A practical guide to software licence types in 2025
With licensing evolving as fast as the software it regulates, it can be hard to keep up - but that doesn't make it any less important to stay up to date.
Published on 3rd September 2025
Software licensing keeps evolving as fast as the software itself. If you’re planning roadmaps, negotiating renewals, or just trying to stay compliant, understanding software licence types in 2025 isn’t optional – it’s operational hygiene. Below you’ll find a clear tour of modern models, with tips to help you pick the right fit for your stack and budget.
Perpetual vs. Subscription: Where Each Fits in 2025
Perpetual licences are the old guard: pay once, run forever. They shine in stable environments, air-gapped networks, and use cases where major upgrades aren’t critical. But “forever” rarely includes support; you’ll often renew maintenance for patches and compatibility.
Subscription (SaaS) licences dominate 2025 because they package features, support, and security updates into a predictable OPEX line. They scale up or down with headcount and usage, let finance avoid big CAPEX spikes, and reduce upgrade friction. The trade-off is continuous spend and the need for strong offboarding to prevent orphaned renewals.
User-, Device-, and Usage-Based Licensing
Seat (named user) licensing ties a licence to a person. It’s great for role-based tools and audit clarity. Device licensing binds rights to a machine – useful for shared kiosks, labs, or VDI pools. Concurrent licensing caps simultaneous users regardless of how many accounts exist; if peaks are short, it can be cost-efficient.
Usage-based licensing (metered by API calls, compute time, data volume, or features used) is the rising star. It aligns cost with value delivered and suits variable workloads. The catch? You need strong telemetry and alerting or the bill can sprint ahead of expectations.
Open Source, Source-Available, and Commercial Open Source
Open source remains the backbone of modern stacks. Permissive licences (MIT, BSD, Apache-2.0) offer flexibility with minimal obligations. Copyleft licences (GPL family) require that derivative works remain open under similar terms – powerful for community protections, but challenging for proprietary distribution.
Source-available licences let you read the code but impose restrictions (for example, limiting cloud hosting of the software). Commercial open source mixes an OSS core with paid enterprise features and support. In 2025, clarity matters: document where each component lives, who maintains it, and which obligations (attribution, notices, disclosure) apply.
Enterprise Terms: EULA, Site, and OEM Licences
Enterprise EULAs increasingly bundle security commitments, data-handling clauses, and uptime obligations. Site licences grant broad rights across a location or company, simplifying large deployments. OEM and embedded licences allow you to ship software inside your product – ideal for hardware vendors and platform builders – but they demand careful version and vulnerability tracking across long lifecycles.
When negotiating, map terms to real operational behaviour: how you provision users, how frequently you update, where you run workloads, and how you’ll prove compliance during an audit.

How to Choose: A Simple Decision Checklist
Before you sign, run through these quick questions. The answers usually point to the best model – or a hybrid mix.
- Do users share devices or is access strictly personal?
- Will usage spike seasonally, or stay flat year-round?
- Is offline operation required for parts of the estate?
- How will you monitor, meter, and reclaim unused licences?
- What are your obligations if you redistribute or embed components?
Governance, Audits, and the Right Tools
Licence compliance scales poorly without robust discovery, entitlement tracking, and renewal workflows. Centralise contracts, map entitlements to real installations, and automate alerts for over-assignment or orphaned subscriptions. Mature IT asset management and service management platforms help inventory software, align entitlements with actual usage, and produce audit-ready evidence on demand. Pair that with a clean de-provisioning process and quarterly true-ups to keep surprises off your finance reports.
Trends to Watch Through 2025
Vendors are blending models: subscriptions with usage floors, “platform” bundles with feature toggles, and dual-licence projects that monetise cloud hosting rights. Feature-gating is more granular, enabling you to pay only for what you unlock, but it also requires disciplined role design and change control. Expect stronger clauses around AI training data, telemetry collection, and security posture – make sure your legal and security teams review those specifics, not just price.
There’s no single “best” licence – only the best match to how your teams work. Stable workloads on fixed endpoints often favour perpetual or device-based models. Dynamic, collaborative apps shine on subscription. Variable, API-driven services align with usage-based pricing. Open source lowers barrier to entry, but it asks for thoughtful governance.
Treat licensing like architecture: document assumptions, measure reality, and adjust. With the right mix – and the right operational tooling – you can keep costs predictable, audits painless, and your roadmap unblocked while staying fully compliant with software licence types in 2025.
