Having your osFinancials (administration(s)) running on our servers gives you the flexibility to work on your administration at the office during office time, and checking things in the evening at home.
It's also possable to give your accountant or co-workers access* to your administration.
You can also use Open Office.

* It's only possable to access your administration with one session at the time.
If you want multi user access, than you can buy "addition workstations".
This is a monthly fee.
