Identifying Fee Discrepancies

Analyzing fee data is just the first step. To uncover errors, you’ll need to dig into Amazon's fee rules and product size classifications.

Checking Amazon Fee Rules

Match the fees you're being charged with Amazon's official FBA fee schedule. Pay close attention to these fee types:

  • Storage fees: Calculated per cubic foot and adjusted seasonally.

  • Referral fees: Based on the product category.

  • Long-term storage fees: Charged for inventory stored over 365 days.

Errors often stem from miscalculations or incorrect classifications.
