What the tools do
Handy Nook brings together ten everyday utilities for text, data, conversions, calculations, passwords, images and colour contrast, plus ten parcel and seller calculators. The aim is to help sellers organize basic planning numbers before checking a carrier quote or making a packing decision.
How estimates are produced
The chargeable-weight calculator compares actual weight with a volume-based estimate using the divisor you enter. The carton tool checks six straight rectangular orientations. The profit tool subtracts product cost, a percentage fee, shipping, packaging, and other entered costs from the selling price.
Limits
These are general planning tools. They do not know a carrier's current service rules, surcharges, contract rates, packaging constraints, taxes, or marketplace fee schedules. A grid-fit estimate is not a packing simulation. Check important numbers with the carrier, marketplace, accountant, or other responsible provider.
