How to Create an Invoice in Australia

Creating an invoice in Australia follows ATO guidelines and the GST rules in the A New Tax System (Goods and Services Tax) Act 1999. If you're registered for GST, your invoice must be a "tax invoice" — if not, a standard invoice is fine but you still must include your ABN where one is required.

To create a compliant Australian invoice:

Open a free invoice generator like InvoiceSonic or a clean template
Enter your business name, ABN, address, and contact details
Add the client's name and address
Generate a unique sequential invoice number and use today's date
List each item or service with quantity, unit price, and line total in AUD
If you're GST registered, label the document "Tax Invoice" and show GST as a separate line or state "Total includes GST"
Show subtotal, GST, and total amount payable
Add payment terms, due date, and bank or PayID details
Save as PDF and send to the client by email

Keep a copy for five years to meet ATO record-keeping requirements. InvoiceSonic is built for Australian businesses and handles ABN, GST, and tax invoice formatting automatically.
