When referring to Billing you may hear about active or potential users. Here is an explaination explanation of what each means.
Active users - These are users who have used a licence and make up the current usage. This could be a user who has accessed at least one module from a subscription library or has accessed the LMS or compliance tool.
Potential Users - These are users who have the potential to use a licence for the current subscription. These may be users who have been assigned at least one course from the subscription library but have not started any yet. Or perhaps a user with access to the LMS or compliance tool but has yet to log in and make use of the platform.
