Four tools that hand work to each other
Most invoicing tools stop at the invoice. InvoiceGen follows the job from the first enquiry to the paid invoice, so nothing gets retyped along the way.

Add your business details once
Your name, ABN, address and logo are saved to your account and drop onto every invoice and quote from then on.
Build the invoice
Pull line items from your saved product list or type new ones. GST is calculated as you go, or left off entirely if you are not registered.
Send it or download it
Email the invoice from InvoiceGen with one click, or download a clean PDF to send yourself. Every invoice stays in your account.
An invoice that will not be sent back
A tax invoice that is missing a field is a tax invoice your customer's bookkeeper can refuse — and a GST credit they cannot claim. InvoiceGen's templates are laid out around the ATO's requirements so the document is right the first time.
You do not have to remember which fields apply at which value. Enter the sale and the template does the rest.
-
The words that make it a tax invoice The document is clearly marked so there is no ambiguity about what it is.
-
Your identity and ABN, every time Saved once in your settings and applied to every document you issue.
-
GST shown correctly Displayed as a separate amount, with the taxable status of each line made clear.
-
The buyer's details on larger sales For invoices of $1,000 or more, the buyer's identity or ABN is captured too.

Frequently asked questions
Is InvoiceGen really free?
Yes. InvoiceGen is free to use with no time limit and no card required. You can create unlimited invoices, quotes, orders and customer records without paying anything. There is no trial that expires and no feature that is held back behind a paywall.
Do InvoiceGen's invoices meet ATO requirements?
Yes. The templates include every field the ATO requires on a valid tax invoice: the words 'Tax invoice', your business identity and ABN, the date issued, a description of what was sold with quantity and price, the GST amount, and the extent to which each line is a taxable sale. For invoices of $1,000 or more the buyer's identity or ABN is included as well.
What if I am not registered for GST?
Switch GST off in your settings. InvoiceGen then produces a plain invoice rather than a tax invoice, removes the GST column, and drops the words 'Tax invoice' from the document — which is what the ATO expects if you are not registered. You must register for GST once your turnover reaches $75,000 ($150,000 for non-profits).
How do I send an invoice to a customer?
Once the invoice is built, click Send and it goes from InvoiceGen straight to your customer's email address. You can also download it as a PDF to attach yourself, print it, or keep it for your records.
Can I turn a quote into an invoice?
Yes, in one click. Leads become quotes, quotes become orders, and orders become invoices, each carrying the line items forward so you never retype anything. You can also convert directly from a quote to an invoice and skip the order stage.
Do I need to install anything?
No. InvoiceGen runs in your web browser on a laptop, tablet or phone. Your invoices are stored in your account, so you can start one on site and finish it back at the office.
