What you receive

  • Percentage fee, minimum-applied flag, and recomputed charge for every row
  • Reported-versus-recomputed discrepancy and possible overcharge exposure
  • Mismatch-first review queue with your own high-exposure threshold
  • Single-currency category summaries with mismatch and minimum-applied counts
  • Transparent rounding, tolerance, and grouping notes for human review

Who it is for

Amazon sellers, agencies, and finance teams checking a seller-supplied referral-fee export for miscategorized SKUs or wrong-rate charges before a human reviews the source transactions.

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

How it stays safe

Friday performs arithmetic only on the snapshot date, SKU and ASIN references, category label, currency, unit price, referral-fee percentage, per-unit minimum fee, units, and amount charged you provide. It reads no Amazon account, report, fee schedule, or category assignment and verifies no field. A discrepancy is between your supplied fields for human review—not a finding that a charge is wrong or that a credit, reimbursement, waiver, or dispute is available. Friday opens no case, files no dispute, changes no price, listing, or category, does not publish listings, and does not modify a seller account.
