How to fill in your HVAC invoice

Three steps from completing your first job to getting paid — without the paperwork headache.

  1. Fill in your business and client details

    Add your company name, address, and phone. Then add your customer's details and a unique invoice number.

  2. List your labor and parts separately

    Use one line per service or part. Include description, quantity, unit price, and the applicable sales tax rate.

  3. Set a due date and add payment instructions

    Enter your calculated totals, choose a due date, and add your payment details in the Additional Notes field.

What to include on an HVAC invoice

A complete, accurate HVAC invoice protects you and your customer — and gets you paid faster. Here's what to include every time, whether you're billing for a residential repair or a commercial installation.

Your HVAC business name, address, and phone

So customers know exactly who to contact and who to pay.

Client name and address

Include company name for commercial jobs — essential for their accounts payable team.

Invoice number and invoice date

A unique invoice number supports good record-keeping and helps distinguish one invoice from another.

A clear due date — 7–14 days pays off

Ensure your invoice includes a clear due date, so customers know how long they have to pay.

Get paid faster on every HVAC job

Xero helps you get invoices out on time, maintain your due dates, and follow up on unpaid invoices for you. For HVAC businesses with seasonal cash flow pressures and upfront parts costs, that wait hurts. Here's how to close the gap.

Send your invoice the same day

The sooner you send it, the sooner the clock starts. Invoice while the job is fresh — don't let it pile up.

Shorten your payment terms

Try 7 or 14 days instead of 30. Ensure your invoices always specify a due date, so customers know how long they have to pay.

Always ask for a PO number on commercial jobs

Without a PO number, your invoice can be rejected or lost in the system — and you won't know until you chase.

Include clear payment instructions

Use the Additional Notes field to tell customers exactly how to pay: bank details, accepted methods, and any late payment terms.

Follow up before the due date

A polite reminder a few days before the due date keeps your invoice top of mind without being pushy.
