How to Do an Invoice in Australia

Doing an invoice in Australia means producing a document that meets ATO requirements and getting it to the client quickly. The process is straightforward when you use the right template or generator — and faster when you're not registered for GST, since you don't need to label it a "Tax Invoice".

Step by step: 1. Pick an invoice tool — InvoiceSonic is free and designed for Australian businesses 2. Add your business name, ABN, address, and contact details 3. Use a unique sequential invoice number and today's date 4. Enter the client's name and billing address 5. Itemise each product or service with description, quantity, and rate 6. Calculate subtotal, GST (if you're registered), and total 7. Set the payment due date — 7, 14, or 30 days is standard 8. Add bank details, BPAY, or PayID for payment 9. Download as PDF and email it to the client 10. Save a copy and follow up before the due date

Keep all invoices for at least five years to meet ATO record-keeping rules. Most businesses use accounting software or a generator rather than Word or Excel, because the formatting and numbering is handled automatically.
