Microsoft EA vs CSP: Which Microsoft Licensing Model Fits Your Organization?

Microsoft EA vs CSP

Executive Summary: Enterprises must decide between Microsoft’s Enterprise Agreement (EA) and the Cloud Solution Provider (CSP) program.

An EA offers predictable costs and volume discounts over a multi-year term, while a CSP provides pay-as-you-go flexibility with minimal commitment.

This article compares EA vs. CSP in cost, contract commitment, support, and flexibility to help CIOs and IT leaders determine which licensing model best meets their organization’s needs.

Read how to negotiate your Microsoft Enterprise Agreement.

The decision between Microsoft’s Enterprise Agreement (EA) and a CSP licensing model requires balancing cost stability against flexibility. Enterprises must weigh the long-term volume discounts and predictability of an EA against the agility and month-to-month scalability of a CSP. In practice, the right choice depends on organization size, budget strategy, and how quickly user counts or cloud consumption may change.

Cost Structure and Pricing

Upfront Commitments vs. Pay-as-You-Go:

Under an EA, organizations negotiate pricing for a 3-year term and often receive volume discounts based on the number of licenses (Level A–D pricing tiers for larger user counts).

This yields lower per-user costs for big enterprises and locks in pricing for the full term, providing budget certainty. By contrast, CSP pricing is typically subscription-based with no large upfront payment – you pay monthly for what you use.

While CSP has flexibility, its per-license prices can be slightly higher for large volumes (partners may add a small margin). Enterprises qualifying for high-tier EA discounts sometimes find CSP less cost-effective per unit.

In contrast, smaller organizations or those with fluctuating needs often save money by not over-buying licenses. Notably, many companies switching from EA to CSP report 10–20% cost savings by eliminating unused licenses and optimizing monthly spend.

Discounts and Price Changes:

An EA’s pricing is negotiated with Microsoft (often via a reseller LSP) and fixed for three years on the initial products – this protects you from Microsoft’s annual price hikes during the term.

CSP pricing, on the other hand, can adjust more frequently. Typically, a CSP subscription locks the price for the duration of that subscription (e.g., 12 months if you choose an annual term), but month-to-month plans have no long-term price protection.

Microsoft can (and does) periodically increase cloud service prices, and CSP customers may see these changes after their term ends or even month to month.

EA customers get price protection for licenses in the agreement, and can plan budgets knowing costs won’t rise until renewal. However, if Microsoft introduces a new product or feature during the EA term, adding it might come at the current list price (unless you negotiated a discount upfront).

In CSP, partners set the pricing. They may offer promotional discounts or bundle savings, but pricing varies by provider and generally follows Microsoft’s list with some markup.

Always compare the 3-year Total Cost of Ownership (TCO) under each model: a higher unit price in CSP could still lead to lower total spend if you can scale down licenses during slow periods.

Hybrid Cost Approach:

Some enterprises use a mix of EA and CSP to optimize costs. For example, they keep core users on an EA to get volume discounts on major products, but use CSP for seasonal workers, contractors, or new projects to avoid long-term commitments.

This hybrid strategy ensures high utilization on the EA (preventing wasted licenses) while leveraging CSP’s pay-per-use for transient needs.

In the table below, we summarize how key cost and licensing factors differ between EA and CSP models:

Commitment Length and Flexibility

Contract Commitment:

A Microsoft EA requires a three-year commitment. You sign a formal contract and must pay for a certain number of licenses (and/or a certain Azure spend) for the duration.

This long-term commitment benefits organizations with stable or growing user counts by locking in discounts and pricing.

The downside is rigidity: if your employee count shrinks or you need fewer licenses, you generally cannot reduce your license count until the EA term ends. (There is an annual “true-up” process to add more licenses if you grow, but reducing, often called “true-down,” is not permitted mid-term for most products.)

In contrast, CSP agreements are inherently flexible. There is typically no overarching contract term beyond the subscription choices you make. You can go month-to-month on many licenses, or opt for a 1-year or 3-year subscription for better rates on certain products – but it’s your choice per product.

This means no long lock-in: you could increase or decrease license quantities as your needs change, with as little as a month’s notice. CSPs’ lack of long-term obligation is a major advantage for organizations with fluctuating workforces or project-based usage.

Scaling Up or Down:

With an EA, scaling up is straightforward (you add licenses and true-up the payment annually at the agreed price), but scaling down is difficult. You are essentially “stuck” with the initial quantity until renewal, which can lead to overpaying for unused licenses if your needs drop.

Some EA customers negotiate special clauses for one-time or flexible reductions at the anniversary, but these are not standard. CSP by design allows scaling both up and down. You can provision new licenses anytime through the partner portal and pay the prorated cost in the next invoice.

