Dynamics 365 Under an Enterprise Agreement (EA)
An Enterprise Agreement is a volume licensing contract for large organisations — typically requiring 500+ users or devices. It covers a 3-year term (occasionally 5 years) and is designed for enterprises standardising on Microsoft's suite. When Dynamics 365 is included in an EA, you commit to a set quantity of licences for the term, with negotiated pricing that locks in rates for the duration.
Commitment and Price Lock
You commit upfront to a set number of Dynamics 365 licences by product for a 3-year period. You can increase counts via annual true-ups, but you cannot decrease until renewal. This provides cost predictability — you know your base Dynamics 365 cost for 3 years — but it is inflexible if your needs drop. The EA locks pricing for the term, protecting you from list price increases on committed quantities. Additional licences added during the term are typically available at the same negotiated rate.
Volume Discounts
EAs typically provide 15 to 30% below list pricing for Dynamics 365, depending on total commitment and negotiation. Microsoft extends volume discounts within the EA, and enterprise customers can negotiate custom discounts on top of standard pricing. This discount level is not available through CSP or Web Direct channels. For large deployments (500+ users), the per-user savings over a 3-year term can represent $500K to $2M+ compared to list-rate CSP subscriptions.
Annual True-Up Process
EAs handle changes via annual true-up rather than monthly adjustments. If you exceeded licensed quantities during the year, you report and pay for additional usage once per year, backdated to when it was first used. If you scaled down, you cannot receive credit until renewal. The EA trades flexibility for stability — it assumes an upward or steady trajectory, not downsizing. For growing organisations, this is efficient; for organisations in transition, it creates waste.
Enterprise-Wide Reassignment
EA licences are enterprise-wide — you can reassign them internally without changing the agreement. If one division's user count drops and another's increases, you can shuffle licences since the EA is an org-wide contract. This internal flexibility partially offsets the lack of true-down: the total count is fixed, but allocation within the organisation is fluid.
Dynamics 365 via Cloud Solution Provider (CSP)
The Cloud Solution Provider programme is Microsoft's channel for purchasing cloud services on a subscription basis through a partner. CSP offers monthly or annual terms per licence, with the ability to add or remove subscriptions at each billing cycle — a fundamentally different model from EA's multi-year commitment.
Subscription Flexibility
CSP allows you to add or remove licences at each billing cycle — monthly for monthly subscriptions, or at the end of the annual term for annual subscriptions. This "pay only for what you use" model is ideal for variable staffing or seasonal usage. If you hire 100 contractors for a 6-month project who need Dynamics access, under CSP you add 100 licences for those months and remove them afterward. Under an EA, you would true-up and then be committed to those licences until the end of the 3-year term.
True-Down Capability
CSP's ability to reduce licence counts is its single biggest advantage over EA. If your company undergoes a reorganisation and 100 Dynamics users are no longer needed, you reduce those subscriptions and stop paying — effective at the end of the current billing period. In an EA, you continue paying for those 100 until the 3-year term ends. For organisations experiencing headcount volatility, M&A activity, or uncertain Dynamics adoption, this flexibility can save hundreds of thousands of dollars compared to being locked into an EA minimum.
List-Rate Pricing
CSP pricing is generally based on Microsoft's current list price (MSRP). Partners may offer a small discount (typically 3 to 8% from their margin), but the deep negotiated discounts achievable in an EA (15 to 30%) are not available. However, CSP's cost advantage comes from eliminating waste: many enterprises find that the savings from trimming unused licences via CSP's flexibility outweigh the higher per-licence price. Microsoft's New Commerce Experience (NCE) now offers 1-year and 3-year CSP terms that can lock pricing, blurring the line between CSP and EA.
Partner-Managed Support
With CSP, your first line of support is the CSP partner — not Microsoft directly. Microsoft expects partners to handle customer issues, escalating to Microsoft only when needed. This can be advantageous if the partner has strong Dynamics expertise (more personalised support), or a disadvantage if the partner is not responsive (an extra layer between you and Microsoft). Many large CSP partners include managed services, training, and adoption support as part of their value proposition.
