What you receive

  • Reservation fee (reserved cubic feet x per-cubic-foot fee bid) per scenario
  • Projected performance credit capped at the fee, with a credit-capped flag
  • Estimated net reservation cost and break-even attributable-sales level
  • Fully-offset, partially-offset, no-offset, and estimate-missing bands
  • Queue ranked cheapest estimated net cost first, estimate-missing scenarios last

Who it is for

Amazon sellers and agencies comparing Capacity Manager reservation bids with their own sales estimates and credit-rate assumptions before a human places a bid, rather than a capacity forecast.

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

How it stays safe

Friday performs net-cost arithmetic only on the reserved cubic feet, per-cubic-foot reservation-fee bid, performance-credit rate, and attributable-sales estimate you provide. It reads no Amazon account and looks up no Capacity Manager fee or credit rule. It does not predict how many sales the reserved capacity will produce; the sales estimate and credit rate are your own figures, and Amazon's actual credit formula and cap may differ. A net reservation cost is arithmetic, not a recommendation to bid or a claim about what Capacity Manager will award. Friday places no capacity bid, reserves no space, changes no price, listing, or inventory, does not publish listings, and does not modify a seller account. Confirm current Capacity Manager terms, fees, and credit rules before bidding.
