Licenses and billing in a group
Where the pool is visible, what a child can and cannot do, and how to find out who is holding the licenses.
Where to look
Both see it under Settings > Billing & subscription. The parent's page shows how many screen licenses the plan includes and how many are used, and Workspaces on this plan opens a table of every workspace sharing it. A child's page says the parent pays for it, and shows how many of the shared licenses the child itself uses.
In the parent, the used count includes screens in every child, not only its own. A parent showing more licenses used than it has screens is normal and is the point of the arrangement.
See The license pool for what each counter means.
What a child can do
See the pool, and connect screens against it while licenses are available.
What a child cannot do
Change the subscription, the plan, the screen count, or the payment method. Its billing page says the parent pays for this workspace, there is no Manage subscription, and the Plans page says plans can only be switched from the parent.
To change anything, switch to the parent workspace.
Running out
The pool is shared and first come, first served. There is no per-child quota and no reservation, so one region rolling out fifty screens can leave another unable to connect one.
Two consequences worth planning around. Tell the parent before a large rollout, not during it. And when the pool is full, the fix is either buying more licenses at the parent or disabling screens somewhere, since nothing can be reallocated.
Finding out who is holding them
In the parent, the Workspaces on this plan table sorts by licenses used, and its export button gives you the table as a CSV.
That export is the useful artifact when asking teams to give some back. Sorted by licenses used, it names the two workspaces holding most of them in about ten seconds, which is a better conversation than an all-round request.