EA vs CSP — Head-to-Head Comparison
| Dimension | Enterprise Agreement (EA) | Cloud Solution Provider (CSP) |
|---|---|---|
| Commitment | 3-year contract, 500+ user minimum | Monthly or annual per licence — no minimum |

| Price lock | Locked for 3-year term | Subject to list price changes (unless 1/3-year NCE term) |
| Scaling up | Add via annual true-up (backdated) | Add anytime, pay prorated going forward |
| Scaling down | No reduction until renewal | Reduce at next billing cycle |
| Payment | Annual upfront | Monthly billing (or annual pre-pay) |
| Support | Separate Unified Support agreement | Partner-provided (often included) |
| Relationship | Direct Microsoft account team | Through CSP partner → Microsoft |
| Administration | Full customer self-service | Self-service (some changes may involve partner) |
| Renewal | Major renegotiation every 3 years | Continuous — switch partner or model anytime |
| Best for | Large, stable deployments valuing best pricing | Variable, growing, or uncertain deployments valuing flexibility |
"The EA vs CSP decision is not binary — the most sophisticated enterprises use both. Core stable users on EA for maximum discount, variable and project-based users on CSP for flexibility. The hybrid approach captures the strengths of both models while mitigating their weaknesses."
The Hybrid Strategy — Best of Both Models
Core Users — Stable Base on Enterprise Agreement
Place your permanent, predictable Dynamics 365 user base on the EA: the 500 Sales Enterprise users who will be there for the full 3-year term, the 200 Finance users running core ERP processes, and the 300 Customer Service users in your contact centre. These users benefit from the EA's 15 to 30% volume discount without risk of paying for unused licences. The EA commitment for this stable base also contributes to your total Microsoft spend, which strengthens your negotiation position for Azure discounts, M365 pricing, and other EA components.
Variable Users — Flexible Layer on CSP
Place variable, seasonal, and project-based Dynamics 365 users on CSP subscriptions: contractors who need 6-month access, seasonal staff during peak periods, new business units where adoption is uncertain, and pilot groups for new Dynamics modules. CSP's monthly true-down capability means you only pay for these users when they are active. The slightly higher per-user cost (list rate vs EA discount) is more than offset by the elimination of waste. A 100-user CSP layer that averages 60 users over the year costs 40% less than committing to 100 EA licences used at 60% utilisation.
Cost Comparison — When Each Model Wins
The financial comparison between EA and CSP depends on two variables: per-user discount rate and licence utilisation rate. EA wins on price; CSP wins on waste elimination. The breakpoint determines which model delivers lower total cost.
| Scenario | Users Committed | Avg Monthly Active | Utilisation | EA Annual Cost (25% discount) | CSP Annual Cost (list) | Winner |
|---|---|---|---|---|---|---|
| Stable enterprise | 500 | 480 | 96% | $1,350,000 | $1,728,000 | EA (22% cheaper) |
| Growing company | 500 | 400 | 80% | $1,350,000 | $1,382,400 | Close — EA slightly cheaper |
| Variable workforce | 500 | 300 | 60% | $1,350,000 | $1,036,800 | CSP (23% cheaper) |
| Seasonal/project | 500 | 200 | 40% | $1,350,000 | $691,200 | CSP (49% cheaper) |
Breakpoint: At approximately 80 to 85% utilisation, EA and CSP costs converge. Above 85%, EA wins. Below 75%, CSP wins decisively. These calculations assume Sales Enterprise at $95/user/month list price with a 25% EA discount. Actual figures vary by product, negotiated rates, and partner terms — but the utilisation-driven dynamic is consistent across all Dynamics 365 modules. Before committing to either model, measure your actual utilisation rate across at least 6 months of data.
