Per-User Versus Per-Device Software Licensing
How to choose between per-user and per-device licensing models.
Software vendors usually price seats in one of two ways: per user or per device. The model that looks cheaper on paper is not always the one that costs less in practice. Choosing the wrong model leads to over-licensing, compliance risk, or frustrated employees sharing logins.
This article breaks down how each model works, where each one fits, and what to watch for in your contracts.
Per-device licensing
Per-device licensing counts every endpoint that runs the software. Each laptop, workstation, server, or mobile device needs its own license. This model is common for operating systems, endpoint management tools, and device-level security products.
When it fits
- Employees use one dedicated device most of the time
- The software runs on shared kiosks, terminals, or shop-floor machines
- You need to license servers, printers, or IoT devices
- Device count is stable and easy to track
Watch-outs
- Costs grow quickly when employees have multiple devices
- BYOD policies complicate license counts
- Replacing or reimaging devices can consume activations
Per-user licensing
Per-user licensing assigns one license to each named individual, regardless of how many devices that person uses. Most SaaS products use this model because it matches how people actually work: from a laptop, phone, tablet, and browser.
When it fits
- Employees switch between multiple devices during the day
- The product is cloud-based and accessed through a browser
- You want predictable budgeting tied to headcount
- Remote and hybrid work are common
Watch-outs
- Inactive or forgotten users can go unnoticed without regular audits
- Service accounts, contractors, and shared mailboxes may still need separate treatment
- Some vendors define "user" differently, such as by active login or named identity
How to decide
| Scenario | Usually better choice |
|---|---|
| One device per employee, fixed workstation | Per-device |
| Multiple devices per employee, mobile workforce | Per-user |
| Shared devices or shift workers | Per-device or concurrent licensing |
| Cloud SaaS accessed from anywhere | Per-user |
| Server operating systems or virtual machines | Per-device or per-core |
Read the contract carefully
Vendors use terms like "named user," "authorized user," "active user," or "concurrent user" in different ways. Before you sign, confirm:
- Whether the license is tied to a person, a login, or a device
- What happens when an employee leaves or a device is replaced
- Whether reassigning a license requires vendor approval or incurs a fee
- How the vendor audits usage and what penalties apply
