How to pay

Bank details or pay link, and when payment is due.

Not registered for GST? Change "Tax invoice" to "Invoice" and leave the GST line out. Customer hasn't paid? Here's how to chase an unpaid invoice.

What an invoice should show in Australia

If you're registered for GST, call it a tax invoice. If you're not registered, don't use the words "tax invoice". ato.gov.au
A tax invoice under $1,000 must show that it's a tax invoice, who you are, your ABN, the date, what you sold with the quantity and price, the GST (or "Total price includes GST" when the GST is exactly one-eleventh of the total), and how much of each sale is taxable. ato.gov.au
For sales of $1,000 or more, it must also show the customer's name or ABN. ato.gov.au
If a customer asks for a tax invoice, give it within 28 days, unless the sale is $82.50 or less including GST. ato.gov.au
Also worth adding: a unique invoice number, your contact details, and when and how you want to be paid. business.gov.au

In New Zealand

Since 1 April 2023, New Zealand doesn't require a "tax invoice". You keep and give "taxable supply information" instead. business.govt.nz
Over $200 up to $1,000: your name or trade name and GST number, the date, a description, and either the amount before GST, the GST and the total, or the total with a statement that it includes GST, if everything is at the standard rate. ird.govt.nz
Over $1,000: also the buyer's name and an identifier such as their address, phone, email or NZBN, if the buyer is GST registered. ird.govt.nz
If a GST-registered buyer asks, give it within 28 days for sales over $200. ird.govt.nz
