Terms of use

Plain Invoice is free to use for any invoice you make. It is provided as is, without any warranty. The code is open source under the MIT licence.

You are responsible for what your invoices say, including your ABN, GST and payment details. The explanations on this site are general information, not tax or legal advice. Check the ATO or a tax agent for your situation.

Your invoices and details stay on your device. Keep your own copies: if you clear your browser's data, anything saved here is gone.
