Amazon permanently ended prep services Jan 2026. Now every defect costs $0.60/unit. Our Chrome extension tells you exactly what prep each ASIN needs — before you ship.
Since Amazon ended seller prep services, every incorrectly prepped unit costs you real money.
Amazon’s new defect fee jumped from $0.02 to $0.60 per unit — an up to 80x increase overnight.
Prep requirements are scattered across dozens of Amazon Seller Central help pages. Miss one and you pay.
Amazon no longer covers damages from incorrect prep. Every defect is your cost, every time.
Use this calculator to estimate your potential losses from incorrect FBA prep.
Industry average is 10-15% for sellers without prep verification tools.
