Put the calculator on your site
This page is for brokers. The calculator on dutystack.com.au stays free. You pay to run the same maths on your own website: logo, colours, your domain. Almost nobody needs the software plan. 14-day trial. Cancel anytime. AUD, billed monthly.
Two products, not two jargon lists
On your website is a snippet you paste into WordPress, Carrd, or a landing page. The estimate stays on your URL. That is the $49 plan.
In your software is for a developer. The app sends a price and the concession settings. DutyStack returns duty, cash-to-complete, and an optional PDF. It is not a second calculator. It is a pipe into software you already own. Rate-table changes are emailed to the account. We do not POST into your CRM unless you build that yourself.
