Amazon doesn't tell sellers when it owes them money — and it can't tell you if a SKU is actually profitable, because it never knows what you paid. fbaleaks finds both. Upload a CSV with your SKUs, sale price, and cost, and it flags every unit lost to warehouse damage or fee errors, generates the reimbursement claim, and gives you a Keep / Reprice / Kill call on every SKU before you reorder. No subscription. Buy it once. Everyone else rents you the tool.
