Frequently asked questions

What must a tax invoice include?

Rules vary by country. In Australia, a tax invoice for GST must show the words “Tax invoice”, your ABN, the date, a description of what was sold and the GST amount (and the buyer’s details for sales over $1,000). Check your tax authority’s requirements.

How do I number invoices?

Use a unique, sequential number for every invoice, such as INV-2026-001, INV-2026-002. Never reuse a number.