Considerations When Switching Between Models
EA to CSP — Timing and Transition
If you are moving Dynamics 365 from an EA to CSP, the optimal transition point is at EA renewal. Do not renew the Dynamics 365 component in the new EA; instead, establish CSP subscriptions to take effect when the current EA term ends. Ensure continuity of service — CSP subscriptions should be active before EA licences expire. Negotiate with your CSP partner for best available pricing, particularly if committing to annual or multi-year NCE terms. Verify that all Dynamics 365 data, configurations, and integrations are unaffected — the product itself does not change, only the billing and entitlement mechanism.
CSP to EA — Consolidation for Discounts
If your Dynamics 365 usage has grown and stabilised, consolidating from CSP into an EA can reduce per-user costs by 15 to 30%. The optimal moment is when you can confidently predict your minimum user count for a 3-year period. Negotiate the EA to include only the stable minimum — any users above that threshold can remain on CSP for flexibility. When transitioning, align the CSP subscription end dates with the EA start date. Cancel CSP subscriptions only after confirming EA licences are active and assigned.
Running Both Simultaneously — Governance
If using a hybrid model, implement clear governance to prevent confusion and double-licensing. Maintain a single licence management system that tracks which users are on EA versus CSP. Establish rules for when new users are added to EA (true-up) versus CSP (flexible subscription). Ensure procurement, IT, and finance all understand the two channels and their respective cost implications. Without governance, organisations risk paying for the same user on both EA and CSP — an expensive and common mistake in hybrid environments.
CIO Recommendations — EA vs CSP for Dynamics 365
Analyse Your User Stability
If 80%+ of Dynamics 365 users are permanent and predictable, EA delivers better value through volume discounts. If more than 30% of users are variable, CSP's flexibility may save more than EA's discount.
Consider the Hybrid Approach
Place your stable minimum on EA (at negotiated discount) and your variable layer on CSP (with monthly flexibility). This captures the best of both models.
Negotiate D365 Pricing Separately
Within your EA, negotiate Dynamics 365 discounts as a distinct line item — do not let Microsoft bundle D365 pricing into an overall discount that obscures the per-product rate.
Evaluate CSP Partner Value-Add
If using CSP, select a partner based on Dynamics 365 expertise, support quality, and willingness to pass through margin as discount — not just the lowest headline price.
Plan Transitions at EA Renewal
Any shift between EA and CSP should be timed to EA renewal. Mid-term transitions create overlap costs and administrative complexity.
Use CSP for New Module Pilots
When evaluating new Dynamics 365 modules (Field Service, Project Operations, etc.), use CSP's monthly subscriptions for the pilot — then move to EA if the module is adopted at scale.
Account for Total Microsoft Spend
Dynamics 365 EA commitment contributes to your total Microsoft spend, which affects Azure discount tiers and M365 pricing. Factor this "EA halo effect" into your cost comparison.
Implement Licence Governance for Hybrid
If running EA and CSP simultaneously, maintain a single source of truth for licence assignments to prevent double-licensing and ensure cost accountability per department.
Microsoft's New Commerce Experience (NCE) — Blurring the EA/CSP Line
Microsoft's New Commerce Experience (NCE) has introduced annual and multi-year term options within CSP that significantly blur the traditional distinction between EA and CSP. Understanding NCE is essential for CIOs evaluating their Dynamics 365 procurement strategy.
NCE Annual Subscriptions
NCE annual terms offer a 20% discount compared to monthly CSP pricing — narrowing the gap with EA volume discounts. An NCE annual subscription locks the per-user price for 12 months and provides a predictable cost basis. However, cancelling an NCE annual subscription mid-term incurs early termination fees (you pay for the remaining months). This means NCE annual is a middle ground: more flexible than EA (1-year vs 3-year commitment), cheaper than monthly CSP, but less flexible than monthly CSP for true-down. CIOs should use NCE annual for "semi-stable" users — those likely to remain for 12 months but where 3-year commitment is not justified.
Three-Tier Procurement Strategy
With NCE, the optimal approach becomes a three-tier model: (1) EA for the permanent base (maximum discount, 3-year commitment), (2) NCE annual CSP for semi-stable users (moderate discount, 1-year commitment), (3) monthly CSP for truly variable users (list pricing, maximum flexibility). This three-tier structure captures 90%+ of the cost optimisation opportunity while maintaining flexibility where it is needed. Map each Dynamics 365 user segment to the appropriate tier based on expected tenure and usage predictability.
