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.

Log into your system with:

ssh myusername@mydomain -p 2222

Using cursor keys and Enter key select Administrator controls and type in your password.

Select Add/Remove Apps then akaunting. Enter the subdomain that you which to use, such as accounts.mydomain.net, and optionally a FreeDNS code.

From the Administrator control panel select Passwords and look up the password for mariadb.

Now in a browser navigate to your subdomain. You will need to enter some details for the database. The password should be the mariadb one.

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 official documentation for details.
