How to Invoice as a Freelancer

Question

Accepted Answer

To invoice as a freelancer in Australia, agree the scope and rate in writing before you start, then send a clear, itemised invoice that includes your ABN and your payment details. Charge GST only if you are registered for it.

Set scope and rate up front. Most invoicing disputes start long before the invoice is sent. Confirm the deliverables, the rate (hourly or per project), the timeline, and what happens if scope changes, all in writing, before any work begins. A short email or simple agreement is enough, and it gives both you and the client a shared reference if questions arise later.

What to put on a freelance invoice. A clean, complete invoice gets paid faster and keeps you compliant. Include the following.

- Your details: your name or trading name, your ABN, and contact information.
- Client details: their business name and, for a tax invoice of 1,000 dollars or more, their identity or ABN.
- Itemised work: each task or deliverable described clearly, billed by the hour or per project, with quantities and rates.
- Totals: a subtotal, any GST, and the final amount payable.
- GST if registered: if your turnover has reached the 75,000-dollar threshold and you are registered, label the document Tax Invoice, show your ABN, and add 10 per cent GST. If you are not registered, send a plain Invoice with no GST.
- Terms and payment details: your due date and how you would like to be paid.
- A unique, sequential invoice number and the issue date.

Quote your ABN to protect your pay. Always show your ABN. Without it, on amounts over 75 dollars (excluding GST), the client may have to withhold 47 per cent of your fee under the ATO no-ABN withholding rule. With it, they can pay you in full.

Use deposits and milestones for larger jobs. For a big project, do not carry all the risk yourself. Ask for a deposit before you begin, then bill against milestones as stages are completed. This steadies your cash flow, confirms the client is committed, and means a single late payment never holds up the whole engagement.

Getting paid faster. A few habits make a real difference to how quickly money lands.

- Invoice promptly, ideally the same day you finish the work, while it is fresh for the client.
- Keep payment terms short and clear, such as 7 or 14 days.
- Offer more than one payment method so paying you is easy.
- Send a friendly reminder shortly before, and just after, the due date.

Keep your records. Hold on to copies of every invoice you issue for at least five years, as the ATO requires. Clear digital copies are fine, and keeping them organised makes tax time and any review straightforward.

A free tool such as InvoiceSonic lets you build a professional, itemised, ABN-ready invoice in minutes, set your terms, and keep a tidy numbered record of everything you send. This is general information only and not tax advice; check your own situation with the ATO or a registered tax agent.
