Estimating & invoicing software built for HVAC contractors
Quote changeouts, mini-splits and duct jobs in minutes with AI that knows HVAC scopes — then invoice and get paid from the same app. From $19/month for your whole crew. 0% platform fee on payments.
Built around how hvac contractors actually work
Good/better/best sells systems
The 14-SEER budget option, the 16-SEER sweet spot, the heat-pump upgrade — HVAC has always sold in tiers. FieldsHub generates the three-tier proposal automatically so every quote upsells itself.
Summer chaos, winter books
In July nobody has time for paperwork; in January you find the unbilled jobs. Estimates, invoices and payments happen on-site in minutes, so busy season doesn’t leave money behind.
Financing-sized invoices
A $12k system replacement shouldn’t wait on a mailed check. Collect deposits online the day they sign, invoice the balance at startup — card or ACH, 0% platform fee, automatic reminders.
Everything between “can you quote this?” and “paid”
