Dynamics 365 is also available through CSP and generally follows the NCE commerce model similarly to Microsoft 365 (seat-based subscriptions with term options), but its specific licensing structure (modules, user types like full users vs. "Team Members," and add-ons) is distinct from Microsoft 365's plan structure, since the products serve very different purposes (CRM/ERP vs. productivity).
If you're licensing Dynamics 365 for the first time, it's worth getting partner guidance specifically on Dynamics licensing, since the module/user-type structure is more involved than typical Microsoft 365 plans.
