The ENTERPRISE plan enables easy and cost effective sharing of a Floating License in a larger team. The Floating License is managed by the ReqView License Server installed on-premises or in the cloud. The server allows only the purchased number of Floating Clients (instances of the ReqView application) to have a license checked out at the same time.
If a ReqView application instance cannot check out a Floating License from the server, then it only enables features from the FREE plan. You can still open, browse, and print projects.
