Plans and prices
Calculating a cycle is free. The paid plans are for carrying a project through the whole calculation chain and issuing the reports that go to your client. Prices are per seat, exclude tax, and are fixed in each currency rather than converted.
US dollars, excluding GST, VAT and sales tax. Stripe adds the tax that applies at checkout, from your billing address.

Professional trial
A new account gets Professional features for 14 days on its first project, starting when that project is saved: every cycle type, the whole chain and issued reports. No card needed. When it ends, the account carries on as Free and nothing is deleted.
Education
Free Professional for students and teaching staff at universities, TAFEs and other tertiary institutions, aged 18 or over. Apply with the email address your institution gave you; Sentoro checks each application by hand. Reports made under Education are marked “not for commercial use”.
Kelvin Founding 25
Professional at US$490 a seat a year, billed annually and fixed for two years, for the seats on your first order. Year three is US$740 a seat, then the standard Professional price. Seats added later are at the standard price, and we give 60 days’ notice before each change.
For the first 25 firms, who take part in a recorded review of a worked example with us. We may ask whether we can name you as a customer; saying no doesn’t affect your price. Closes 31 January 2027.
Sentoro Connected
25% off Team seats for a firm whose Deployr organisation is on Commercial or Projects with the HVAC&R pack. It applies at checkout once Deployr confirms the plan through the Deployr link, which Deployr can’t do yet.
Enterprise
For 10 or more seats: single sign-on, invoice billing and custom reference libraries on top of Team. Quoted, starting at 20% off Team. Email us with your seat count and what you need.
Tax is added at checkout
Stripe works out Australian GST, UK or EU VAT, or US sales tax from your billing address, and business customers can enter a tax ID. Invoices and receipts come from Stripe on behalf of Sentoro Technologies Pty Ltd.
