The Account Manager can be found under the Account menu from a desktop browser.

Note: If you need access to Account profile or payment information, but do not see this menu option, contact your Account Administrator to obtain access.

The first tab on this page is the account profile information where you can give the account a new name and update contact information.

Contact information only serves the purpose of identifying the primary contact person for the Account, in the event Clinical Studio support needs to reach out. 

Subscriptions can be updated or changed at any time. Read here about accessing subscription and billing information.
