Plans & pricing

Priced per tool. Every new account starts with a free Pro trial, no card needed.

After the free trialWithout a plan you keep every calculator and check, and up to 3 saved projects. To print or download a Groundwork report, buy just that one: A$20 for a whole house or site report, A$5 for one calculation. AI questions, emailing reports and sharing need a plan.
Cancel any timePlans renew automatically until you cancel, and your plan runs to the end of the period you've paid for. No lock-in, and your projects stay yours. Subscribing means you agree to our Terms of Use. Prices are in Australian dollars and include GST, and you get a tax invoice (add your ABN at checkout).
Student planNeeds a confirmed university or college email address (.edu, .edu.au, .ac.uk and similar). For study only, so exports are marked as a student licence.
