What HVAC technicians keep telling us
The problems we hear on every intro call — and how Glo Invoice fixes them.
Seasonal capacity crunch
You're slammed in July and January. Automation on estimates, invoices, and reminders keeps admin off your plate when it matters most.
Equipment models + serials
Every install needs to log make, model, serial for warranty. Custom fields print on the invoice PDF.
Twice-a-year tune-ups
Recurring invoices bill maintenance contracts on the day they're due — no chasing.
How it works for HVAC technicians
Three steps. Under a minute apiece.
Load calc & quote
Log the home, log the system. Send an estimate with unit specs and warranty terms.
Install & sign off
Attach photos of the new unit, the disconnect, the condensate line. Customer signs on your phone.
Enroll in maintenance
One tap turns the customer into a recurring maintenance account. Twice-a-year invoices bill themselves.
