What you receive

  • Cent-rounded service and payment-processing fee recomputes
  • Independent recorded-fee and net-proceeds comparisons
  • Fee-and-net, fee-only, and net-only review bands
  • Directional exposure totals that never cancel each other
  • Service versus payment-processing component summaries

Who it is for

Buy with Prime merchants and bookkeepers checking seller-redacted DTC order rows against the fee terms shown in their own source records before a human reviews any payout question.

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

How it stays safe

Friday performs arithmetic only on seller-supplied DTC order dates, references, listing and SKU aliases, currency, proceeds-before-fees basis, fee bases, percentages, flat amounts, recorded deductions, and recorded net proceeds. It reads no Amazon or Buy with Prime account, fulfillment report, payout ledger, order, listing, or fee schedule and verifies no source field. Amazon alone determines the applicable service-fee structure, payment-processing treatment, bases, taxes, shipping deductions, refunds, and actual net proceeds. A difference is a bookkeeping review lead, not proof of a wrong charge, missing payout, refund, credit, or amount owed. Friday opens no case, files no dispute, requests no credit, moves no money, changes no order, listing, price, payout, or seller account, and does not publish listings.
