Short answer: Seller Investigators is a managed FBA reimbursement recovery service, owned by Carbon6 since 2022, that charges 25% of what it recovers with no sign-up fee and no free recovery allowance — its FAQ adds that “the recovery fee is negotiable based on the size of your business” (sellerinvestigators.com/frequently-ask-questions/, data checked 2026-08-15). On headline rate it matches GETIDA and Refunds Manager exactly, so the rate is not the decision. Two other terms are. It is the only one of the three to publish what happens when Amazon claws a reimbursement back — the clause its 2026 reviewers are angriest about. And its Terms of Service carry a fee sentence word-for-word identical to Refunds Manager’s, which limits how much weight that contract wording can bear.
What Seller Investigators charges, in its own words
There is no pricing page: /pricing/ and /pricing both 404, the sitemap lists no pricing URL, and the /affordable/ URL in that sitemap redirects to the homepage (checked 2026-08-15). The commercial terms are prose, spread over three pages.
| Term | What Seller Investigators publishes | Source page (checked 2026-08-15) |
|---|---|---|
| Commission | “only pay a 25% commission fee when your money is back with you” | homepage |
| Commission, contract wording | “We charge 25% of all refunds from the day you sign up for all cases we open” | /terms-and-conditions/ §7 |
| Rate flexibility | “The recovery fee is negotiable based on the size of your business” | /frequently-ask-questions/ |
| Sign-up cost | “There is no sign-up fee or fixed charges” | /frequently-ask-questions/ |
| Free allowance | None published; the free offer is an audit, not a fee waiver | homepage |
| Billing | Invoice “on the 1st and 15th of each month and after 1 day, we’ll charge your debit or credit card” | /frequently-ask-questions/ |
| Cancellation | “no long-term contacts”, email to cancel; “will take effect immediately” | /frequently-ask-questions/, /terms-and-conditions/ §8 |
| Clawbacks | “When Amazon reverses a reimbursement, Seller Investigators will reverse the fee on the next invoice” | /frequently-ask-questions/ |
Three rows are worth more than the headline number.
“Negotiable” is the only published rate flexibility in this category. Refunds Manager advertises a “Fixed 25% commission rate”; GETIDA says “performance-based pricing starting at 25%”, which points upward rather than down. A 2022-11-19 Trustpilot reviewer put the range as “18-25%”, consistent with sub-sticker rates existing — but no volume table is published, so treat it as something to ask for, not something you have.
Billing is a card charge, not a deduction. Amazon deposits recovered funds into your Seller Central account; Seller Investigators then invoices and charges your card, on a cadence its Terms describe differently again (“a bill twice a month… charged for the previous week’s invoice”, /terms-and-conditions/ §7). The commission is an outflow you fund yourself, on a schedule that is not your Amazon disbursement schedule.
The contract sentence is not its own. Section 7 reads: “We charge 25% of all refunds from the day you sign up for all cases we open.” That is word for word the sentence in Refunds Manager’s Terms of Service — as are its cancellation and account-access clauses. Two unaffiliated competitors are running the same terms template, so the ambiguity flagged in the Refunds Manager review — does “for all cases we open” exclude claims you file yourself, or is it only a start date? — is inherited here unresolved. It is still the largest cost variable in either agreement, and still needs settling in writing before you sign up.
The clawback credit: the one term no competitor publishes
Amazon sometimes reverses a reimbursement it has already paid, leaving you having paid a commission on money you no longer have. Of the three services here, only Seller Investigators publishes what happens next:
“A Clawback is when Amazon takes back money refunded to sellers as a reimbursement. When Amazon reverses a reimbursement, Seller Investigators will reverse the fee on the next invoice.” (/frequently-ask-questions/, checked 2026-08-15)
Its FAQ goes further and claims to be “the only company that credits the fees paid when Amazon reverses a reimbursement” — a vendor claim about competitors, not a verified one. The narrower half we can confirm: neither GETIDA’s nor Refunds Manager’s published pages address reversals at all.
Read the wording closely, though, because it says credit, not refund — and that distinction is the substance of both 2026 complaints in our review corpus. A 2026-02-10 Trustpilot reviewer: “They don’t refund Amazon reversed reimbursements. Over £4k of their reimbursments have been reversed which I now have to manually request a refund for… I’ve also been told they don’t actually refund this only credit it.” A 2026-03-17 reviewer, 1 star after years as a customer: “They have now changed their policy and don’t refund for Reversed reimbursments!!! … They use it as a credit!!! Insane. They have my money and wont give it back!”
