Dynamics 365 rewards buyers who map every user to the cheapest qualifying license. This guide shows how base and attach works and where the seat mix hides your savings.
Dynamics 365 is licensed on a base plus attach model that rewards buyers who map roles to the cheapest qualifying license. This guide shows how the model works, where dual use rights cut cost, and the buyer side moves before your next renewal.
Dynamics 365 pricing looks simple on the web page. The cost lives in how you assign licenses to people.
Get the base license right for each role and the rest of the model works in your favor. Get it wrong and you pay full price many times over.
You pay full price once per user for a base license, then a reduced price for each additional app that user needs. The base is the anchor.
Each user's first qualifying Dynamics application is the base, charged at full list. Microsoft publishes these on the Dynamics 365 pricing page. Pick the base that matches the user's primary role.
Once a user holds a qualifying base, extra apps attach at a steep discount. A user in Sales who also needs Customer Service pays full price once and a small attach fee for the second app.
The table shows how the same two apps cost very differently depending on whether the second is bought as a base or an attach. Treat it as a frame for role mapping.
Two Dynamics 365 apps for one user
| Approach | First app | Second app | Relative cost |
|---|---|---|---|
| Two base licenses | Full price | Full price | Highest |
| Base plus attach | Full price | Discounted attach | Much lower |
| Team Members only | Light role price | Included scope | Lowest |
Full users run the heavy work. Team Members cover light roles. The split decides most of the bill.
A full user can run the complete functionality of an app, from creating opportunities to processing service cases. Microsoft sets the qualifying use in its Dynamics 365 licensing guide.
A Team Members license covers light tasks such as reading records, updating personal data, and limited write actions. It costs a fraction of a full user but its scope is fixed and narrow.
Most overspend hides here. People sit on full licenses for tasks a Team Members license covers. A role by role review is the fastest saving in any Dynamics estate.
Buy to real usage, not to job titles. The model gives you several cheaper paths if you map roles honestly.
Dual use rights let one licensed user access Dynamics across the web app, mobile, and the Outlook based client without buying separate licenses. Confirm them in the Microsoft product terms.

When a user needs a second app, buy the attach license, not a second base. Duplicate base licenses are the most common and most expensive Dynamics mistake we find.
Pull active usage by user and app. Reassign or drop seats that show no real activity. Do this before the renewal quote, not after you have signed it.
The standard partner pitch is that the route to savings is a bigger volume commitment, so you should consolidate spend and negotiate a deeper percentage discount. We disagree. In roughly 6 of 10 Dynamics estates we have reviewed, the discount was healthy but the seat mix was wrong, with full users sitting on tasks a Team Members license covered and second apps bought as duplicate base licenses. The buyer side move is to fix the role mapping first, because a 15 to 28 percent reduction in the wrong licenses beats another two points off the right ones.

Dynamics pricing is not won at the discount line. It is won in the seat mix, where one full user that should be a Team Members license repeats across the whole estate.
Renewal is where price increases land and where a stale seat count gets locked in for another term. Prepare it like a negotiation.
Microsoft has raised Dynamics list prices, so the renewal quote often carries an uplift on top of your current spend. Benchmark the new rate before you accept it.
Whether you renew through an Enterprise Agreement or through a partner on CSP affects price points, payment terms, and the freedom to flex seats during the term.
Start the usage review three to six months before renewal. The reduced, correct seat count becomes your negotiating baseline rather than a concession you ask for later.
You pay full price once for a user's base license, then a discounted attach price for each additional app that user needs. Each user needs only one base, so assigning the right base license and using attach for extra apps is the single largest saving in the model.
A Team Members license covers light roles such as reading records, running reports, and making limited updates, at a fraction of a full user. Its scope is fixed and narrow, so it suits people who consume data and make small edits rather than running the full process.
Use an attach license whenever a user already holds a qualifying base and needs a second app. Buying a second full base license for the same user is the most common and most expensive Dynamics mistake, often doubling that user's cost for no added right.
Dual use rights let one licensed user access Dynamics across the web app, mobile, and the Outlook based client without buying separate licenses. Confirm the current terms in the Microsoft product terms, because they prevent paying twice for the same user across interfaces.
It depends on your size and how much you need to flex seats. An Enterprise Agreement suits larger, stable estates, while CSP through a partner offers more month to month flexibility. Compare both on price, payment terms, and seat flexibility before you renew.
In our benchmarks role mapping recovered 15 to 28 percent of annual license cost before any discount was negotiated. The savings come from moving full users to Team Members where the role allows and converting duplicate base licenses to attach licenses.
Renewal is where Microsoft price uplifts land and where a stale seat count is locked in for another term. Start a usage review three to six months early, clean the seat count, benchmark any uplift, and renew on the corrected baseline rather than last term's numbers.
Yes. The Dynamics model rewards precise role mapping that vendors and resellers rarely do for you, because their incentive favors fuller licenses. Independent buyer side advisory builds the seat by seat plan and the renewal benchmark that recover cost across the estate.
Microsoft renewal moves, the EA framework, the seat mapping framework, and the buyer side moves across the full Microsoft and Dynamics estate.
Used across more than five hundred enterprise engagements. Independent. Buyer side. Built for procurement and IT asset leaders running the next renewal or audit cycle.
Dynamics is one of the few estates where the cheapest move is also the simplest. Map every user to the license their role actually needs, and the savings appear before you ever ask for a discount.
