Microsoft EA vs CSP vs MCA. Choosing the right agreement.

Microsoft sells the same products under three commercial frames. The Enterprise Agreement (EA), the Cloud Solution Provider channel (CSP), and the Microsoft Customer Agreement for Enterprise (MCA E). The agreement choice changes the discount, the term, the billing model, and the audit posture.

Microsoft sells under three commercial frames. The Enterprise Agreement (EA) for organizations of 500 plus users on a 3 year term. The Cloud Solution Provider channel (CSP) for monthly or annual subscriptions through a partner. The Microsoft Customer Agreement for Enterprise (MCA E) for direct Azure consumption on a pay as you go basis.

The frame choice determines the discount tier, the price lock, the term, the billing model, the support inclusion, and the audit posture. Choosing the wrong frame typically adds 12 to 30 percent to the cloud spend over the term.

Key Takeaways

What every Microsoft customer needs to know about agreement choice

  • Three frames. EA, CSP, MCA E. Each has a different discount, term, and billing model.
  • EA fits 500 plus users. 3 year term, price lock, volume discount tier, true up at the anniversary.
  • CSP fits smaller orgs and flexible buys. Monthly or annual subscriptions through a partner, no minimum commit.
  • MCA E fits pure Azure consumption. Pay as you go consumption with Azure Reservations and Savings Plans for committed discount.
  • Discount math differs. EA volume discount on Microsoft 365 typically 8 to 15 percent. CSP partner margin replaces EA discount. MCA E carries published Azure list with reservation discount layered.
  • Support differs. EA does not include Unified Support. CSP often includes partner support. MCA E carries Azure support tier selection.
  • Mix is normal. Most large enterprises hold an EA for M365 and Azure base plus CSP for specific subscriptions and MCA E for Azure overflow.

Three Microsoft frames, side by side

The Microsoft frame choice depends on company size, deployment model, term horizon, and partner strategy.

When each frame fits

  • EA. Large organization with predictable Microsoft 365 and Azure base, 3 year horizon, internal procurement capacity.
  • CSP. Mid market, growing organization, partner managed environment, or a frame for specific subscriptions inside a larger EA estate.
  • MCA E. Pure Azure customer, no Microsoft 365 deployment, technical buyer in IT, willing to manage consumption.
  • Hybrid. Most large enterprises run a mix. EA for the M365 base, CSP for the regional sales subscription, MCA E for Azure overflow.

EA scope and commercial mechanics

The Microsoft Enterprise Agreement is the traditional volume licensing frame for organizations of 500 plus qualified users. The EA bundles Microsoft 365, Windows, Office, server and CAL, Power Platform, Dynamics 365, and Azure under one commercial frame.

EA commercial mechanics

  • 3 year term. Locked discount level for the term, with anniversary true up for added users.
  • Volume discount levels. Level A (500 to 2,399 users), Level B (2,400 to 5,999), Level C (6,000 to 14,999), Level D (15,000 plus).
  • Enterprise Online Services pricing. Microsoft 365 priced at level tier with multi year commit discount on top.
  • Azure prepayment. Monetary commit at the EA, drawn down against Azure consumption at preferred rates.
  • True up mechanism. Annual reconciliation of added users at the anniversary at the EA discount level.

Level C6,000 to 14,99912 to 14 percentUp to 5 percent
Level D15,000 plus14 to 15 percentUp to 5 percent

CSP scope and commercial mechanics

The Cloud Solution Provider channel sells Microsoft cloud services through a partner. The partner buys at wholesale rates from Microsoft and sells at retail to the customer, with partner margin replacing Microsoft direct discount.

CSP commercial mechanics

  • Monthly or annual subscription. No 3 year term lock, full flexibility on add and remove.
  • Partner margin. Partner sets the margin within Microsoft published wholesale rates. Margins vary 4 to 15 percent.
  • NCE pricing model. New Commerce Experience (NCE) introduced 2022. Annual commit gets discount over monthly commit. Monthly carries 20 percent premium.
  • Partner support included. Many CSP partners bundle support inside the subscription price.
  • Promotional offers. Microsoft periodically runs CSP promotions (e.g. 15 percent off Copilot for new annual commits).

When CSP beats EA

  • Sub 500 user organizations. EA volume thresholds do not apply.
  • Highly seasonal businesses. Monthly add and remove flexibility valuable.
  • Promotion driven buys. Microsoft CSP promotions on specific SKUs.
  • Partner managed environments. Partner provides M365 management, security operations, identity governance.

MCA Enterprise scope and commercial mechanics

The Microsoft Customer Agreement for Enterprise (MCA E) is the direct Azure consumption frame. MCA E customers pay Microsoft directly for Azure consumption at published list rates, with Azure Reservations, Savings Plans, and Microsoft Azure Consumption Commitments (MACC) layered on top.

MCA E commercial mechanics

  • No upfront commit required. Pay as you go consumption on monthly billing.
  • Azure Reservations. 1 or 3 year reserved capacity for specific VM SKUs. 38 to 72 percent discount on reserved scope.
  • Azure Savings Plans. Hourly compute commit across VM SKUs for 1 or 3 years. 11 to 65 percent discount.
  • MACC. Microsoft Azure Consumption Commitment, multi year Azure commit. Unlocks Enterprise grade discount on top of Reservations.
  • Per second billing. Most Azure services billed by the second or minute.

Worked example: 8,400 user enterprise

A global financial services firm runs 8,400 Microsoft 365 E5 users plus 14M USD per year Azure consumption. The renewal opens at a 3 year EA with EA Azure prepayment. The buyer side analysis compares EA, hybrid EA plus MCA E, and full MCA E plus CSP.