Frequently Asked Questions
It depends on your utilisation rate. EA offers lower per-user pricing (typically 15 to 30% below list), but you pay for every committed licence regardless of usage. CSP charges list rates (with minor partner discounts), but you only pay for active users. The breakpoint: if your licence utilisation is consistently above 80 to 85%, EA is cheaper. Below that, CSP's flexibility to reduce unused licences often saves more than the per-unit discount difference. For a 1,000-user deployment at 70% utilisation, CSP typically costs 10 to 15% less than EA despite the higher per-user rate — because you are paying for 700 users instead of 1,000.
Yes — Microsoft supports running EA and CSP subscriptions for Dynamics 365 within the same tenant. This is the basis of the hybrid strategy: stable core users on EA for volume discounts, variable users on CSP for flexibility. The key governance requirement: ensure no user is double-licensed (assigned both an EA licence and a CSP subscription for the same product). Maintain a single licence management system that tracks the channel for each user assignment. From a technical perspective, both EA and CSP licences appear in the same Microsoft 365 admin centre — the distinction is billing and entitlement, not product functionality.
Nothing changes with your data, configurations, or integrations. Switching from EA to CSP (or vice versa) is a billing and entitlement change — not a platform migration. Your Dynamics 365 environments, customisations, data, users, and integrations remain exactly as they are. The transition is administrative: you establish CSP subscriptions to replace EA licences, assign users to the new subscriptions, and let the EA licences expire. The critical requirement is timing — ensure CSP subscriptions are active before EA licences expire to avoid any gap in service.
No — under standard EA terms, you cannot reduce your committed licence count during the 3-year term. You can increase via annual true-ups, but decreases are only possible at EA renewal. This is the EA's biggest limitation for dynamic environments. The workaround: internally reassign unused licences to other divisions or users (EA licences are enterprise-wide and reassignable). If reassignment is not possible, the unused licences represent sunk cost until renewal. To mitigate this risk, commit to a conservative minimum in the EA and handle additional demand through CSP's flexible subscriptions.
Five levers: (1) Negotiate Dynamics 365 as a separate line item — do not let Microsoft bundle it into a blended discount that obscures the per-product rate. (2) Use competitive alternatives (Salesforce, SAP, ServiceNow) as leverage — Microsoft is more aggressive on D365 pricing when they believe you have viable alternatives. (3) Commit to multi-year Azure spend as part of the EA — this gives Microsoft a larger total deal, creating room for D365 concessions. (4) Time your negotiation to Microsoft's fiscal quarter-end (June, September, December, March) when sales teams have quota pressure. (5) Negotiate escalator caps — ensure annual price increases are capped at 0 to 3% rather than Microsoft's standard 5 to 8% increases at renewal.
NCE is Microsoft's updated CSP billing framework that introduces 1-year and 3-year subscription terms alongside the traditional monthly option. With NCE annual or multi-year terms, you can lock in pricing similar to an EA (protecting against list price increases). NCE annual subscriptions are typically 20% cheaper than monthly subscriptions, narrowing the pricing gap with EA. However, NCE annual terms also reduce CSP's flexibility: cancelling an annual NCE subscription mid-term incurs early termination fees. CIOs should evaluate NCE terms strategically — use monthly for truly variable users, annual NCE for semi-stable users (cheaper than monthly but more flexible than EA), and EA for the permanent base.
For any Dynamics 365 deployment exceeding $500K annually, independent advisory provides significant value. The EA vs CSP decision involves complex trade-offs between per-user pricing, utilisation rates, growth projections, M&A scenarios, and the "EA halo effect" on total Microsoft spend. Independent advisors bring benchmark data from comparable engagements, knowledge of Microsoft's internal discount authority for D365, and experience structuring hybrid EA/CSP models that optimise for both cost and flexibility. The advisory investment is typically recovered within the first year through better pricing negotiation and elimination of licensing waste.
