Microsoft is starting to roll out a new volume-licensing plan that unifies its myriad existing business licensing agreements into a single new type of contract.
Currently, Microsoft offers a variety of volume-licensing plans for small, mid-size and enterprise customers. Those plans include everything from Select Plus, to Enterprise Agreements, to the Microsoft Online Subscription Agreement (MOSA) and the recently announced Server and Cloud Enrollment Plan
Under the new volume structure, there will be a single volume licensing agreement for all customers "regardless of size or type" with "integrated transactional purchasing for on-premises and Online Services." Customers will sign a "Foundational" Microsoft Products and Services Agreement (MPSA) to establish themselves and Microsoft will make available various "committed offers" to all customers.