Scenario 1: 3 year EA, all in

LineYear 13 year total
M365 E5 at 50 USD per user per month, Level C 14 percent discount4.34M USD13.02M USD
Azure monetary commit14.00M USD42.00M USD
Total18.34M USD55.02M USD

Scenario 2: EA for M365, MCA E for Azure

LineYear 13 year total
M365 E5 EA Level C 14 percent discount4.34M USD13.02M USD
Azure MCA E with 3 year MACC and Reservations11.20M USD (20 percent saving)33.60M USD
Total15.54M USD46.62M USD
Saving vs EA scenario2.80M USD8.40M USD

Recommendation

  • EA for M365 base. 8,400 users with predictable 3 year horizon, EA Level C discount, multi year commit on top.
  • MCA E for Azure. 3 year MACC plus Reservations and Savings Plans on the steady state workload, pay as you go for development and test.
  • CSP for specific subscriptions. Regional Copilot pilot through a partner with bundled change management.
  • Saving. 8.40M USD over the 3 year term vs the all in EA scenario.

Seven Microsoft agreement levers

The seven levers procurement carries

  1. Frame selection. EA, CSP, MCA E, or hybrid. The single largest commercial decision.
  2. Volume tier threshold. Push the user count over the next EA tier where the math supports.
  3. Multi year commit. Trade the term length for additional discount on top of the tier.
  4. Azure split. Hold Azure on MCA E with MACC, run M365 on EA, use Reservations and Savings Plans.
  5. CSP partner selection. Run a competitive RFP across 3 to 5 partners for specific subscriptions.
  6. Promotional offer capture. Time the renewal to Microsoft fiscal quarter end (March, June, September) and active CSP promotions.
  7. Support unbundling. Remove Unified Support from the EA scope, source separately on a competitive basis.

What to do next

The checklist takes a Microsoft commercial position through the agreement frame decision.

  1. Inventory the current Microsoft estate. M365 SKUs, Azure consumption, Power Platform, Dynamics 365, server and CAL.
  2. Map each line to the right frame. M365 base on EA, Azure workload on MCA E, specialty subscriptions on CSP.
  3. Build three scenarios. All EA, hybrid EA plus MCA E, full MCA E plus CSP. Compare 3 year TCO.
  4. Run CSP RFP. Source the CSP scope competitively across 3 to 5 partners.
  5. Time the renewal. Target Microsoft fiscal quarter end and active promotional windows.
  6. Open the EA negotiation. Lead with the volume tier, multi year commit, Azure structure, and support unbundling.
  7. Document the frame map. Which subscription on which frame, with renewal dates and commercial terms.

Frequently asked questions

Is the EA being discontinued?

Microsoft has signaled the EA program will continue for large enterprise customers through 2026 and beyond. New customer enrollments below 2,400 users have been transitioning to MCA E and CSP since 2023.

Existing EA customers with 500 plus users continue to renew on EA terms, though Microsoft has tightened true down restrictions. The buyer side response is to validate the EA value at every renewal against MCA E and CSP alternatives.

Can we mix EA and CSP and MCA E in one estate?

Yes. Most large enterprises run a hybrid mix. EA for the M365 and Office base, CSP for specific subscriptions where partner support adds value, and MCA E for direct Azure consumption with Reservations and Savings Plans layered. The frame choice can be made subscription by subscription, not just estate wide.

The procurement discipline is to document which subscription sits on which frame, with renewal dates and commercial terms tracked separately.

What is the New Commerce Experience (NCE) on CSP?

NCE is the CSP commercial model Microsoft introduced in 2022. NCE introduces three subscription terms: monthly, annual, or 3 year. Monthly subscriptions carry a 20 percent premium over annual. Annual subscriptions lock the price for 12 months with full upfront billing or monthly installments. 3 year subscriptions lock further with additional discount.

NCE changed the flexibility profile of CSP. The monthly add and remove flexibility now carries a meaningful price premium, narrowing the CSP value proposition where pure flexibility was the driver.

How does Azure pricing differ on EA vs MCA E?

Azure list rates are the same on EA and MCA E. The differences sit on the discount mechanics. EA carries EA tier discount on Azure consumption inside the monetary commit, but EA Azure prepayment expires at the EA term end. MCA E uses Azure Reservations, Savings Plans, and MACC, which carry through term boundaries and stack across subscription types.

For pure Azure customers running 5M USD plus annual consumption, MCA E with a 3 year MACC and Reservations typically beats EA Azure prepayment by 8 to 18 percent.

Is Unified Support included in the EA?

No. Microsoft Unified Support is a separate purchase from the EA. Unified Support is priced as a percentage of the EA spend, typically 6 to 12 percent depending on the support tier (Core, Advanced, Performance). Many customers procure Unified Support automatically with the EA because of the convenience, missing the opportunity to source competitively.

Premier Support (predecessor to Unified) was retired in 2021. Customers can now source third party Microsoft support from partners at 30 to 60 percent below Microsoft Unified list, with comparable SLAs.

How does Redress engage on Microsoft agreement strategy?

Redress runs Microsoft agreement strategy inside the Vendor Shield subscription, the Microsoft services practice, the Software Spend Assessment, and the Renewal Program. The output is a frame selection map, a volume tier analysis, an Azure structure recommendation, a CSP partner RFP, a support unbundling analysis, and a renegotiated commercial position.

The engagement is led by Microsoft commercial professionals on the buyer side. We have run Microsoft agreement advisory across pharma, banking, manufacturing, retail, public sector, and technology customers running Microsoft estates from 2M to 120M USD per year.

The Microsoft agreement frame is the single most important commercial decision at the renewal. EA Level C versus MCA E with MACC can swing the 3 year TCO by 8 to 18 percent on a steady state Azure workload. The frame choice deserves its own analysis.
