If a user has already accepted your invitation for joining a business account and their status is Active, you can invite them to any of your teams. To do so, open the Users section of your business account and locate the user you would like to invite to a team (or teams). Hover your mouse over the green button to the rightmost of it and you will see the “Add user to team” button info. Click this button and you will get a list of the available teams you can add the user to. Mark the appropriate checkboxes and click Add User(s). Note that only business account owners and users who hold Team Management permissions can invite users to teams.