Likewise, you can remove licenses (or unsubscribe) – if on a month-to-month plan, you just don’t renew them for the next month; if on an annual term, you can set them not to renew at year’s end or reduce the count. This elasticity ensures you “pay for what you use, when you use it.”

The trade-off is that CSP’s flexibility comes with shorter price lock periods (for instance, a 1-year subscription under CSP fixes the price for one year, but at renewal, the cost could change).

In summary, EA is about commitment and predictability, whereas CSP is about agility and adaptability. Organizations expecting significant changes (mergers, divestitures, rapid growth, or contraction) will appreciate CSP’s ability to adjust quickly.

Conversely, those with steady-state IT environments might manage fine within an EA’s fixed structure.

Support and Service Considerations

Support Model:

One often overlooked difference is how support is handled. Under an Enterprise Agreement, support for Microsoft products is not included in the licensing cost – enterprises typically purchase a Premier/Unified Support contract separately if they want direct Microsoft support.

This can be costly (Unified Support fees are often a percentage of your license spend) and provides 24/7 access to Microsoft’s support engineers for issues. With CSP, support is provided by the CSP partner as part of the service. Reputable CSP partners include at least basic support in your subscription cost – for example, help with cloud service issues, user management, and incident routing.

Many CSP partners offer 24/7 technical support and advisory services without extra fees (or with tiered support packages). If you have an issue with a Microsoft 365 service or Azure workload, you contact your provider, and they handle troubleshooting or escalate to Microsoft on your behalf.

For organizations that don’t have a dedicated Microsoft support agreement, CSP can fill the support gap by delivering more personalized service.

Conversely, an EA customer with a paid Microsoft support plan might access Microsoft’s higher-tier support directly, whereas a CSP customer’s issues go through the partner first.

However, top-tier (Direct CSPs) are highly capable and often resolve common issues directly. They also know your environment well, providing proactive guidance that Microsoft’s generic support might not.

Account Management and Services:

In an EA, Microsoft (or the reseller) will have an account manager who helps with license management and renewals, but day-to-day license administration is up to your IT team. CSP partners often act as an extension of your team by managing licenses, monitoring usage, and even optimizing costs.

For example, a CSP might regularly review your subscriptions and suggest downgrading or removing underused licenses, thereby saving you money – something Microsoft wouldn’t actively do under an EA. CSPs can also bundle value-added services: training, migration assistance, or custom solutions, making the relationship more service-oriented.

In terms of portals and admin, EA customers use Microsoft’s standard admin portals (Microsoft 365 admin center, Azure portal, etc.). They may also use a Licensing Portal for ordering through their LSP. CSP customers use the same Microsoft admin centers but may also get access to the partner’s portal that consolidates all subscriptions, billing, and support tickets in one place.

This can simplify administration by having a single pane of glass for all your Microsoft services with that provider. If your organization prefers a hands-on partner experience with support and management included, CSP is appealing.

If you have a strong internal team and perhaps already invest in direct Microsoft support, an EA keeps those aspects separate and under your control.

Customization and Contract Terms

Negotiation and Flexibility of Terms:

A notable difference is the ability to customize terms. Enterprise Agreements are formal contracts where large enterprises often negotiate custom clauses or amendments to suit their needs. For instance, you might negotiate an addendum for special pricing protections, flexibility to swap products, or other concessions unique to your business.

Microsoft is willing to consider these (especially for large deals) because of the long-term commitment. Examples of custom EA terms include: extended price lock for an extra year, the right to license transfers in case of mergers, or adding a contractual cap on renewal price increases.

In contrast, the CSP program uses standardized terms and agreements that are generally not negotiable per-customer basis (the contract is usually the partner’s service agreement and Microsoft’s uniform customer agreement).

In a CSP arrangement, you have less leverage to change terms like liability, data location, or termination rights; it’s typically a take-it-or-leave-it subscription model. The CSP focuses on flexibility in licensing, not on negotiating the fine print of each customer’s contract.

Therefore, organizations with complex requirements, such as specific privacy clauses or the need for dedicated contract language, might prefer an EA where they can work with Microsoft to include those provisions.

Product Coverage and Future Needs:

An EA can cover virtually all Microsoft offerings – from traditional on-premises licenses (Windows, Office, Server CALs) to cloud services (Microsoft 365, Azure).

It’s a single agreement to enroll the products you need. CSP primarily covers cloud subscriptions (Microsoft 365, Dynamics 365, Azure plans, etc.), though in recent years, Microsoft has also allowed CSP partners to sell perpetual software licenses.

