Is this invoice generator really free?

Yes — no sign-up, no watermark, no limits. The invoice is generated entirely in your browser and downloaded as a PDF; your business and client details are never uploaded to a server.

What's the difference between an invoice and a tax invoice?

A tax invoice is an invoice that meets the ATO's GST requirements — it says 'Tax Invoice', shows your ABN and the GST amount, and may only be issued by a GST-registered business. If you're not registered for GST, you issue a plain invoice with no GST.

Do I need an ABN to invoice someone?

Effectively yes. Without an ABN on your invoice, business customers are generally required to withhold 47% of the payment under the no-ABN withholding rules. Applying for an ABN is free at abr.gov.au.

Do I charge GST on my invoices?

Only if you're registered for GST. Registration is mandatory once your turnover reaches $75,000 a year, and optional below that. If registered, add 10% to taxable sales and report it on your BAS; if not, charge no GST at all.

What must be on an invoice for more than $1,000?

A tax invoice for a sale of $1,000 or more must additionally show the buyer's identity or ABN, on top of the standard requirements (seller identity, ABN, date, description, GST). This generator warns you when the total crosses that threshold.

How long should I keep invoices?

Five years, per ATO record-keeping rules. Keep the PDF you send and note the payment date — invoices are the primary evidence of your business income.

What makes a tax invoice valid in Australia?

The ATO requires seven things on a tax invoice: the words "Tax Invoice", your identity, your ABN, the date, a description of the items (with quantity and price), the GST amount (or a statement that the total includes GST), and the extent to which each sale is taxable. For sales of $1,000 or more it must also show the buyer's identity or ABN — this generator flags that automatically. If you're not registered for GST you must not issue a "Tax Invoice" or charge GST; your document is simply an "Invoice", which is how this tool titles it.

Invoice vs quote

A quote is an offer — it states what you'll charge and how long the price stands (the "valid until" date), and creates no payment obligation. An invoice is a demand for payment for work delivered. Keep the numbering separate (this tool prefixes QTE- and INV-) and convert a quote to an invoice by switching the toggle once the work is done — the line items carry across.

Official sources

GST treatment and required fields follow the ATO's tax-invoice rules. This is a document generator, not accounting software — keep copies for your records (5 years).

How to Use This Calculator

2Choose Invoice or Quote, set the number and dates.
3Add line items with GST-exclusive prices; mark any GST-free lines.
4Check the total, then download the PDF and email it to your client.

Invoicing as a sole trader

Every invoice needs your ABN — without one, businesses paying you may be required to withhold 47% of the payment (the 'no ABN withholding' rule).

If you're registered for GST you add 10% to taxable sales and issue tax invoices; you then report and remit the GST on your BAS. If you're not registered (under $75,000 turnover) you charge no GST and issue plain invoices.

Keep copies of every invoice for five years — they're the evidence base for your income when you lodge your tax return.

Getting paid faster

Short, explicit terms: State the due date rather than '30 days EOM' — 7 or 14-day terms are normal for sole traders.
Bank details on the invoice: BSB and account number on the document removes a whole email round-trip.
Sequential numbering: Unbroken invoice numbers make your bookkeeping and any ATO review straightforward.
Invoice immediately: Invoices sent on completion day are paid measurably faster than end-of-month batches.

Common mistakes to avoid

•Charging GST when you're not registered — you'd have to refund it or remit it; either way it's a problem.
•Writing 'Tax Invoice' on a document with no GST — unregistered sellers must use 'Invoice'.
•Forgetting the buyer's details on invoices of $1,000+ — the client's bookkeeper will bounce it back.
•Quoting GST-inclusive but invoicing GST-exclusive — pick one basis and label it clearly.
