Alternatively, the customer can sign a purely enterprise online service contract with Microsoft. This option does not require company-wide standardization. Customers must acquire at least 500 Enterprise online service licenses. In a three-year contract, the number of desktop computers and qualified users can be adjusted for each anniversary of the contract. This allows for greater flexibility to meet changing requirements. Use rights are limited and expire when the contract expires. Microsoft`s SCE program is a licensing program for standardizing Microsoft server products and allows customers to combine them with online services. It replaced the existing EAP and ECI programs as of February 1, 2014. SCE offers 4 components: Core Infrastructure, Application Platform, Developer Platform and Microsoft Azure. These programs can offer price advantages over the enterprise agreement. If you choose one of the first three components, customers will have access to Microsoft Azure in the best possible conditions.
When signing the agreement, the customer must define and communicate to Microsoft the number of desktop computers or qualified users as well as Microsoft Enterprise products or Enterprise Online Services. This information represents the first purchase. Each anniversary is due to a “True Up Order” for additional desktops or qualified users, based on which the total cost for the previous year is calculated. Under a traditional agreement on microsoft Enterprise, the customer is allowed to authorize corporate products individually or as a standard platform. However, at least one enterprise product must be standardized throughout the company. EA/SA (Enterprise Agreement/Software Assurance) is a volume licensing package offered by Microsoft. It is primarily aimed at large organizations with 500 or more personal computers. The minimum amount was increased from 250 to 500 on July 1, 2016, but remains at 250 for public sector clients.
 Other programs, including open value, Open License and Select License, are aimed at smaller organizations.
