With manual license management, you choose and pay for a fixed number of licenses, which limits the number of users in your organization. - If the limit is reached, unlike [automatic license management](#how-does-automatic-license-management-work), new users cannot join and existing users cannot be reactivated until licenses are manually added (or freed up by [deactivating existing users](/help/deactivate-or-reactivate-a-user)). - When you add a license for the current billing period, you will be charged only for the remaining part of the billing period. - If you have an annual billing period, each month, you will see a single charge for all licenses added the previous month. If you have a monthly billing period, the charge for licenses added during the previous month will be combined with your monthly renewal charge.
