The Freedombone system isn't primarily aimed at companies or institutions, but if you're a one person company or freelancer then having the ability to run your own accounting system and keep the data private and also backed up is useful. Akaunting provides a nice web based system for small business accounts, and is also quite usable within a mobile web browser.
After that you'll need to enter a company name and an email address. You can make the administrator password anything you prefer, and a suggestion can be found within the *Passwords* section of the *Administrator control panel* under *akaunting*.
From then on the system should be usable. Accounts software can often be quite complex, and so you'll probably want to refer to the [[https://akaunting.com/docs][official documentation]] for details.
