Microsoft 365 Licensing
Microsoft 365 licensing.
Microsoft 365 pricing is decided long before the discount. It is decided by which tier each person sits on, and that is the lever most estates leave untouched.

Microsoft 365 is licensed per named user across a handful of plan families, and the whole cost story comes down to placing each person on the lowest tier that still covers their real work.
This guide is for procurement and IT leaders who need a working model of how Microsoft 365 licensing actually prices a workforce. Read it with the E3 vs E5 vs F3 comparison and the Microsoft Practice page.
Microsoft 365 licenses the person, not the device. A named user license follows the employee across every device they use, so the unit of cost is the headcount on a given tier. Microsoft sets out the plan structure on its plans and pricing page.
Device based licensing is now a narrow case for shared and kiosk scenarios such as shop floor terminals. For almost every office and remote worker, the per user model is the rule, and shared device thinking only creates confusion.
Microsoft 365 splits into Enterprise, Business, and Frontline families. The family you can buy depends on size, and the tier you should buy depends on the work.
Microsoft 365 plan families
| Family | Who it is for | Core tiers |
|---|---|---|
| Enterprise | Organizations of any size | E3, E5 |
| Business | Under 300 seats | Basic, Standard, Premium |
| Frontline | Deskless and shift staff | F1, F3 |
| Add ons | Specific needs | Security, voice, compliance |
The Business plans carry a 300 seat ceiling. Past that, an organization moves to the Enterprise plans. Microsoft documents the limit in its setup planning guide. Estates straddling the cap should reconcile their counts before renewal.
E5 pays off for the specific users who use its premium security, compliance, and voice capabilities. For everyone else, E3 covers the productivity core at a lower price. The premium is a targeted tool, not a default. Microsoft details the tier on its Microsoft 365 E5 page.
The standard advice is to standardize the whole organization on E5 so everyone has the full feature set and you simplify administration. We disagree. Across the estates we reviewed, 10 to 20 percent of E5 seats belonged to people who never touched a premium feature, and frontline staff routinely sat on E3 when an F SKU fit. Standardizing up is convenience funded by licenses nobody uses. The buyer side move is to place each person on the lowest tier their real work requires, reserve E5 for security, compliance, and voice users, and move deskless staff to F SKUs. Uniform tiers are easy to manage and expensive to own.
Frontline staff who work in a browser and on a phone fit the F SKUs, not full E3 seats. F3 adds web and mobile Office and a small mailbox, while F1 covers identity, Teams, and apps access for the lightest users.
Review placement every quarter against the active usage report. Roles change, people leave, and tiers drift upward without a routine. A quarterly pass keeps the seat count and the tier mix aligned to the work people actually do.

Microsoft 365 cost is decided by tier placement long before it is decided by the negotiated rate.
Microsoft 365 is licensed per named user, not per device. A single user license follows the employee across up to five PCs, five tablets, and five phones, so the unit of cost is the headcount assigned to each plan tier rather than the machines they use.
The main Microsoft 365 families are Enterprise with the E3 and E5 tiers, Business with Basic, Standard, and Premium under a 300 seat cap, and Frontline with the F1 and F3 SKUs for deskless staff. Add ons layer security, voice, and compliance on top.
E3 covers the productivity core that most knowledge workers need, while E5 adds premium security, advanced compliance, and voice. E5 pays off only for the users who actually use those premium capabilities, so most workers are correctly placed on E3.
One Microsoft 365 user license covers up to five PCs or Macs, five tablets, and five phones for that named person. The same seat works at home, in the office, and on the road, because the license attaches to the user rather than any device.
The Microsoft 365 Business plans carry a 300 seat ceiling. An organization above that count moves to the Enterprise plans, so estates near the limit should reconcile their seat counts before a renewal locks them into the wrong family.
Frontline workers who operate in a browser and on a phone should be licensed with the F SKUs, not full E3 seats. F3 adds web and mobile Office with a small mailbox, while F1 covers identity, Teams, and apps access for the lightest deskless users.
Microsoft 365 spend leaks through users placed on tiers above their work, frontline staff on full E3 seats, idle seats left after staff leave, and standalone add ons that duplicate features already inside the assigned plan. All are recoverable with a usage review.
Review Microsoft 365 licensing every quarter against the active usage report. Roles change and tiers drift upward without a routine, so a quarterly pass keeps the seat count and the tier mix aligned to the work people actually do before renewal.
