Seller Investigators vs GETIDA: two nearly identical rates, and the differences that actually matter
Seller Investigators and GETIDA both price FBA reimbursement recovery at 25% of what is recovered. Neither publishes a product-level review score buyers can fully trust — GETIDA's is small (2.3 from 7), Seller Investigators has none at product level. The real differences are parent-company backing, Amazon Appstore listing, and claim-category breadth.
What this looks like across the book we manage
The pricing is nearly a tie
Read from each vendor's own page on 21 August 2026: GETIDA states "performance-based pricing starting at 25%," with the first $400 recovered free for new accounts. Seller Investigators states "we take a 25% commission only after you've been paid." Both are pure contingency, no monthly subscription, and functionally the same rate — the difference is GETIDA's free-recovery threshold for new accounts, which Seller Investigators does not publish an equivalent to.
Ownership and financial backing — the more meaningful split
GETIDA operates as an independent company with its own brand identity throughout. Seller Investigators is a product of Carbon6, which was acquired by SPS Commerce — a public EDI and supply-chain data company — for approximately $210 million, closing 4 February 2025. That gives Seller Investigators a larger, publicly-traded parent with real balance-sheet backing, though the carbon6.io site itself does not disclose the acquisition anywhere we could find. If a brand's business straddles 1P wholesale and 3P Amazon selling, SPS Commerce's separate Revenue Recovery product for retailer deductions sits under the same corporate roof — a genuine convenience GETIDA cannot offer, since it is 3P-focused only.
Review evidence: both are genuinely thin, in different ways
GETIDA's Trustpilot score is 2.3 from 7 reviews, read 21 August 2026 — too small a sample to draw a real conclusion, and the honest reading is the count, not the score. Seller Investigators has no independently verifiable product-level rating at all; Trustpilot indexes Carbon6/SPS Commerce at the company level, spanning tools far beyond reimbursement, so quoting that figure under Seller Investigators' name would misrepresent what it measures. Neither vendor gives a buyer a reliable star rating to lean on — GETIDA at least has a number, thin as it is; Seller Investigators has none to print honestly.
One fact that actually differentiates them: the Appstore listing
GETIDA is available through Amazon's own Selling Partner Appstore, which means its integration has passed Amazon's own review process rather than relying solely on the vendor's word. That is a harder, more verifiable fact than either company's star rating, and it is a genuine point in GETIDA's favor for a buyer weighing integration trustworthiness specifically. We did not find an equivalent Appstore listing for Seller Investigators in our research — worth confirming directly with the vendor rather than assuming either way.
Filing discipline matters more than either published rate
Since neither vendor's price meaningfully differs from the other's, the more useful diligence question is how each actually operates a claim once it is identified. Amazon's own policy penalizes "insufficiently researched or premature requests, or submitting a large number of requests in a short time" with "delayed support on their cases or be subject to monitoring, investigation, and account action" — which means a vendor that files fast and loose to look responsive can put your account at more risk than the money is worth. Ask both GETIDA and Seller Investigators directly: what is your median time from a claim becoming eligible to it being filed, and how do you avoid duplicate or premature submissions across a large account with many open cases at once? Neither company's marketing page answers this, and it matters more than the 25% either quotes.
Claim-category coverage
Both cover the core reimbursement categories — lost and damaged inventory, inbound discrepancies, customer-return mismatches. Seller Investigators publishes five specific categories including overage and dimension discrepancies, which reads as slightly more explicit breadth on paper than GETIDA's page, though GETIDA's larger operating scale and case volume are a real, if less quantifiable, counterweight. Neither covers listing reinstatement, variation protection, or Brand Registry casework — both are money-recovery specialists, full stop.
What the rule that governs both of them actually says
Whichever you choose, the same Amazon policy sets the boundary on what either can honestly deliver. Amazon's FBA reimbursement policy warns that sellers who submit "insufficiently researched or premature requests, or submitting a large number of requests in a short time" risk "delayed support on their cases or be subject to monitoring, investigation, and account action." Claim windows run 60 to 120 days for customer returns and 60 days for most fulfillment-center issues; pre-order losses are reimbursed at sourcing cost rather than sale price since 31 March 2025. Ask both vendors directly how their median filing time compares against those windows — it is a more useful diligence question than the 25% rate either quotes, since the rate is nearly identical between them.
