Factunube is a very powerful online invoicing software for small and medium-sized businesses based on a web browser.
It is online: it can be used from any computer with internet access; and it is web-based : it works on an internet browser, without installing anything on your computer.
It is a fairly complete billing program, and it is improving every day. It meets the needs of both freelancers and companies. And it is also multi-user and multi-company , which means that several people can work at the same time, from anywhere. And if you have several companies, they can also be managed from the same program.
