Say what you did
Type the job the way you'd say it, for example "replaced a dual run cap, added 2 lbs of refrigerant and cleared the drain line". Handbill turns it into invoice lines priced with your own rates. You check them and send.
An invoice that fits the job
With Pro, pick the Work order style: boxed fields, a gridded table and a line for the customer to sign, like the work orders HVAC techs already fill out. Add your logo, cropped to a circle if you like, and pick from ten colors. Seven other styles are there too. See every style.

Get paid without fees
Clients pay you directly by cash, check, bank transfer, Zelle, Venmo or your own card reader. Handbill records the payment and never takes a cut. Overdue invoices are flagged so you know who to chase.
Tips for HVAC techs
- Write the refrigerant type and pounds added on the line; the next visit and any warranty claim will need it.
- Say on the estimate whether the diagnostic fee is credited toward the repair, so nobody argues about it later.
- Put the model and serial number in the job notes; you will want them on the next call.
