Types of Software Licenses and When Each One Applies
Most buyers meet their license model twice. Once at signup, and once at renewal.
The second meeting is the expensive one, because the terms were set in the first.
Software licenses come in six shapes a business meets.
What separates them is what you own, what you rent, and what happens the day you stop paying.
The types of software licenses below cover almost every contract a team signs.
Choosing between them drives renewal cost, audit exposure and how easily you can leave.
The Short Version
- Perpetual licenses buy the version you have today, not next year’s.
- Subscription licenses rent access, and access ends when billing ends.
- Open source licenses cost nothing to install and plenty to ignore.
What a Software License Grants
A software license grants permission to run a copy under stated conditions, and nothing beyond those conditions.
You aren’t buying the software. You’re buying a defined right to use it, and the definition is where the money hides.
Three clauses decide almost everything that follows.
How long the right lasts, how the vendor counts the people using it, and what you’re allowed to do with the code.
The Six License Types You Will Meet
Each model answers those three clauses differently. Most contracts blend two or three of them.
Perpetual Licenses
A perpetual license buys the right to run one version indefinitely.
The version is the catch. Fixes, security patches and new releases arrive through a separate maintenance contract, and when that lapses the software keeps running while the support stops.
It suits stable tools that don’t need to change: design software on an isolated workstation, a machine controller, a plant system with a ten year service life.
Subscription Licenses
A subscription license rents access for a billing period, and access ends when payment ends.
Updates and support are bundled rather than bought separately, which is why the sticker looks smaller and the ten year total often doesn’t.
This is the default for anything delivered as SaaS, and it’s the model that makes leaving cheap and staying expensive.
Open Source Licenses
An open source license grants the right to read, modify and redistribute the source code.
Free to install is not free to run. Hosting, upgrades and the engineering hours to keep it alive land on your team instead of a vendor’s.
Terms differ sharply on one point: whether changes you make must be published back. Permissive terms let you keep them private, and copyleft terms don’t.
Freemium Licenses
A freemium license gives away a limited tier and charges for the parts a working team needs.
The limit is rarely a feature. It is usually seats, storage, history or export, so the product works until the moment it matters.
Treat the free tier as an evaluation, not a plan.
Floating Licenses
A floating license is shared from a pool and counts concurrent use rather than headcount.
Twenty engineers can share eight licenses when they work in shifts, and the ninth person waits for one to free up.
It rewards uneven usage and punishes a team that all logs in at nine.
Named User Licenses
A named user license is assigned to one person, whether that person opens the software or not.
Reassignment is usually restricted to a fixed window, which is how leavers keep costing money for a quarter after they go.
It’s the simplest model to audit and the easiest one to overbuy.
How License Sprawl Starts
Sprawl starts with a purchase nobody recorded, not with a purchase nobody needed.
A team buys seats on a card, a project adds a floating pool, a department renews something the finance team stopped tracking two years ago.
The gap that matters is between entitlements, meaning what you bought, and deployments, meaning what’s installed. Reconciling those two records is the whole job of license management software, and it’s the number a vendor audit asks for.
Teams usually find the same three things: seats assigned to people who left, duplicate tools bought by different departments, and maintenance renewing on software nobody opens.
Matching a License Model to How Your Team Works
Start from usage patterns, because usage decides which model is cheapest long before the price list does.
| If your team | Then the cheaper model is usually |
|---|---|
| Works in shifts or uses the tool occasionally | Floating |
| Has everyone in the same tool daily | Named user |
| Runs software that rarely changes | Perpetual with maintenance |
| Needs the newest release every quarter | Subscription |
| Has engineers who can maintain it | Open source |
Then check the exit before you sign. Ask what you keep if you stop paying, how your data comes out, and what reassigning a seat costs.
A model that’s cheap to enter and impossible to leave isn’t cheap.
Software License Questions Buyers Ask
What are the main types of software licenses?
The main types of software licenses are perpetual, subscription, open source, freemium, floating and named user. The first two set how long your rights last, the next two set what you pay, and the last two set how the software counts your people. A single contract often combines three of them.
Is a perpetual license cheaper than a subscription?
A perpetual license costs more upfront and less per year, until the maintenance contract lapses. Once it does, you keep running the version you bought and stop receiving fixes. Teams that renew maintenance every year for a decade rarely save anything, and teams running stable software for a decade often save a lot.
Does open source software mean free software?
No, open source describes the terms on the source code rather than the price of running it. You can read, change and redistribute that code, and some terms require you to publish your changes. Hosting, support and engineering time are still yours to fund.
What is the difference between floating and named user licenses?
The difference is what each one counts. A floating license is shared from a pool and counts people using the software at the same moment. A named user license is tied to one person whether they open it or not, so shift-based teams pay less on floating.
Who is responsible when a software audit finds a shortfall?
The buying company is, in almost every contract. The vendor invoices the gap between what you deployed and what you bought, priced at list rather than your negotiated rate. That is why entitlement records matter more than install counts.
Start With the Licenses You Already Own
Pull your renewal calendar for the next ninety days and put three columns beside each line: what was bought, what’s deployed, and who last opened it.
Most teams can’t fill the third column, and that blank is the negotiating position they’re giving away.
Fix it before the renewal call, not during it.
