Start FreeFrequently Asked Questions
What should an HVAC invoice include?
An HVAC invoice should identify the unit serviced by make, model and serial number, separate parts from labour, show refrigerant quantities where applicable, state any diagnostic or call-out fee, and record whether the work falls under a maintenance agreement or warranty. Those details are what prevent disputes on follow-up visits.
How do I create and send this invoice for free?
Create a free HelloBooks account and build the invoice in the browser — no spreadsheet to download and no formatting to fix. Send it by email or WhatsApp, and HelloBooks tracks whether it was viewed and chases payment for you.
Can I add my own logo and branding?
Yes. Every HelloBooks plan, including the free tier, lets you apply your logo, colours and business details to the invoice, so what the customer receives looks like your business rather than a generic template.
