The short answer
An active team pool is one credit budget shared by owners, administrators, and members. Viewers cannot spend it. Further invitations do not increase the budget. For example, if one person uses 100 credits and another uses 50 from a pool of 5,000, the team has 4,850 left. A Professional pool receives 1,000 credits per month, an Enterprise pool 5,000. The pool must be set up, its period must still be running, and your membership must exist. A plan badge or creating a team alone does not guarantee an active pool. If it is missing, have the setup checked.
