Why Sellers Lose 1% to 3% of FBA Revenue to System Leakage
Industry data confirms that 1% to 3% of Amazon FBA annual gross merchandise volume (GMV) is lost to fulfillment center discrepancies: misplaced items (Reason Code M), warehouse damages (Reason Code E), customer returns refunded but never returned to stock after 45 days, and carrier transfer losses.
While Amazon Seller Central provides raw reports, Amazon does not automatically calculate discrepancies for you. Under Amazon's October 23, 2024 policy reform, the statutory claim window was reduced from 18 months to strictly 60 days. If discrepancies are not identified and claimed within 60 days, Amazon permanently forfeits your funds.