Both accounts and the official clause describe the same mechanism. A credit against the next invoice is worth full value while recoveries continue and nothing the moment they stop — which is when a reversal is most likely to matter, because a seller winding down has no future invoice to offset. Neither reviewer’s figure could be attributed to a fee or a reimbursement, and one alleges a policy change our sources cannot date. Ask whether an unused credit is refundable in cash on cancellation. Nothing we read on 2026-08-15 answers that.
What 25% costs, next to GETIDA and Refunds Manager
The three converge on the same rate, so the arithmetic is nearly identical. This table is our own calculation applied to each vendor’s published rate, not a quote from anyone.
| Recovered in a year | Seller Investigators (25%, no allowance) | Refunds Manager (flat 25%) | GETIDA (year one, after first $400) |
|---|---|---|---|
| $2,000 | $500 | $500 | $400 |
| $10,000 | $2,500 | $2,500 | $2,400 |
| $25,000 | $6,250 | $6,250 | $6,150 |
| $50,000 | $12,500 | $12,500 | $12,400 |
The $100 gap is GETIDA’s first-$400 allowance, a first-year artefact only; from year two all three cost the same. Anyone choosing on price alone is choosing on $100.
For sizing, the vendor supplies its own anchor: the reimbursement calculator on its homepage, at the default position it renders with, shows $2,000,000 of trailing twelve-month sales producing “$20,000” of annual potential recovery — 1% of GMV, so a $5,000 fee. Treat that as a marketing assumption, not a benchmark, and remember recoveries are lumpy: one lost inbound shipment can be most of a year’s total and is not weeks of work.
The self-filing path has tooling of its own. ReimburseOps takes a Seller Central reimbursements CSV you export yourself, runs audit rules over it and returns a prioritised list of flagged records — free tier at $0 with the first 3 flagged records shown in full, Pro at $19/month, no commission and no Amazon account connection. It does not file claims, which is precisely the labour any 25% pays for; it does answer, without granting account access, whether your flagged total is a $500 problem or a $50,000 one.
What it files, and the window its own FAQ still describes
The published claim coverage is the most granular of the three, and it is where the service differentiates rather than on price. Its FAQ and homepage list the same set (checked 2026-08-15):
| Bucket | Claim types listed |
|---|---|
| Inbound Shipments | Canceled shipments · Receiving discrepancy · Damaged by carrier |
| Lost / Damaged Items | Lost in transit · Lost in the warehouse · Damaged in the warehouse · Disposed by Amazon · Unfair reimbursement |
| Customer Returns | Not returned within 60 days · Refunded more than paid · Wrong item returned · Chargeback not refunded |
| Overages & Discrepancies | Removal orders · Incorrect weights and dimensions · Overcharged orders |
Removal orders matter more than any other line in it. Amazon announced that from November 1, 2024 it would proactively reimburse FBA items lost in its fulfillment centers, while “all removal claims will still need to be filed manually” (Amazon Seller Forums , checked 2026-08-15). Removals are a large part of what is left to recover, and Refunds Manager’s published FBA list does not include them.
The same FAQ, however, describes eligibility windows that predate that announcement: “Items that are lost or damaged more than 30 days ago in the past 18 months” and “Amazon-miscounted inbound items from inbound shipments in the past 9 months.” Amazon’s current rule in the same announcement is that a fulfillment centre operations claim “must be submitted no later than 60 days after the item was reported lost or damaged.” The 18-month historical sweep is what this category was built to sell, and much less of it survives that deadline. The GETIDA review covers the shift in full; the point here is narrower — that lookback text describes the old environment, so do not size your expected recovery from it.
One published window does look adapted. On customer returns, the FAQ says that because Amazon “often” processes returns on day 64 rather than day 60, “we pushed back our case filing to day 100”, then follows up on the roughly 5% of cases missed — a specific operating decision the competing FAQs do not offer.
“We do not automate any claim submissions”
The clearest answer to the question of how this differs from an automated scanner comes from the vendor’s own FAQ, quoted here in full because the wording is the whole point: “No. In accordance with Amazon’s Terms of Service, we do not automate any claim submissions. Your recovery specialist reviews each potential claim and manually submits quality claims with accurate data.”
Around that, the FAQ says each client is assigned two Recovery Specialists who run weekly audits, and that data is accessed “through Amazon’s secure API” and stored in AWS. On compliance the site says of itself that its “FBA reimbursement process and tools fully comply with Amazon’s terms of service”. That is the vendor’s statement about its own compliance; we found no Amazon page addressing this service, and the Selling Partner Appstore listing its homepage links to did not render for us on 2026-08-15.
The trade-off is real either way. Manual review by a named specialist is slower and headcount-bound; it is also why the service can pursue the “$50 or $100 reimbursements” its FAQ says competitors skip. A long tail of small discrepancies argues in its favour; a handful of large ones means paying a percentage for labour you do not need much of.
