What you receive

  • Gross, discount, post-discount revenue, fee, and supplied cost arithmetic per row
  • Post-discount contribution per shipment row and per unit
  • Discount cost, affected rows, and affected quantity by promotion ID
  • Negative-margin and supplied contribution-floor exceptions
  • Unexpected promotion stacks against your supplied count threshold

Who it is for

Amazon FBA sellers, agencies, and finance agents auditing normalized promotion discounts actually recorded on shipped items before a human changes any promotion.

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

How it stays safe

Friday calculates only from the redacted shipment references, dates, SKU/ASIN, quantities, gross revenue, promotion IDs and discounts, marketplace fees, unit costs, contribution floor, and stack threshold you supply. It reads no Amazon account or report, verifies no transaction, cost, fee, discount, or promotion state, accepts no buyer data, and does not claim that a promotion caused a sale. Friday changes no promotion, price, listing, shipment, or seller account and does not publish listings.
