Australian Invoice Requirements — What You Need to Know

Australian tax law sets specific requirements for invoices, particularly when GST is involved. If you are registered for GST and your invoice exceeds $75, it must be a "Tax Invoice" — a specific document format required by the ATO. This generator creates ATO-compliant tax invoices that satisfy all mandatory fields.

For tradies — plumbers, electricians, builders, and others — invoicing correctly is critical to getting paid on time and maintaining clean records for BAS lodgement. A proper tax invoice allows your clients to claim GST credits, making them more likely to pay promptly and without disputes.

Sole traders and small business owners often lose money through poor invoicing — either by forgetting to include GST, missing mandatory fields, or using informal payment requests that clients can dispute. This free tool removes those risks by generating a complete, professional PDF that you can send directly to your client or print for your records.

Business details are saved to your browser's local storage, so returning users don't need to re-enter their details. Invoice numbers auto-increment to help you stay organised. GST calculation is automatic — toggle it on or off depending on whether your business is GST-registered.
