Inv24 was first created in 2008 as free online invoicing software for a small European company. It was made free for anyone to use and quickly became popular. Once we started to receive multiple suggestions on how to improve the software, we were motivated to add an additional paid plan and spend extra resources on improvements.

Inv24 is specially designed for small business owners who prefer to do their invoicing themselves. It is very easy to use and does not require technical or accounting knowledge. Inv24 is fully localized for 30+ countries and is used by over 40,000 registered businesses all around the world, mainly from Europe, North America and Australia.

Our top priorities are ease of use, convenience, safety and confidentiality. We focus all our efforts on making invoicing even more convenient. We securely store your data, do not take additional actions with it and do not transfer the data to any third parties. You can be sure that your data is kept in a reliable place and is well protected by strict European legislation.
