Hi info3381!

Subaccounts allow you to bring in multiple users to view or help manage your ADYOUNEED account! Each Subaccount allows one client or team member to access an ad account. They can either be allowed to edit and create ads for this account, something you would give to a team member, or they can be set to read-only where they can view the data and results, but cannot edit your campaigns, used for clients who want to monitor your progress.

In summary, you should aim to have enough subaccounts for both your team members and clients!

Let me know if you have any other questions!
