Seller Investigators operates on a pay-as-you-go performance model: there are no sign-up fees, no recurring charges, and a 25% commission is deducted only when funds are actually recovered from Amazon. The service starts with a free, no-obligation reimbursement audit delivered within 48 hours, and it includes a free Weight and Dimensions tool that flags FBA fee overcharges before they compound. Seller Investigators issues no promotional codes, so the risk-free audit and the free monitoring tools are the real levers for cutting costs.
Start With the Free 48-Hour Reimbursement Audit Before Paying Anything
Seller Investigators runs a free, no-obligation reimbursement audit and returns results within 48 hours, letting FBA sellers see potential recoverable funds before committing a single dollar. According to Seller Investigators's official terms, the service charges no sign-up fee and no fixed recurring cost; a 25% commission applies only after money is successfully recovered back to an FBA account.
This matters because the audit removes the usual upfront gamble of hiring a reimbursement service. Sellers who are uncertain whether Amazon owes them anything can confirm the recoverable amount first and pay only against funds that actually land in their account. Requesting the audit through selleriinvestigators.com is the primary way to test the service, since no promo code or discount exists to lower a cost that is already zero until recovery happens.
Catch Amazon Fee Overcharges With the Free Weight and Dimensions Tool
Seller Investigators provides a free Weight and Dimensions tool that tracks FBA shipments and alerts sellers to potential Amazon fee overcharges. According to Seller Investigators's official FAQ documentation, Amazon frequently miscalculates tier sizes or product weights, and those errors translate into overcharges applied per unit shipped.
Because fee errors recur silently on every affected unit, catching them early prevents a small per-unit miscalculation from accumulating across an entire inventory run. The tool carries no separate service fee, so monitoring dimensional accuracy costs nothing beyond the time it takes to review the alerts. Running shipments through this tool gives FBA sellers a way to dispute fee discrepancies proactively rather than discovering them after months of overbilling.
