Microsoft volume licensing explained
Microsoft licensing has evolved over the years and continues to provide options for organisations to make the most of their technology. Having the correct type and number of Microsoft licenses in place is important to ensure your users can access the tools they need as is the capability to successfully manage and control them.
Understanding which type of licenses, you need can be complicated and expensive without the right advice and recommendation. The type of license agreement you need can depend on many factors such as:
- Which products or product suites you want to purchase
- Industry sector
- Number of users and/or devices
- Length of contract
- How you choose to consume them
- How you want to pay for them
- Where you buy them from

Types of Volume Licensing Agreements
Enterprise Agreements

An Enterprise Agreement (EA) is a volume license agreement that offers best value to an organisation more than 250 users/devices for Public Sector customers or 500 users/devices in the private sector. EAs provide a range of products that include software assurance, access to online services and subscriptions.
Split into enterprise-wide products (mandatory) and additional products for a committed 3-year period, organisations can take advantage of higher levels of discount, fixed pricing, a wider range of products, subscriptions and services and via partnerships that can use additional funding for project support.
EAs are also available as an on-premises model (EA) that supports the provision of perpetual licenses or as a Cloud subscription model (ESA) that offers non perpetual option at a reduced cost.
With a supporting agreement of the server cloud enrolment which provides discounts against core infrastructure, application platform, developer platform and Azure for an install-based commitment.
Server and Cloud Enrolment components:
Windows Server System Centre
SQL Server BizTalk Server
Visual Studio
Microsoft Azure
The EA structure incorporates an annual review and a balance check for a true up (purchase of additional licenses) or annual count to ensure that it still meets the original brief and adheres to Microsoft programmatic rules. All of which is part of the management process that Trustmarque will help advise and guide you through as a standard service within our account review.
The commitment associated with Enterprise Agreements help to unlock additional services from Trustmarque and Microsoft in the form of funding requests, on application to Microsoft and the delivery of our Microsoft FastTrack services.
