 Code Review is billed as a monthly subscription. At the end of each billing period, your organization is charged for the number of seats that were active during that period.

 When seats are assigned automatically, the user whom the seat is assigned to will initially have an **Unassigned** role.
 You can change the role to Viewer, Member, Admin, or Owner.
