Let’s get started!

When should you send an HVAC invoice?

You should send an invoice immediately after the service is complete (unless there is a special maintenance agreement or contract that requires a different invoicing strategy).

For example, email them the invoice right away once you’ve completed the service. If you’re able to invoice on the spot you’re able to collect payment on the spot with an online payments option which keeps your cash flow healthy.

The longer you wait to send the invoice, the longer it’ll take to get paid. And similarly, the easier you make it to get paid, the longer they’ll take to pay you.

Finally, before you send off the invoice, always make sure that you’re sending your client an updated version. If you made changes to the original quote because you had to order specific HVAC parts once you started the job, then that should be included in the most recent invoice.

If you have to go straight to another job, hand-writing an invoice will take too much time and make you look unprofessional.

Instead, use HVAC invoicing software to create invoices in seconds, text or email them straight to your customers, and collect payment on the spot or online.

When should your client pay their invoice?

Standard HVAC invoice payment is within two weeks of the service date. However, you can test payment deadlines that range between fifteen, ten, five, and two days to see what works best for your business’ cash flow.

Since heating and cooling services can be quite expensive, some business owners prefer to accept a deposit beforehand, and final payment the day of the service.

Pro Tip: You can offer financing to your customers — this makes expensive services more affordable, plus it helps you look more professional and stand out from the competition.

Remember: There’s no right way to structure invoice payments — it has to work for your HVAC business.
