HVAC Invoice Generator FAQ
Is this invoice generator really free?
Yes. You can create, preview, print, and download an invoice without an account, email gate, or watermark.
Where is my invoice data stored?
Your draft is saved in this browser so you can return to it. ShiftFlow does not receive the invoice details you enter.
Can I add tax, a discount, and a deposit?
Yes. The generator applies discounts before tax, records any amount already paid, and shows the remaining balance.
How should an HVAC invoice identify the equipment?
Add the system type, model, or serial number when it helps connect the diagnostic work, parts, refrigerant, and warranty to the exact equipment serviced.
Should the diagnostic fee and repair labor be separate?
Separate them when the customer was quoted a service-call or diagnostic charge before repair work began. This makes the visit fee, labor, parts, and refrigerant easier to verify.
