Tax invoice vs a casual total
A tax invoice is the document a GST-registered buyer often needs to claim credits. A one-line email (“$2,200 thanks”) is not enough for their records even if they pay it.
Keep the commercial spine aligned with the invoice checklist. GST-specific extras (ABN, Tax Invoice wording, GST amount) sit on top of that spine.
Fields that usually appear
Typical fields: supplier identity and ABN, the words Tax Invoice when required, invoice date, unique number, customer details, description of supplies, GST amount, and total payable.
- AUD unless you truly quoted another currency
- GST shown as its own amount, not only buried in a tax-inclusive total
- No GST line if you are not registered
Rates and registration
Not registered? Start from a no-GST layout and leave Taxes empty. Registered? Match the rate to the supply — many generators start at 10%, but that is not universal for every line.
Do not copy a New Zealand 15% layout onto an Australian job. Use the NZ GST guide only when you bill NZ clients in NZD.
Using the Australian generator
Open the Australian GST generator or the Australia hub. Add your ABN under From, itemize taxable supplies, set GST under Taxes, download PDF.
Propose work first with an estimate from /au, then convert when the job is done — estimate vs invoice. Editor basics: how to create an invoice.
