The location or address of your Company can be changed within your company profile. Click 'Company' in the right menu. Go to the second 'Divisions' tab.

Here you can add multiple locations/division or edit the default address.

Multiple locations allow you to assign different colleagues to different locations and get an overview of who is working where.

Only the company administrator is entitled to change the address. The administrator may also grant you the user-rights to do so.
