A planning result, not a postage quote

Carrier invoices can depend on service, zone, account terms, packaging and surcharges. This workspace isolates the geometry and published weight rules so you can spot avoidable surprises before opening a carrier checkout.

What the result keeps separate

Actual weight comes from your scale. Dimensional weight comes from package volume and the selected rule. Estimated billable weight is the greater planning value.
