Pay once · No Friday subscription
Catch dim-weight and size-tier surprises before you price a product.
Included in the $9.00 Shelf Kit
Sellers, agencies, and ops agents pressure-testing dimensions against a carrier or marketplace size-tier table before a human sets price or packaging.
Delivery: usually a structured result, workbook, or ZIP depending on the tool.
Friday performs arithmetic only on the dimensions, weights, divisor, and tier table you supply. It fetches no live carrier or marketplace rate, calculates no fee, surcharge, or delivery date, and does not verify your divisor or bounds against a current schedule. Billable weight is the greater of supplied actual and computed dimensional weight, not a shipping quote. Friday reads no account, shipment, or order; does not publish listings; and does not rate-shop, book, or label anything.
