Microsoft EA vs CSP: Should Your Organization Make the Switch?

Microsoft has steadily evolved its licensing models over the years—and for many mid-sized organizations, the choice between Enterprise Agreement (EA) and Cloud Solution Provider (CSP) has become more relevant than ever.

While Enterprise Agreements (EA) remain the right choice for certain large enterprises and complex environments, Microsoft is increasingly encouraging organizations with up to 2,400 users to evaluate the flexibility and financial advantages of its Cloud Solution Provider (CSP) model. New incentives, simplified management, and cloud-first product strategies are all driving this shift.In this post, we’ll break down the key differences between EA and CSP — and the factors mid-sized organizations should evaluate when deciding which approach is right for them.

What Is Microsoft Enterprise Agreement (EA)?

Enterprise Agreements have long served larger organizations with more complex IT environments. Key features include:

  • 3-year contractual terms
  • Upfront commitments with volume discounts
  • Software Assurance benefits
  • Support for both cloud and on-premises deployments
  • EA remains a strong fit for organizations with highly complex or hybrid environments, significant on-premises infrastructure, or long-term licensing predictability needs.

What Is Microsoft Cloud Solution Provider (CSP)?

CSP enables organizations to purchase Microsoft licenses through authorized partners on a subscription basis. With CSP, you get:

  • Monthly subscription billing
  • Ability to scale licenses up or down as business needs change
  • No long-term commitments
  • Full access to Microsoft 365, Azure, Dynamics 365, Power Platform, and other services
  • Partner-delivered support, billing, and account management

Microsoft has been steadily evolving CSP to better serve cloud-centric businesses that value flexibility and operational simplicity.

5 Key Reasons Mid-Sized Organizations Are Moving to CSP

1. Licensing Flexibility

Unlike EA’s fixed annual true-up process, CSP allows you to adjust license counts each month as headcount changes. This is especially valuable for organizations that experience:

  • Rapid growth or contraction
  • Seasonal workforce fluctuations
  • Mergers, acquisitions, or divestitures

CSP’s flexibility helps avoid over-purchasing licenses and eliminates the uncertainty of annual true-up payments.

2. Simplified Budgeting

With CSP, licensing costs scale directly with usage and are billed monthly. This allows finance and IT teams to:

  • Align expenses with actual employee counts
  • Avoid large, unpredictable renewal charges
  • Manage licensing like other SaaS subscriptions

While EA can still offer volume-based discounts for very large deployments, many mid-sized organizations find CSP’s transparency and simplicity easier to forecast and manage.

3. Premium Support at No Additional Cost

Under EA, organizations receive Microsoft’s baseline support unless they invest in premium tiers separately.

When partnering with MCPC through CSP, clients receive premium-level support at no additional cost, including:

  • Faster response times
  • Direct escalation pathways to Microsoft
  • Proactive guidance from MCPC’s Microsoft-certified experts

For many IT teams, this support model adds meaningful value and helps reduce internal resource strain.

4. Administrative Simplicity

EA often requires significant administrative oversight to track compliance, manage renewals, and complete annual reconciliations.

CSP removes much of that complexity with:

  • Transparent monthly billing
  • No annual audits or true-ups
  • Simplified contract management

This allows organizations to focus IT resources on higher-value activities instead of ongoing license administration.

5. Alignment with Microsoft’s Licensing Strategy

Microsoft continues to introduce incentives and partner programs that favor CSP adoption. Current CSP discounts can exceed 15% off standard pricing, with more flexibility built into the partner ecosystem.

While EA remains appropriate for some large or highly customized organizations, Microsoft’s long-term roadmap is increasingly oriented toward CSP for mid-market and cloud-first customers.

When EA Still Makes Sense

It’s important to evaluate both models carefully. EA may remain the better option for organizations that:

  • Exceed 2,400 users
  • Maintain significant on-premises infrastructure
  • Require advanced Software Assurance benefits
  • Have unique contractual or compliance needs

Choosing the right model depends on your organization’s size, technical environment, and business priorities.

Best Practice: Start Evaluations 6-12 Months Before Renewal

To make an informed decision, organizations should begin evaluating their licensing options 6 to 12 months before renewal. This allows sufficient time to:

  • Complete a full licensing assessment
  • Analyze current and projected license utilization
  • Compare financial models across EA and CSP
  • Build a smooth transition plan if a change is warranted

MCPC works directly with organizations to navigate this assessment process and help select the model that best supports long-term goals.
