Per-user licensing is a pricing model in which a business pays for software or a service based on the number of people licensed to use it. Each named user, sometimes called a seat, carries a recurring fee, usually monthly or annually, regardless of how heavily that person uses the product. It is the most common way SaaS applications, unified communications, collaboration tools and productivity suites such as Microsoft 365 are sold to businesses.
At a glance
- You pay for each licensed person, typically per user per month or per year.
- Cost scales with headcount, which makes budgeting straightforward but means unused licenses still cost money.
- Tiers and add-ons often vary the price per user by feature set.
- Adding users is usually easy; reducing them mid-term is often restricted on annual or multi-year commitments.
- Contracts define who counts as a user, which matters for shared, part-time and contractor accounts.
What problem it solves
For buyers, per-user licensing makes cost easy to predict and allocate: a new hire adds a known monthly amount, and each department’s share is easy to calculate. It avoids large upfront license purchases and ties spend to the size of the workforce. For vendors, it creates recurring revenue that grows as customers grow.
The trade-off is that the cost does not follow actual use. People who barely use a tool cost the same as power users, and licenses for departed staff keep billing until someone removes them. Tracking assigned licenses against active people is how buyers keep per-user costs under control.
How it works
Named users. Each license is usually assigned to a specific person and can be reassigned when that person leaves, subject to the vendor’s rules.
Tiers and add-ons. Vendors commonly offer several plans at different prices per user, plus add-ons such as calling plans, advanced security or extra storage, also priced per user. Mixing tiers across the workforce is often allowed and can save money.
Terms. Monthly plans offer flexibility, often at a higher per-user price. Annual or multi-year terms lower the price but commonly fix the minimum license count for the term, with additions allowed and reductions only at renewal.
True-ups. Some contracts count users periodically and bill for any increase, either automatically through the admin portal or through a formal annual reconciliation.
Variations. Some products charge per device, per concurrent user, by usage or with a flat platform fee instead, and some mix models.
For tracking licenses across many subscriptions, SaaS management platforms show which seats are assigned and which are actually used.
When it matters for buyers
- At renewal. Compare licenses paid for against active users, and right-size before committing to another term.
- When downsizing. Annual commitments may keep you paying for licenses you no longer need until the term ends.
- When choosing tiers. Not every user needs the top plan; assigning tiers by role can cut cost.
- When staff leave. An offboarding process that removes or reassigns licenses prevents paying for departed users.
- When comparing vendors. Quoted prices per user are only comparable when tiers, add-ons and terms match.
Questions to ask vendors
- How do you define a user, and how are shared mailboxes, service accounts and contractors counted?
- Can we reduce the number of licenses during the term, and if so, when and how?
- What is the price difference between monthly, annual and multi-year terms?
- Which features require a higher tier or a paid add-on?
- How do true-ups work, and how are added users priced mid-term?
- Can we mix license tiers across different groups of users?
How it differs from per-device and concurrent licensing
Per-user licensing charges for each named person, whatever devices they use. Per-device licensing charges for each machine or phone, regardless of how many people use it, which can suit shared workstations or shift workers. Concurrent licensing charges for the maximum number of people using the product at the same time, so a pool of licenses can be shared across a larger group. Usage-based pricing, common in cloud and software as a service (SaaS) products such as messaging or storage, charges for consumption instead. Per-user terms are also often paired with a minimum annual commitment or a minimum license count.
