Worried that filing reimbursements gets you suspended? Read this first.

The question that stops sellers from claiming money they're owed: will Amazon punish me? Straight answer: filing accurate claims for real discrepancies is normal FBA; what raises flags is the pattern — sudden high volume, the same event claimed twice, or claims fired off automatically without anyone checking.

Some third-party services connect to your account and file aggressively across sellers to maximize commission; it works until it doesn't, and it goes wrong on your account. Costback is the opposite of that risk: you file, not us (you review each case); human pace, not machine-gun volume; we never hold your login; you only file what's real (matched against what Amazon already reimbursed).

The safe way has always been the same: verify, file yourself, one clean case at a time, inside the deadline. Costback just makes the finding fast. Judgment, filing, and pace stay with you.
