Seller Interactive review
Worth a conversation about Marketplace / Retail Media once the caveats below are settled.
A real Amazon and Walmart agency with strong claimed scope, but a 44% one-star Trustpilot share and repeated account-health and delivery complaints make the downside unacceptable.
No published price we can link to. We do not estimate one — ask on the call, and see the pricing-transparency line in the scores below.
How it scored
Every dimension is scored against this discipline’s published rubric. Open one to see the claim it was scored on, what the rubric measures there and how much it weighs, and where the evidence came from.
How we scored this
We read the agency’s public record first-hand — its site, pricing, case studies and independent reviews — and score what is checkable: what is published, not how it is phrased. There is no keyword counting or sentiment scoring. The label is a judgment on those facts, which is why each dimension shows the fact that decided it, the band it was judged against, and the sources — so you can check the call, and tell us if you think it is wrong. The full method, and who pays, is on how we vet.

Verdict
CUT despite legitimate marketplace specialization and positive client reports. Seller Interactive publicly offers full account management, PPC, listings, logistics, brand protection, and Walmart services.
The adverse pattern is too material to average away: Trustpilot shows 44% one-star reviews, and multiple detailed reviews allege delayed or incomplete work, staff churn, suppressed or removed listings, rising ad costs, poor files, and trademark-related account damage. Treat those as allegations, not adjudicated facts, but do not grant access to a revenue-critical marketplace account without extraordinary references and contractual safeguards.

What other platforms say
Feedback is sharply polarized. Positive buyers cite responsive teams and sales gains; negative buyers repeatedly describe delay, poor execution, listing suppression, ad-cost deterioration, staff churn, and refund or file-handoff disputes.
These are other platforms' numbers, not ours. We report them because they are part of the picture, and we do not average them into our score — our score comes from the published rubric above.
Red flags
- Forty-four percent one-star share on Trustpilot
- Repeated listing-suppression and policy-compliance allegations
- Repeated delay, team-churn, refund, and native-file complaints
- Vendor case claims conflict sharply with a material adverse-review pattern
What we could not verify
- Resolution of specific listing, refund, and IP complaints
- Current team-retention rate and QA escalation process
- Account permissions, native-file ownership, termination, and indemnity terms
