ContainerMath vs CargoWiz
A one-time Windows licence vs a browser workspace with compliance checks built in.
CargoWiz is a long-running Windows desktop load planner from SoftTruck. You enter products, pick containers or trailers, and it fills them, with a drag-and-drop editor to adjust the result, a Container Advisor that picks equipment by shipping cost, and Excel import for bulk product lists. It is sold per user as a one-time purchase or an annual subscription, with a 30-day full-featured trial.
Disclosure: this page is published by ContainerMath. We aim to represent CargoWiz fairly, cite public sources, and say plainly when it's the better pick. Pricing as of September 2026 — verify on the vendor's site before buying.

Where CargoWiz wins
Where ContainerMath wins
If you want to buy once and never see a renewal, run on Windows anyway, and your loads are simple boxes where weight legality is not a concern, CargoWiz's one-time licence is a fair deal and its editor is pleasant to use. Once axle loads, hazmat or a team that shares plans enter the picture, the browser workspace earns its subscription.