If you have significant on-premises licensing requirements or Software Assurance benefits to maintain, an EA might be simpler.

However, for cloud-focused organizations, CSP covers the needed subscriptions without the overhead of legacy products. Consider future needs too: if you plan to adopt new Microsoft technologies (AI services, new security products), an EA ensures you have a framework to add them with pre-negotiated discounts.

With CSP, you can still get anything new immediately (that’s one advantage – no need to amend a contract; you just subscribe when it’s available), but the cost will be at whatever price the partner sets at that time.

In summary, EA is a more structured arrangement that you can bend to your needs via negotiation. In contrast, CSP is standardized but agile, easy to start and change, but not individually tailored via contract terms.

Choosing the Right Model for Your Organization

Enterprise Agreement Fits Best When:

Organizations that are large (500+ seats) and have relatively stable IT demand often lean towards an EA. If you value predictable budgeting over three years and qualify for substantial volume discounts, the EA can provide lower per-user costs for enterprise suites like Microsoft 365.

Companies with dedicated procurement processes may also prefer the EA’s fixed yearly true-up cycle (aligning with budgeting cycles). Additionally, suppose you require customized contract terms (for example, specific data handling terms or guaranteed pricing for a future project). In that case, an EA gives you a platform to negotiate with Microsoft.

Enterprises that have invested in Microsoft-centric infrastructure (e.g., using Windows, Office, SQL Server broadly) often consolidate everything under an EA for convenience and holistic discounting. Finally, the EA aligns well if your internal processes or policies favor signing enterprise-wide agreements to formalize vendor relationships.

CSP Model Suits Best When:

Businesses that need agility and scalability will benefit from CSP. If your user count fluctuates (seasonal workers, high-growth startups, or companies frequently reorganizing), the ability to add or remove licenses monthly prevents overspending.

CSP is also ideal for smaller organizations or those below EA thresholds; you can access the same cloud services without meeting a 500-user minimum. Organizations with limited IT admin capacity appreciate the partner-managed support and simplified billing.

CSP can also be a better fit if you’re primarily cloud-first and don’t need the complexity of a big contract, for example, a company that only uses Microsoft 365 and Azure and wants to manage costs closely month to month.

It’s worth noting that some mid-sized companies that could do an EA still choose CSP because they value the partner’s service and advisory aspect and avoid a multi-year commitment in a fast-changing tech landscape.

Hybrid Approach:

Many enterprises don’t strictly choose one or the other – they might have an EA for core licenses and use CSP for specific needs. For instance, a global company might keep an EA for its headquarters and major sites, but let smaller subsidiaries or new acquisitions use CSP for flexibility until they’re folded into the next EA renewal.

Or use CSP just for Azure dev/test subscriptions while production Azure is under an EA commitment. This hybrid approach can yield the best of both: locking in discounts on predictable usage while keeping flexibility where needed.

Remember that Microsoft is evolving its licensing programs (the newer Microsoft Customer Agreement is another option for certain cases), so the classic EA vs CSP decision should consider any new offerings combining features of both.

Ultimately, assess your organization’s priorities—cost savings vs. risk of overcommitment, desire for flexibility vs. need for custom terms, and the importance of a direct Microsoft relationship vs. partner-led service.

The goal is to align the licensing model to your business model.

Recommendations

• Assess Your User and Spend Profile: Gather data on your license usage and growth projections. If you have 1,000+ steady users, an EA may yield better discounts; if usage is volatile, CSP can prevent overbuying.
• Calculate Multi-Year Costs: Model a 3-year total cost for both EA and CSP options. Include license fees, support costs, and potential waste from unused licenses. This TCO analysis often clarifies which model is financially superior for your scenario.
• Consider a Trial of CSP: If you’re coming off an EA, try moving a subset of licenses or a department to CSP during a renewal to test flexibility and partner support. A hybrid licensing strategy can optimize both cost and agility.
• Negotiate EA Wisely: If you pursue an EA, negotiate for the flexibility you need (e.g., adding new cloud services at locked discounts). Ensure any EA includes ad price protection and a plan for addressing downsizing (even if it’s just at renewal).
• Leverage Partner Value: A good CSP partner can provide guidance on license optimization, cost management tools, and responsive support. Evaluate CSP providers not just on price, but on the extra services and expertise they offer your IT team.
• Keep Future Plans in Mind: If major changes (merger, cloud migration, etc.) are on the horizon, lean towards the model that accommodates them. Don’t lock into a huge 3-year commitment if you might overhaul your IT architecture in a year. Conversely, if you’re confident in steady growth, lock in an EA discount before prices increase.
• Review Support Needs: If you lack a Microsoft support agreement, the included support from a CSP could be valuable conversely, if you require direct Microsoft Premier/Unified Support, budget that cost on top of an EA’s license fees.
• Stay Informed on Licensing Changes: Microsoft licensing programs evolve. Watch for new programs like the Microsoft Customer Agreement for Enterprise (MCA-E) that combine EA and CSP aspects. Being open to new models can ensure you always get the best terms available.
• Vendor Management Strategy: Align the licensing choice with your vendor management preferences. If you want a single throat to choke and a deeply involved account team, an EA via a licensing partner might suit you. A CSP partner acting as an advisor is ideal if you prefer a more service-oriented relationship with ongoing optimization.
• Reevaluate at Renewal: The decision isn’t once-and-done. Whichever route you choose, revisit it every three years (or annually for CSP). Your business may evolve—ensure your Microsoft licensing model evolves with it for maximum benefit.