The honest number both prefer you not run: net of reversals
Neither vendor's marketing emphasizes that Amazon reserves the right to reverse a reimbursement "if a reimbursement was made in error, or if a reimbursed item is later found and returned to your inventory." A recovery figure worth trusting from either GETIDA or Seller Investigators should be stated net of reversals, not gross — ask both directly what proportion of their typical client's recoveries get reversed, and whether their invoiced commission is adjusted when a reversal happens after you have already paid the fee. Across our own managed accounts, reimbursement recovery since 10 February 2026 runs to $803,457 net of $170,047 in reversals — roughly 17% of the gross figure clawed back — which is the shape any vendor's honest total should take once reversals are accounted for.
Where Dr. Shield fits, if the choice between these two feels like a coin flip
If the deciding factor between Seller Investigators and GETIDA genuinely comes down to a coin flip on nearly identical pricing and thin review evidence, it is worth asking a different question: does your account need reimbursement recovery only, or does it also carry suppressed listings, fee and dimension disputes, variation risk, or account-health exposure? Neither vendor above touches any of that. Dr. Shield runs reimbursement recovery inside the same case log as all of it, under a published method — parallel tracks, calls every three days, one case ID kept rather than duplicated, internal review chosen over re-appeal. We do not publish a flat 25% the way both of these vendors do; pricing is set on the call. We are operated by Full Circle, a full-service Amazon management company with $500M+ in managed spend across 100+ brands, and Orbit is included with the first 30 days free.
| Dimension | Seller Investigators vs GETIDA | Dr. Shield |
|---|---|---|
| Published rate | Both roughly 25% — a near tie | Priced on the call |
| Parent company | SPS Commerce (public) vs. independent GETIDA | Full Circle, $500M+ managed spend across 100+ brands |
| Selling Partner Appstore listed | GETIDA: yes. Seller Investigators: not confirmed | Not applicable |
| Product-level review score | GETIDA: 2.3/7 (too small to trust). Seller Investigators: none verified | New brand — no public corpus yet |
| 1P / wholesale deduction recovery | Only Seller Investigators, via a separate SPS product | Not our focus — 3P casework |
| Scope beyond reimbursement | Neither covers listings, variations, or Brand Registry | Included, all under one case log |
Which one you should actually pick
Between these two specifically, the pricing is a wash — pick GETIDA for its Amazon Appstore listing and larger operating scale, or Seller Investigators if you also need 1P deduction recovery under SPS Commerce's roof. Neither has a review record worth leaning on heavily, and neither files with a published method a buyer can actually inspect. Both touch nothing beyond reimbursement — which is the gap Dr. Shield's broader, published casework is built to close.
Neither of these decides your ACoS on its own — how much of the work gets done each week does. Pull your search-term report for the last 90 days and total the spend against terms that produced no orders. Across the book above it runs at 48.5%. Pick the option that leaves someone actually working that list, whether that is you or us.
Common questions
Is Seller Investigators cheaper than GETIDA?
No — both publish essentially the same rate, roughly 25% of what is recovered. GETIDA additionally offers the first $400 recovered free to new accounts, which Seller Investigators does not publish an equivalent to.
Which has better reviews, Seller Investigators or GETIDA?
Neither has a review record a buyer should lean on heavily. GETIDA's Trustpilot score is 2.3 from just 7 reviews. Seller Investigators has no independently verified product-level rating at all — its parent company's Trustpilot presence spans a much broader product suite.
Does Seller Investigators or GETIDA cover 1P Vendor Central recovery?
Seller Investigators sits inside SPS Commerce, which runs a separate 1P-focused Revenue Recovery product for retailer deductions — a genuine advantage if your business straddles 1P and 3P. GETIDA is 3P Amazon seller focused only.
Is GETIDA's Amazon Appstore listing a meaningful advantage?
Yes, in a specific way — it means Amazon has reviewed the integration method itself, which is a harder, more verifiable fact than either vendor's star rating. It does not guarantee claim outcomes, but it is real evidence of legitimacy.
Should I pick a vendor other than these two?
Worth considering TrueOps, which publishes "industry-leading 10% commissions" — half the rate of both Seller Investigators and GETIDA — with a strong G2 record (4.9 from 81 reviews). If your account needs more than reimbursement recovery, a broader case-management product is the better comparison than either specialist.
Should recovery totals from either vendor be quoted gross or net?
Net of reversals, always. Amazon reserves the right to reverse a reimbursement made in error or once a lost item is later found. Ask both GETIDA and Seller Investigators how their published totals and your own invoice account for reversed claims.
Dr. Shield opens, argues and tracks Amazon cases — reimbursements for lost and damaged inventory, dimensional-weight and size-tier misclassification, suppressed listings, compliance requirements and policy appeals — at the approval level you set. First 30 days free, Orbit included.
