Yes, we do. Our group license allows an administrator to manage multiple licenses from a single account. Each user in the group gets a separate user account / login.
The admin can pay using a single card for all the child accounts, and also has the ability to revoke licenses and re-assign them to others (when people join or leave your organization). The cost of the group license is N * 20 USD per year, where N is the number of people in the group. So, for a group of 5, that would be 100 USD per year.