FAQ

Q1: What’s the biggest mistake enterprises make when choosing between EA and CSP?
A1: The biggest mistake is not thoroughly analyzing their usage and growth. Some companies assume an EA is the default for enterprise and overcommit to a 3-year agreement, ending up paying for hundreds of unused licenses. Others avoid an EA due to fear of commitment when they could have saved money with the volume discounts. Always base the decision on data, current license utilization, projected changes, and the total cost over time, rather than simply sticking with what you did last time.

Q2: Can an organization use both an EA and CSP at the same time?
A2: Yes, many do. This hybrid approach can be very effective. For example, an enterprise might cover its baseline of 5,000 users under an EA to get bulk pricing, but acquire additional licenses via CSP for short-term projects, contractors, or new acquisitions. Microsoft allows this and sometimes even encourages using CSP for certain scenarios. Just be cautious when managing both agreements so you don’t double-pay or run into compliance issues (avoid unnecessarily assigning two different licenses to the same user).

Q3: Which model offers better discounts on Microsoft 365 or Azure – EA or CSP?
A3: For large, steady workloads, an EA typically offers better discounts because Microsoft provides volume-based pricing tiers, and you negotiate upfront. For instance, a Level D EA (very large enterprise) might get 15-20% off the list price of Microsoft 365 E5. CSP pricing for Microsoft 365 is usually closer to the list price (though some partners may give small discounts or bundle deals). However, for Azure, it can be case by case – EA often involves committing to a certain Azure spend to get a discount, whereas CSP Azure might be pay-as-you-go, but sometimes partners have “CSP Azure plans” with discounts (~5%–12%) for high spend levels. If your usage is small or fluctuating, the difference in unit price might be less important than the ability to turn things off (CSP). EA’s locked-in discounted rate for consistently high usage usually wins on pure pricing.

Q4: How does license management differ under EA vs CSP?
A4: With an EA, you typically true-up annually, meaning you report any increases in usage once per year and get billed for them. You maintain compliance by counting installations or users internally. There’s an EA portal for ordering, but much of the tracking is manual on the customer side or via a reseller. In CSP, license management is more continuous – you can add or remove licenses through the partner’s portal anytime, and billing adjusts automatically during the next cycle. CSP provides real-time visibility into what licenses you have active, simplifying staying in compliance (you can’t exceed usage because you’re provisioning licenses as needed). EA might give you some leeway (30 days to report ads), whereas CSP is immediate. Overall, CSP tends to be more user-friendly for administrators day-to-day, whereas EA requires periodic true-up exercises and careful planning at renewal.

Q5: Can we switch to CSP before the EA expires if we have an EA?
A5: Generally, no – you are contractually committed to the EA for its full term (usually 3 years). You could start a CSP subscription for some new services or new users not covered by the EA, but you can’t simply abandon the EA without potentially paying penalties for the remaining term. Most organizations wait until the EA is close to expiration, then evaluate whether to renew it or migrate to CSP. It’s a good practice to start that analysis 6-12 months before your EA ends. Microsoft and your reseller will likely push for a renewal, possibly offering concessions; meanwhile, CSP providers would be happy to help you transition. Plan the cutover carefully if moving to CSP so there’s no gap in licensing.

Q6: Is Microsoft’s Enterprise Agreement being phased out in favor of CSP or the newer Microsoft Customer Agreement?
A6: Microsoft has been evolving its licensing models. CSP and the Microsoft Customer Agreement (MCA) are relatively newer programs that simplify procurement, especially for cloud services. Microsoft has hinted at moving smaller customers off the traditional EA over time (for example, those under 2,400 seats might eventually use MCA or CSP instead). However, the EA is still very much alive for medium and large enterprises. We see Microsoft giving customers more options – some direct, no-term agreements (MCA) and the ongoing CSP model through partners. It’s possible that in the future, EA and CSP will converge into a more unified model. But any phase-out will be gradual. If you’re eligible for an EA and it suits you, there’s no problem signing a new one today; just be aware of changes coming down the road by 2025–2026.

