Amazon FBA sellers leave real money on the table: units marked lost or damaged in the warehouse that were never reimbursed, and customer returns that never came back but still got refunded. Recovery services charge 10-25% of whatever they find. This is a flat fee instead.
Send one month of three reports pulled from Seller Central (same date range): Inventory Ledger (Adjustments), FBA Customer Returns, and Reimbursements. I cross-check them and hand back a clear list of exactly which cases Amazon still owes you, with the evidence you need to file each one yourself.
What you get:
One month, one flat fee. If your reports show nothing owed, you get told that too, not a runaround.
No Amazon affiliation. You keep 100% of what you recover. This is a research and reconciliation service, not a filing service.
