How do I specify whether an administrator has corporate-level or account-level access?

During the process of setting up a new Corporate Administrator, you will be prompted to specify the new user's access-type:

Corporate-level access -

The user will be able to view and manage the corporate account, plus all associated Operating Accounts.

To set up, simply select the 'Corporate Access' option.

Account-level access -

The user will only have access to view and manage specific Operating accounts.

Select 'Operating Account Level' and select one or more Operating Accounts from the menu.
