Compare MPSA and CSP Licensing Models

Learn about the feature equality and management differences between MPSA and CSP perpetual licenses.

Perpetual licenses for Microsoft Office, Project, and Visio have the exact same software features regardless of whether they are purchased through a Microsoft Products and Services Agreement (MPSA) or the Cloud Solution Provider (CSP) program. The software functionality is identical.

The actual differences lie entirely in how you purchase and manage these licenses. MPSA uses traditional volume licensing channels, while CSP routes purchases through a partner-managed cloud model.

Identify your purchasing model

Determine your organization's agreement type: MPSA represents a traditional volume licensing agreement, while CSP operates on a partner-led subscription-based purchasing model.

Manage MPSA licenses

To manage MPSA, navigate to the Microsoft Volume Licensing Service Center (VLSC) portal. From here, administrators can download software, access license keys, and manage traditional volume purchases.

Manage CSP licenses

To manage CSP purchases, log into the Microsoft 365 admin center. This single portal allows administrators to oversee licenses, assign seats to end-users, and handle billing.

Feature Parity: Because the desktop applications are exactly the same, your end-users will not notice any difference in software capabilities or interface design regardless of which licensing route your organization chooses.
