How to create an invoice online
Set up once, then every invoice after the first takes about a minute.
Create your free account
An email address and a password. No card, no trial clock.
Enter your business details
Business name, ABN, address, logo, payment terms and bank details. Saved and reused from here on.
Add the customer and the work
Choose a saved customer or add a new one, then itemise what you supplied with quantities and prices.
…then finish it
Apply GST — or do not
If your account is set to GST registered, 10% GST is calculated and shown separately. If not, GST is left off and the document is labelled an invoice rather than a tax invoice.
Send it or download it
Email it straight from InvoiceGen with the PDF attached, or download the PDF and send it yourself. A copy is kept against the customer either way.
What you need in front of you before you start
None of this is difficult to find, but having it to hand makes the first invoice faster.
| What you need | Why |
|---|---|
| Your ABN | A tax invoice must show the seller's Australian Business Number. Without one on the document, a business customer may have to withhold 47% of the payment. |
| Your GST registration status | This determines whether you issue a tax invoice showing GST, or a plain invoice with none. Registration is required once turnover reaches $75,000. |
| The customer's details | Their name at minimum. For invoices of $1,000 or more you also need their identity or ABN. |
| What you supplied | A brief description of each item or service, with quantity where it applies and the price. |
| How you want to be paid | Bank details or payment instructions, plus your terms — for example, payment within 14 days. |
A note on the $82.50 rule
If a customer asks for a tax invoice, you must provide one within 28 days — unless the sale is $82.50 including GST or less. In practice it is simpler to issue one for everything, which is what InvoiceGen does by default.
Creating invoices online versus the alternatives
Most Australian small businesses start with a Word or Excel template, because it is free and it is already on the computer. It works. It also quietly creates work: you copy last month's file, you change the number, you change the date, you hope you changed both, and you save it somewhere you will be able to find in three years when the ATO would like to see it.
Creating the invoice online moves three of those jobs off your desk. The numbering is sequential without you tracking it. The arithmetic cannot be overwritten. And the record lives in an account rather than in a folder on one laptop, which matters given business records need to be kept for at least five years.
Does an online invoice still count as a proper invoice?
Yes. There is no requirement for an invoice to be printed or posted. A PDF emailed to your customer is a valid tax invoice as long as it carries the required information. Electronic records are explicitly acceptable for the ATO's record-keeping rules, provided they are complete and you can produce them if asked.

Frequently asked questions
How do I create an invoice online for free?
Create a free InvoiceGen account, enter your business name and ABN once, then choose New invoice. Add the customer, add the line items with quantities and prices, apply GST if you are registered, and click Send or Download PDF. There is no cost and no card required.
Do I need to download any software?
No. Everything runs in your web browser. You can create an invoice on a laptop, tablet or phone, and pick it up on another device because it is stored in your account rather than on one machine.
Can I create an invoice online without an ABN?
You can raise a document, but if you are carrying on a business in Australia you should have an ABN, and a tax invoice must show it. If you supply a business customer without quoting an ABN, they may be required to withhold 47% of the payment. Applying for an ABN is free through the Australian Business Register.
How quickly can the customer receive it?
Immediately. Clicking Send emails the invoice to the address on the customer record, with the PDF attached, so it can arrive before you have packed up.
Is my invoice data secure?
Your invoices are stored in your own account behind a password, served over an encrypted HTTPS connection, and are not shared with other users. Keeping them in an account rather than on a single laptop also means you still have them if the device is lost.