Q7: How do Azure commitments work under EA vs CSP?
A7: In an EA, you often commit to a certain Azure monetary spend over the 3-year term (e.g., “Azure prepaid $500k over 3 years”). In exchange, Microsoft might give you a discount on Azure consumption or some free credits. You then draw down from that committed fund. If you exceed it, you pay overages; if you under-use it, you typically still pay for the commitment (use or lose it). Under CSP, Azure is typically billed pay-as-you-go monthly with no long-term commitment, although Microsoft has introduced the “Azure plan” in CSP, which can also have some commitment discounts or savings plans. The key difference is that EA provides price lock and potential discounts for commitment, but you must accurately forecast your 3-year Azure usage. CSP provides flexibility – you only pay for what you consume each month and can stop at any time, but the rates might be a bit higher unless you use reserved instances or the CSP’s own enterprise plan. CSP is safer if you’re unsure about your Azure growth or don’t want to risk overcommitting. If you know you will spend a large amount, an EA commitment can shave off costs (just negotiate what happens if you underspend – sometimes you can get that money reallocated to other services).

Q8: What about Software Assurance and benefits like training days – do those differ in EA vs CSP?
A8: Software Assurance (SA) is included by default on most EA licenses for on-prem software, granting benefits like upgrade rights, training vouchers, home use rights, etc. In CSP, the concept of Software Assurance doesn’t exist in the same way for cloud subscriptions – cloud services inherently include updates and new features. However, if you buy perpetual licenses through CSP’s new commerce, you might not get all the traditional SA perks (or you’d have to add them separately). One notable difference: EA customers with SA had access to things like Planning Services and support incidents (which Microsoft has been phasing out or converting to new programs). CSP subscriptions (like Microsoft 365) include some end-user services (e.g., Office 365 comes with web support, etc.), but the extra training days or workshops are not a built-in feature of CSP. If those benefits are important, you might miss them under CSP unless the partner compensates with their own offerings. We see Microsoft moving to a model where SA benefits are less of a differentiator and more value is delivered via cloud subscription itself and partner services.

Q9: How does renewal work for EA vs CSP?
A9: An EA runs for 3 years, after which you have a renewal (or expiry). At renewal, you negotiate a new 3-year term – it’s a chance to adjust what you’re buying (drop products, add new ones) and renegotiate pricing. Many enterprises see price increases at renewal if not negotiated carefully, because Microsoft’s list prices may have risen, or discounts may change. With CSP, there isn’t a “contract” to renew in the same sense; instead, each subscription (license type) you have will come up for renewal on its own cycle (if annual, each year you renew that subscription). You can decide to continue, adjust quantity, or even switch providers relatively easily at those points. Think of CSP renewal as more continuous – you’re always in a monthly/annual cycle that you can extend or not. One benefit is you can spread out decisions (you don’t have one giant renegotiation event); one downside is you have to keep an eye on various subscription end dates. Many CSP partners will manage and remind you of renewals. Also, CSP pricing could change year to year, so at renewal of a 12-month term, you might see a 5% price uptick if Microsoft raised prices. You’d have been insulated from that in an EA until the big renewal negotiation.

Q10: If my organization prefers working directly with Microsoft, is EA the only option?
A10: Historically, EAs were sold via large account resellers, so you weren’t exactly “direct with Microsoft” – you worked through a Licensing Solution Provider (LSP) and a Microsoft account team. CSP is sold through a partner (Microsoft’s Cloud Solution Providers), which might feel one step further removed from Microsoft. If having a direct relationship is important (for example, you want Microsoft’s attention and resources), an EA or the newer Microsoft Customer Agreement might be preferable. That said, Microsoft still pays attention to big CSP customers, especially if your Azure consumption is high, as Microsoft will be involved via the partner. The Microsoft Customer Agreement (MCA) is a direct purchasing method (no reseller) that some enterprises are moving to for Azure and Microsoft 365, essentially replacing direct EAs in some cases. It’s more akin to CSP’s flexibility, but directly with Microsoft. So, if you do not want a reseller, talk to Microsoft about MCA options. In summary, an EA ensures you’re on Microsoft’s radar with a dedicated account manager and engineering resources for your deployment; a CSP adds an intermediary who can advocate for you but is ultimately the one providing your licensing. Many companies find a strong CSP partner gives them better service than they got by going direct, but it depends on the partner’s quality.
