The Problem
FBA Discrepancies Are Constant. The Window to Claim Them Is Not.
Amazon's warehouses check in billions of units a year. Errors happen across every stage — receiving, storage, returns, disposal. Most are correctable. But since January 2025, you have exactly 60 days to identify and file each one.
Since March 2025, claims also require manufacturing cost documentation. Without it, Amazon uses its own cost estimate, which typically lands below your actual production cost.
Claims Expire Permanently
After 60 days, unclaimed discrepancies stop being recoverable. Amazon's published policy does not accept filings outside the window.
Documentation Is Now Required
Manufacturing cost evidence must be accurate and current. Generic or missing documentation leads to underpayment or outright denial.
Automation Tools Are Increasingly Rejected
Bulk-submission bots cannot prepare the tailored documentation Amazon now requires.
