Any user can be assigned the role of Administrator. The Administrator role has full permissions in BuzzStream for all aspects of the application, with the exception of subscription management.
There is only one Account owner for your BuzzStream account. The Account Owner is the only person who has access to your billing information and your subcription information. This individual also has all the permissions of an administrator.
Only an Account Owner can:
Upgrade or downgrade your subscription
Update the credit card on file for the account
Access all past invoices
RE-assign the account ownership to another user
Cancel the account
