What you receive

  • Exact longest, median, shortest, and comparison-weight reduction needed per SKU
  • Largest required reduction as a percent of the current measurement
  • Separate already-inside-bounds, shave-needed, no-savings, and smallest-tier states
  • Per-unit fee savings from your supplied current and next-smaller fees
  • Conditional annual fee savings from your supplied unit projection

Who it is for

Amazon FBA sellers, packaging teams, and agencies screening a batch of SKUs for near-boundary packaging opportunities before a human validates protection, measurements, current tier rules, and fees.

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

How it stays safe

Friday performs scenario arithmetic only on the ordered package measurements, comparison weights, next-smaller tier boundaries, per-unit fulfillment fees, and annual-unit projections you supply. It reads no Amazon account, Fee Preview, catalog record, or live rate table and infers no dimensional-weight, rounding, category, dangerous-goods, apparel, peak, oversize, or other omitted rule. Meeting four supplied bounds is not an Amazon classification or eligibility finding, and a required shave is not packaging or product-safety advice. Modeled savings are conditional, not guaranteed or recoverable. Friday requests no remeasurement, files no case or dispute, changes no package, price, listing, inventory, or account, and does not publish listings. Confirm protection and current Amazon rules before acting.
