HVAC jobs move fast. Your invoicing should too. Send a professional invoice from your phone before you pull out of the driveway.
HVAC technicians deal with some of the most time-sensitive service calls in the trades — a broken furnace in January or a failed AC unit in July means customers want it fixed and want to pay and move on. The last thing you need is to fumble with paperwork or chase down payment weeks later.
The right invoice app for HVAC techs needs to work fast, handle parts and labor tax correctly, and make it easy for customers to pay on the spot.
Save your standard rates once — "Diagnostic fee — $85", "Labor — $95/hr", "Refrigerant R-410A — $45/lb" — and tap them when building an invoice. Never retype the same numbers twice. Your most common line items are one tap away.
Set your tax rate once in settings. Then on each invoice, toggle which lines are taxable. Parts and refrigerant are taxable. Diagnostic and labor charges usually aren't. FieldPay calculates it correctly every time and shows the customer a clean breakdown.
Finish the job, open FieldPay, build the invoice in 60 seconds, and text it to the customer before you drive away. They get a professional invoice link showing every line item, the total due, and all your payment options. Getting paid while you're still on site is now a real possibility.
Running multiple techs? Add worker seats and your entire team invoices under your business name. You see every invoice on your dashboard in real time. Workers just create invoices — you control the billing.
Set a follow-up threshold and FieldPay alerts you to any unpaid invoices. Resend a professional text or email reminder with one tap — no awkward personal messages from your cell.
💡 HVAC techs who send invoices immediately after the job get paid 2-3 days faster on average than those who bill at end of week.
Jobber and Housecall Pro are popular in HVAC but run $49-$169/month and are loaded with features most small operations don't need — CRM, scheduling, GPS dispatch, customer portals. FieldPay focuses on what actually matters: getting paid. At $24/month it's a fraction of the cost.
ServiceTitan is built for large HVAC companies with 10+ techs. If you're a solo tech or running a small crew, it's overkill and extremely expensive.
