HVAC contractor invoice FAQ
Do I charge sales tax on HVAC work?
Most US states tax parts/materials but exempt labor. Use Glo Invoice's per-line tax toggle so each HVAC line item is taxed correctly. Check your state — a few (HI, NM, SD, WV) tax services too.
How much refrigerant do I bill?
Type + lbs + per-lb price as separate columns. Customer sees the math.
Warranty work — bill or not?
Bill diagnostic + non-warranty parts. Warranty parts at $0 with claim #.
