Free HVAC Invoice Template (PDF)

An HVAC invoice has to hold service calls, maintenance agreements and full installs without turning into a mess. This one keeps equipment, labor and parts on separate lines so the customer can see exactly what they paid for — and so you can job-cost it later.

Common questions

Does this work for both service calls and installs?
Yes. Short service calls use two or three lines; installs use the equipment block plus labor. Same document either way, which is the point — one form your techs never have to think about.
Should I invoice before or after the job?
After. Quote with an estimate, bill with an invoice, and get the invoice out the same day. Every day you wait is a day the customer's memory of the work gets fuzzier.
