Microsoft EA vs. CSP: Choosing the Right Licensing Path

When it comes to Microsoft licensing, most organizations are choosing between two main paths: the Enterprise Agreement (EA) and the  Cloud Solution Provider (CSP) model. Both are strong options, but they’re designed with very different needs in mind. Understanding the difference can help you decide which model delivers the most value for your business.

Enterprise Agreement is Microsoft’s traditional model and has been around for decades providing volume discounts and predictable costs. While Cloud Solution Provider, on the other hand, was designed for the cloud-first, fast-moving business world we live in today.

Let’s break it down and what to consider when making your choice. 

Comparing EA & CSP Licensing 

What is an Enterprise Agreement (EA)?

The Enterprise Agreement is Microsoft’s traditional licensing model.

• Who it’s for: Large organizations (usually 500+ users or devices) with predictable, high-volume needs.
• How it works: Multi-year contracts (typically 3 years) with a committed upfront spend and volume-based discounts.
• Billing & Flexibility: You “true-up” licenses once a year, meaning it’s harder to quickly add or remove users mid-year.
• Support: Managed directly by Microsoft. Support packages sold separately.

EA is best suited for large enterprises with stable IT needs as it’s predictable and usually cost-effective at scale. If you’re a global enterprise with thousands of employees and well-defined IT needs, EA can be the smart choice.

What is a Cloud Solution Provider (CSP)?

The Cloud Solution Provider model was designed for today’s cloud-first world. Instead of buying direct from Microsoft, you purchase licensing through a partner (like Coretek).

• Who it’s for: Organizations that desire flexibility and value-added services out of their Microsoft partnership.
• How it works: Month-to-month or annual subscriptions with no minimum seat requirements.
• Billing & Flexibility: Pay-as-you-go, scale licenses up or down anytime, predictable monthly billing.
• Support: Your partner (Coretek) is your first line of support, and often adds services, cost optimization, and hands-on help.

CSP is a great option for businesses that are looking for that personalized support, flexibility, scalable licensing options, and cost-efficient without the long-term lock-in of an EA. Perfect for dynamic organizations where headcount, budgets, or IT needs change often.

Key Differences at a Glance

Which One Should You Choose?

• Choose EA if… you’re a large enterprise that values stability, predictability, and volume discounts, and you’re ready to commit to a 3-year plan.
• Choose CSP if… you want flexibility, scalability, and partner support tailored to your business, whether you’re a growing startup, a mid-sized business, or even a larger company that doesn’t want to be tied down.

Why CSP is Rapidly Growing

Today’s businesses move quickly. Teams scale up or down. Projects shift. Mergers happen. In this environment, CSP shines because it:

• Eliminates long-term lock-in.
• Keeps licensing always current and compliant.
• Offers personalized support and cost-saving opportunities through partners.

With CSP, you’re not just buying licenses, you’re gaining a partner who helps you make sure every dollar spent in Microsoft’s cloud is delivering value.

Final Takeaway

Both EA and CSP have their place. EA works best for very large, stable organizations with predictable needs. CSP, on the other hand, gives you flexibility, agility, and a partner in your corner, which is why more and more businesses are choosing it as their path forward.
