How to create an invoice online
Three steps from blank page to a professional PDF.
Step 1
Add your business and client details
Fill in who's billing and who's paying — that's the minimum a legally solid invoice needs.
- Your business name & ABN — Shown on the invoice header so clients know exactly who to pay.
- Bill-to client details — Name is enough to start — add billing and service addresses for bigger jobs.
- Invoice number & dates — Auto-generated number, issue date and due date — editable if you have your own system.
Step 2
Add line items — watch the invoice build itself
Every line you type appears instantly in a live preview of the finished invoice.
- Itemised lines with qty × price — Clear descriptions get approved (and paid) faster than lump sums.
- Totals calculated automatically — Subtotal, GST/tax and total update as you type — no broken spreadsheet formulas.
Step 3
Download, send, and get paid
Grab a clean PDF or email it directly. Your payment details go right on the invoice.
- HVAC + a free bank option — Offer both — clients who pay by bank cost you 0% in fees.
- Professional PDF, no watermark — A real record for your accountant, tax time, and any dispute.
- Payment terms on every invoice — Due dates and terms set the expectation — and speed up payment.

Why HVAC alone makes getting paid harder
A payment request is not an invoice—and clients can tell the difference.
Word and Excel invoices are fiddly
Reformatting a hvac invoice every time, fixing broken totals, and exporting to PDF eats time you'd rather spend working.
They look inconsistent
Mismatched templates and manual maths make a bill look less professional — and slower to get approved and paid.
No easy way to get paid
A static file doesn't tell the client how to pay you, so payment drags.

Start free — create invoiceA practical guide to HVAC billing
Use the template as a starting layout, then replace its example information with the actual agreed work. The details below help you decide what to enter and what to check before sending.
Agree what this invoice covers
Separate maintenance, fault diagnosis, repair and new installation. Identify the equipment serviced and explain what a maintenance package includes. Obtain approval for replacement parts or additional repair work discovered during the visit.
Give the payer enough context
Include the property address, equipment reference, service date and work-order number. Check the legal billing name and delivery contact against the accepted work. Keep the accepted maintenance or installation scope, approved repairs and completion record available to resolve questions. An invoice records the charge; it does not replace the underlying approval or supporting documents.
Worked HVAC invoice example
Two units receive the agreed service, with one approved component billed separately. Identify the actual equipment and scope; these prices are not installation estimates or local market rates.
| Description | Quantity | Rate | Amount |
|---|---|---|---|
| Scheduled unit maintenance | 2 | 95.00 | 190.00 |
| Approved replacement component | 1 | 120.00 | 120.00 |
| Example subtotal | 310.00 | ||
Avoid this billing mistake
Charging a separate labour line when installation labour is already included in a supplied-and-fitted part can lead to a dispute. Match the invoice to the quoted supply basis.
Follow up on the right record
For managed buildings, use the work order and payer’s equipment reference. Keep warranty, maintenance schedules and technical compliance documentation separate from the payment record.
Before you send
- Match the line items and quantities to the accepted scope and approved changes.
- Check the invoice number, issue date, explicit due date and the property address, equipment reference, service date and work-order number.
- Apply only the tax treatment relevant to your business and location; check current local requirements if unsure.
- Keep earlier billing separate from actual payments. Verify the outstanding amount and payment instructions.
The free browser tool prepares the document. Saving customers, sending tracked invoices and managing reminders require an account and are subject to plan limits. Payment status needs accurate payment records; an invoice view alone does not confirm payment.
