You can only add team members to a premium or All Access plan. Just pick your plan and add the number of seats you need, you can always change this later.
Once you create a team you can add or remove team members from central admin account.
You can book for yourself and the team together as one person, and the team can also book for themselves wherever and whenever they want.
If you want to have your own office bookable by staff, we can also do this for you as an option.
