Microsoft sells software through six purchasing programs, four user license metrics, three device license metrics, and two consumption pricing structures. The combination decides the unit price, the audit posture, and the renewal leverage available to the buyer. The map below is the one procurement carries into every Microsoft conversation.
Microsoft licensing rests on three layers. The purchasing program that governs the contract. The metric that governs the count. The product that governs the entitlement.
Six programs cover the enterprise market. Enterprise Agreement, Microsoft Customer Agreement for Enterprise, Microsoft Products and Services Agreement, Cloud Solution Provider, Open Value, and the Microsoft Online Subscription Program. Each carries a distinct audit posture, renewal cadence, and negotiation lever.
Read this alongside the Microsoft knowledge hub, the EA Renewal Playbook, the EA post discount negotiation article, the Power Apps plan article, and the Vendor Shield subscription.
Microsoft sells through six enterprise relevant programs. Each program is a contract framework, not a product. The product entitlements travel across programs with different commercial mechanics.
| Program | Term | Billing | Best fit |
|---|---|---|---|
| Enterprise Agreement (EA) | Three years | Annual | 500+ seats, named SKU price hold |
| Microsoft Customer Agreement for Enterprise (MCA E) | Evergreen | Monthly | Flexible enterprise, cloud led estate |
| Microsoft Products and Services Agreement (MPSA) | Perpetual licenses, three year SA | Annual or one time | Mixed perpetual plus cloud, partner led |
| Cloud Solution Provider (CSP) | Monthly or annual | Monthly | Mid market, partner led, flexibility |
| Open Value | Three years | Annual | Smaller volume, transitional buyers |
| Microsoft Online Subscription Program (MOSP) | Monthly | Monthly | Self serve cloud, small footprint |
Most Microsoft cloud SKUs are licensed per user. Four user license metric variants appear in the contract.
Microsoft still ships device metric SKUs for shared device scenarios, plus per core metrics on data center products.
Azure runs on a consumption metric. Five commercial structures coexist on top of the pay as you go rate card.
| Workload | Pay as you go anchor | Common discount path | Indicative saving |
|---|---|---|---|
| General compute VM | Hourly rate per size | Three year Reservation plus AHB | 50% to 80% |
| SQL Database | vCore hourly rate | Reserved capacity plus AHB | 40% to 65% |
| Storage | GB per month rate | Reserved capacity | 15% to 40% |
| Networking | Egress per GB rate | Volume commit tier | 10% to 20% |
| OpenAI Service | Token rate per model | Provisioned throughput unit | 20% to 50% |
Client Access Licenses still appear in on premises Microsoft estates. They are not legacy in the contractual sense, only in the deployment sense.
Microsoft 365 E3 includes the user CAL bridge for Exchange, SharePoint, and Skype for Business Server. The Windows Server CAL still applies separately for any user accessing Windows Server services. Track CAL coverage carefully on hybrid estates, particularly on customers running both an on premises Exchange or SQL Server estate and a Microsoft 365 tenant.
Match the program to the workload posture, not the other way around. The right program drops the negotiation effort and lifts the discount ceiling.
The program governs the contract. The metric governs the count. The product governs the entitlement. Get the program right and every other Microsoft negotiation runs from a stronger base.
Use the seven step buyer side checklist below to set the Microsoft program and metric mix before the next renewal or estate review.
The Enterprise Agreement is the long established three year volume licensing framework for customers above 500 seats. It carries an annual true up, a named SKU price hold for the term, and a defined renewal cycle. Microsoft Customer Agreement for Enterprise is the evergreen replacement now positioned for new and renewing enterprise customers. It carries monthly billing, no true up, public list price as the commercial anchor, and a flexible move toward consumption pricing on cloud SKUs.
CSP stands for Cloud Solution Provider. It is the Microsoft partner led monthly subscription program. Customers buy Microsoft cloud services through a Microsoft partner who acts as the agreement holder. CSP suits mid market customers who want monthly flexibility on user counts and product mix. Above 500 seats the Enterprise Agreement or MCA E typically deliver a deeper discount ceiling, though specific partner CSP arrangements can match or exceed EA pricing on selected workloads.
A Client Access License gives a user or device the right to access a Microsoft Server product such as Windows Server, Exchange Server, SharePoint Server, or Skype for Business Server. CALs come in per device and per user metrics. They still apply across most on premises Microsoft Server deployments. Microsoft 365 E3 includes a User CAL bridge for several server workloads, but the Windows Server CAL remains separately required.
Azure Hybrid Benefit lets customers apply existing Windows Server or SQL Server licenses with active Software Assurance to Azure compute, reducing the Azure billable rate. On Windows Server, the benefit removes the Windows portion from the Azure VM rate. On SQL Server, the benefit removes the SQL portion. The combined saving on a three year Reserved Instance with Azure Hybrid Benefit applied regularly exceeds 70% of the pay as you go list rate.
A Step Up is a Microsoft commercial mechanism that lets a customer move from a lower SKU to a higher SKU mid term, typically from Microsoft 365 E3 to E5 or from Office 365 E3 to E5. The Step Up price is the difference between the lower and higher SKU prices, prorated to the remaining term, with credit for unused entitlement on the lower SKU. Step Ups are most commonly executed at an EA anniversary or true up.
