What you receive

  • Assessed-fee and quantity-discrepancy totals across the report

  • Coaching-level summary with the highest severity present
  • A fixed prevention checklist for the problem types you supplied

Who it is for

Amazon FBA sellers, prep centers, and operations agents reducing repeat inbound defects and charge leakage before a human verifies the live report and any assessed fee.

Delivery: usually a structured result, workbook, or ZIP depending on the tool.

How it stays safe

Friday groups and ranks only the inbound-problem records you supply—problem type, shipment, SKU, coaching level, quantities, and assessed fee. It reads no Seller Central account, inbound-performance report, shipment, or charge; verifies no fee, quantity, coaching level, or classification; and does not open, appeal, or dispute a charge. Friday does not publish listings. Prevention steps are generic drafts, not Amazon policy or a promise a charge is recoverable. A human must map the report fields and verify the current report and any charge before acting.
