Who it is for

Amazon Subscribe & Save sellers, agencies, and agents joining seller-supplied Replenishment metrics with current inventory and unit economics before a human replenishment decision.

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

How it stays safe

Friday calculates only from the performance metrics, 30/60/90-day forecasts, inventory, lead time, safety stock, price, discount, fees, costs, and thresholds you supply. It reads no Amazon account or Replenishment API response and verifies no forecast, inbound arrival, retention, lost revenue, program status, or discount funding. Interpolation is not a Friday demand forecast. Friday places no order, changes no Subscribe & Save offer or discount, does not publish listings, and modifies no seller account. Review fresh source metrics before acting.
