Seller Interactive review

CUT

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.

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.

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.
