Owners of Business Profiles can invite users to become owners and managers. Each person can have their own access and they don't share sign-in info. Owners and managers have different levels of access to the profile.

• Only owners can add or remove users.
• Managers can remove themselves from a profile.
• Google Groups can’t be added as managers or owners.
• Only the primary owner can transfer primary ownership.

1. Go to your Business Profile. Learn how to find your profile.
2. Click Menu Business Profile settings Managers.
3. At the top left, click Add .
4. Enter a name or email address.
5. Under "Access," choose Owner or Manager.
6. Click Invite.

Tips:

• Invitees will have the option to accept the invitation and immediately become users. When they accept your invitation, you’ll get a notification email. Users in the account can find the names and email addresses of the owners and managers.
• You can find all active users and people who are invited to become users. To cancel pending invitations, click  in the row.
• If you want to transfer ownership of your profile, you can learn how to transfer ownership of a profile.

• Delete or undelete a profile.
• Remove other owners or managers from a profile.
• Transfer primary ownership to themselves or a third user.

If the new owner or manager deletes their account within the first 7 days, they’re removed from the profile. If they change their mind, they must be added again.
