Price the cubic feet needed to get back under your supplied storage limit.
Included in the $9.00 Shelf Kit
Amazon FBA sellers, agencies, and agents comparing supplied storage-overage reduction options before a human changes inventory or capacity.
Delivery: usually a structured result, workbook, or ZIP depending on the tool.
Friday performs arithmetic only on the usage, limit, overage, charge rate, fee, unit count, cubic reduction, and costs you supply. It reads no Amazon account, capacity limit, rate card, Inventory Storage Overage Fees report, inventory position, or forecast. A mismatch is not a finding that Amazon measured or charged you incorrectly, and a break-even result assumes supplied reductions and costs persist for the whole horizon. Friday creates no removal, predicts no demand, changes no price, capacity, or inventory, and does not publish listings or modify a seller account.
