November 2026, published commissions ran from 5% on Threecolts' largest plans to 25% at Seller Investigators, with Getida starting at 20% and Helium 10 at 15% to 18% on top of its subscription.

How long do I have to file an FBA reimbursement claim?

For the US store, Amazon's announcement gives 60 days for fulfillment center losses, 60 to 120 days after the refund for customer returns, and 15 to 75 days for removals lost in transit. Other stores differ, so check the policy page in Seller Central.

How does Amazon calculate the reimbursement amount?

Since 10 March 2025, inventory lost or damaged before a customer order is reimbursed at manufacturing cost, using your figure if you entered one and Amazon's estimate if not. Losses after a customer order are paid at the sale price minus fees.

Can an AI agent handle FBA reimbursements?

It can do the audit: compare the inventory ledger with the reimbursements report, list what looks unpaid, rank it by deadline and draft each case. Filing and supplying documents still need a person, and that is the safer split today.

Can software file reimbursement claims for me?

Software and data tools find the gaps; filing is done by you or by a service's staff. DataDoe, for example, lists what looks unreimbursed but does not file cases.
