Subscription, perpetual, usage-based, per seat, per core, per server—the software licensing landscape has become more complex in recent years. And that complexity costs organisations money: choosing the wrong model means paying structurally too much.
The three main models
Subscription
The most common model in modern SaaS. You pay a recurring fee, monthly or annually, for access to the software. Advantages: always the latest version, low entry costs, flexibly scalable. Disadvantages: no ownership rights, structurally higher costs in the long term, and automatic price increases at renewal.
Perpetual
You buy a licence once and own it forever. You pay annually for support and maintenance (typically 15–22% of the purchase price). Advantages: ownership rights, predictable costs, no vendor lock-in through subscriptions. Disadvantages: higher initial investment, no entitlement to new versions without an upgrade.
Usage-based
You pay based on actual usage: number of API calls, gigabytes of data stored, active users per month. Advantages: costs follow usage, ideal for variable workloads. Disadvantages: unpredictable invoices during peak times, difficult to budget.
Hybrid models
Many vendors combine models. VMware, for example, offers a subscription per core bundle. Palo Alto combines hardware (perpetual) with software subscriptions. Atlassian works with tiered pricing per user band. These hybrid models make direct comparison to alternatives difficult, which benefits the vendor.
How to choose the right model?
The choice depends on three factors: expected duration of use, stability of use, and the importance of ownership rights. Always have a Total Cost of Ownership analysis done over at least three years — only then does it become clear which model is truly more cost-effective.
Frequently Asked Questions
The most asked questions about this topic.
Which is more cost-effective: subscription or perpetual?
Subscription always gives you the latest version and lower initial costs, but higher ongoing expenses. Perpetual has higher upfront costs but you own the licence. After three to five years, perpetual is usually cheaper, provided support is purchased separately.
When do you choose usage-based pricing?
Usage-based is ideal if usage varies greatly. You only pay for what you use, but costs are hard to predict. For stable usage, a fixed subscription or perpetual licence is often more economical.
How do I choose the right licensing model?
Always have the Total Cost of Ownership (TCO) calculated over at least three years, including support, upgrades and any exit costs. SoftVaro assists with this analysis and negotiates the best model for your situation.
