20 pages. Dynamics 365 is one of Microsoft's most commercially opaque product lines. The base and attach licence architecture, the Team Member tier, the Dual-Use Rights with Power Apps, and the interaction between D365 modules and Microsoft 365 licences create a cost structure that almost no enterprise fully understands — until the first renewal quote arrives. This guide changes that.

Dynamics 365 licences are priced as base licences and attach licences. The attach pricing is only available to users who already hold a qualifying base licence — and the rules for what qualifies change periodically. This guide explains the current model and how to use it to reduce costs.
Dynamics 365 full-capability licences are priced as "base" licences. Additional modules for the same user are available as "attach" licences at 20–50% of the base module price. The qualification rules — which base licences unlock which attach licences — determine your optimal module sequencing. The full base/attach compatibility matrix for Finance, Sales, Supply Chain, Customer Service, Field Service, and HR modules.
The Dynamics 365 Team Member licence at $8/user/month provides read access to data from any D365 application and limited write access to specific entities. Most organisations over-license light users on full module licences. The Team Member use rights, the capability restrictions, the interaction with Power Apps licences, and the scenarios where Team Member is a legitimate replacement for full module licensing.
Dynamics 365 licences include rights to create and use Power Apps and Power Automate flows within the D365 environment. These Dual-Use Rights are frequently overlooked — enterprises that separately license Power Apps for D365 users are double-paying. The full Dual-Use Rights entitlements by D365 module, the boundary conditions, and how to restructure your Power Platform licensing to eliminate redundancy.
External users — customers, suppliers, and partners — who access Dynamics 365 data through portals require separate licensing. The Power Pages (formerly Power Apps Portals) licensing model applies to customer-facing deployments. The external user licensing options, the authenticated vs. anonymous user rules, and the capacity-based pricing model that replaces per-user pricing for high-volume external user scenarios.
Dynamics 365 is negotiable within the Enterprise Agreement, but the negotiation dynamics differ from M365. Microsoft account teams have less discount authority on D365 — significant pricing concessions typically require executive escalation. The discount structures available (typically 10–30% off list), the commit-and-grow structures that provide pricing protection for planned user growth, and the timing considerations relative to ERP go-live schedules.
Microsoft Copilot for Dynamics 365 was released in 2023 and is now embedded across Sales, Customer Service, Finance, and Supply Chain modules. The Copilot capabilities included in standard D365 licences versus those requiring the Dynamics 365 Copilot add-on, the per-user pricing, the interaction with Microsoft 365 Copilot licences, and how to evaluate ROI before committing to Copilot at scale within D365.
Each pattern is covered in the guide with the correct licensing structure, the cost impact calculation, and the EA negotiation approach to remediate without disrupting operations.
In most Dynamics 365 deployments, 30–50% of named users are light users who primarily read data, approve transactions, or perform a small number of simple write operations. These users typically qualify for Team Member licensing at $8/user/month — compared to $65–$210/user/month for full module licences. The failure to identify and re-classify light users is the most common source of Dynamics 365 overpayment in enterprise deployments.
Enterprises deploying multiple D365 modules frequently license each module independently at full price rather than structuring purchases as base licences with attach licences. A user requiring both D365 Sales and D365 Customer Service should be licensed as Sales (base) plus Customer Service (attach at 50% of list) — not as two full-price module licences. This structural error is common in organisations where D365 licences were procured incrementally by separate business units.
Dynamics 365 full user licences include Power Apps Dual-Use Rights for applications built on the D365 platform. Organisations that separately license Power Apps per-user plans for their D365 user base — typically because different procurement teams manage the two products — are paying twice for the same capability. Consolidating Power Apps licences for D365 users under Dual-Use Rights removes this redundancy entirely.
The Dynamics 365 Licensing Guide is written for CIOs, ERP programme leads, and procurement leaders who are navigating D365 deployments, expansions, or EA renewals. It assumes no prior Dynamics licensing knowledge — and builds from first principles to advanced negotiation strategy.
This 2026 edition covers the updated Copilot for Dynamics 365 pricing announced in Q4 2025, the revised Team Member use rights following the 2025 licensing guide update, and the new Power Pages capacity-based pricing model for external user deployments.

"We were licensing 800 users on full D365 Sales licences. After the guide's light-user analysis framework, we reclassified 340 as Team Members and restructured our Sales + Customer Service users on a base/attach model. The combined saving was $1.1M annually — without changing a single user's access to the data they needed."
