Seller Investigators Review & Pricing (2026)

Seller Investigators

Fee Reimbursement

Seller Investigators is an Amazon FBA reimbursement service, now part of the Carbon6 platform, that helps sellers recover funds lost to inventory discrepancies, fee overcharges, and fulfillment errors. Dedicated Recovery Specialists audit seller accounts, identify eligible claims across categories such as inbound shipments, lost or damaged inventory, customer returns, and weight or dimension errors, and file cases directly with Amazon.

The service focuses specifically on FBA reimbursement recovery rather than broader seller analytics or operations management. It operates on a performance-based model with no upfront or monthly fees and reverses its commission if Amazon later reclaims a reimbursement. Sellers preferring self-service software or needing broader operational tools would need additional solutions.
