For new teams: Adding a member to a team will use one seat per team member. The inventory is decremented when the invitation to the team is sent.
For adding to existing teams: To add new members to an existing team, only the new team members will need to use inventory, and all members will receive updated team reports when the team type is calculated. The inventory is decremented when the invitation to the added team member is sent.
For deleting from existing teams: Deleting a not-started team member will return their seat to your inventory. Deleting in-progress or completed team members will not change your inventory, and the team type will be recalculated, if needed, at no additional cost.