What sellers complain about
Our review corpus holds seven Trustpilot reviews for this service, six negative, spanning 2020 to 2026. The two 2026 items are covered above; the rest cluster on two themes.
Onboarding and communication. A 2023-03-29 reviewer: “It’s been a month and a half and no progress on our product restriction issues after promising during the sales process that this is one of their specialties… They seem backlogged so things are moving veeeery slowly…” A 2023-03-22 reviewer: “Poor communication; lack of follow through. Didn’t deliver on what they promised.”
Feature gaps against GETIDA, as of 2023. The most detailed review, dated 2023-04-14 from a seller who had moved over from GETIDA, listed three: “Weight and Dims doesn’t yet work for UK/EU (it does with Getida)”, “Weight and Dims isn’t automated”, and having to run “2 separate accounts for UK/EU and USA/CA” — the last said to be getting fixed. That is a three-year-old snapshot and the marketing since names Weights & Dimensions as a headline feature, so verify all three during your free audit.
Value against automatic reimbursement. A 2022-11-19 reviewer: “Too expensive. 18-25% for something that can be done by sellers themselves.” The 2026-03-17 reviewer put it more sharply: “Amazon now does this job automatically so there’s little need to use them but they owe me so much money.”
The eight-dimension scorecard
We evaluate every Amazon tool on eight dimensions — Accuracy, Ease, Depth, Automation, Team Fit, Support, Pricing, Stage Fit (see our scoring methodology ). This is built from published pages checked 2026-08-15 and the dated reviews above — not a controlled hands-on benchmark.
- Accuracy — Unverified, vendor-reported only. “Recovers 30% more money than our competitors” carries no methodology or period.
- Ease — Strength. Free audit, no sign-up fee, and the filing work stops being yours.
- Depth — The best-published claim list of the three, removal orders included.
- Automation — Deliberately absent on filing. Detection is systematic; submission is manual by policy.
- Team Fit — Two named specialists per account, nothing published on seats.
- Support — The weakest area in the public record, on responsiveness rather than recovery.
- Pricing — Matched on rate, distinguished on terms. No allowance, but the only published clawback clause and the only published route to a negotiated rate.
- Stage Fit — Mid-size and up, where a negotiable rate and per-account specialists are worth most.
Who should use it, and who should not
Use it if your recovery profile is a long tail of small discrepancies, removal orders are a meaningful part of it, or your volume is large enough that “negotiable” is a real lever. Get the rate quoted before onboarding, not after.
Consider it if clawbacks have burned you elsewhere — it is the only one of the three with a published clause — as long as you first settle the credit-versus-refund question below.
Look elsewhere if you want to size the opportunity before granting account access, or if your recoveries are few and large. See our reimbursement primer , GETIDA alternatives for the wider field, and the inventory and operations hub.
What we could not verify
Seller Investigators publishes no pricing page, no volume-rate table, no minimum invoice, and no statement of whether an unused clawback credit is refundable in cash after cancellation. Its own pages disagree on audit turnaround — the homepage promises one “in just 48 hours”, the FAQ says “within 3 business days” — and on service regions, given variously as US/UK/EU/APAC (homepage), US, UK, EU, Asia and the Middle East (About), and North America, Europe, India, Australia and the UAE (FAQ). The “95.9% success rate” and “$100 million recovered” figures circulating in third-party write-ups appear on no Seller Investigators page we read on 2026-08-15. No service was tested hands-on; every figure here is a published claim or a seller’s own dated account.
Frequently Asked Questions
How much does Seller Investigators cost? 25% of what it recovers, with no sign-up fee and no fixed charges. Its Terms of Service state: “We charge 25% of all refunds from the day you sign up for all cases we open” (/terms-and-conditions/ §7, checked 2026-08-15). No free recovery allowance is published, and the FAQ adds that the rate “is negotiable based on the size of your business.”
Is it the same company as GETIDA? No. Seller Investigators has been owned by Carbon6 since 2022, joining, per its About page, “as its flagship reimbursements service”; GETIDA is not owned by Carbon6, but it took a strategic investment from SIB Holdings in 2022. Carbon6’s pricing page publishes no price for it — that page is a three-question quiz ending in a call booking (carbon6.io/pricing, checked 2026-08-15).
What happens to the commission if Amazon reverses a reimbursement? Its FAQ states that “Seller Investigators will reverse the fee on the next invoice” — a credit against future invoices rather than a cash refund, which is the substance of two 1-star reviews from February and March 2026. Confirm in writing what happens to an unused credit if you cancel.
Does it file claims automatically? No, by its own statement: “In accordance with Amazon’s Terms of Service, we do not automate any claim submissions. Your recovery specialist reviews each potential claim and manually submits quality claims with accurate data” (checked 2026-08-15).
