Comparison
Subscription or perpetual licence: what each one buys
In one case you rent access and receive improvements; in the other you buy a version and keep it, for better and for worse.
Subscription pricing means you pay monthly or annually for the right to use the program, and the price usually includes updates, security fixes and basic support. On the day you stop paying, access closes and you are left with whatever data you exported, assuming you took care to export it. A perpetual licence means you pay once for a specific version and may use it as long as you like; updates, however, arrive separately through an optional maintenance contract, and within a few years your version stops receiving fixes and stops running on current operating systems. The choice is not made on accounting preference but on three factors: how fast the domain covered by that software changes, how much it matters to you that the program runs on infrastructure you control, and how large the exit costs are if you want to change supplier four years from now. Anyone comparing only the first invoice reaches the wrong conclusion almost every time.

Key takeaways
What the subscription buys you
You get in quickly with small financial effort, and receive new versions constantly without upgrade projects. If the software does not suit you, you leave after a few months with limited loss — a genuine advantage when you are not yet certain of the need.
What the perpetual licence buys you
The cost stops somewhere. Once the purchase is amortised, the program keeps running with no recurring payment, you can sit on your own infrastructure, and nobody's commercial decision determines whether your application opens in the morning.
Where the calculation flips
At a small number of users, the subscription stays cheaper for years on end. As the team grows, the monthly cost per head multiplies linearly, and the licence paid once starts to look steadily better inside a multi-year budget.
The risk each model conceals
The subscription exposes you to price rises and to feature changes you do not control. The perpetual licence exposes you to ageing: without a maintenance contract, within a few years you hold a program nobody can secure any more.
The five-year calculation, done properly
Put both columns on paper over sixty months. On the subscription side, add the list price multiplied by the number of users, the expected growth of the team, the extra modules you will switch on, and the cost of the initial data import. On the licence side, add the purchase, the annual maintenance contract if you take it, the server it runs on, the administration of that server, and a reserve for the major upgrade that will arrive sooner or later. Only then do you compare the totals, rather than the numbers on the front page of the quote.
Add one more line that suppliers never include: the cost of leaving. Ask in writing, before signing, in what format you can export your data, how long it stays available after the contract ends, and whether the export includes the full history rather than only the current position. A cheap subscription you cannot get your data out of is more expensive than a licence twice the price that you can walk away from in an orderly fashion.
When you do not need us in this conversation
For ordinary office tools — email, shared documents, document signing, basic bookkeeping — the subscription is the obvious answer and there is no point paying anyone to confirm it. Domains that change frequently for regulatory reasons are precisely the ones where you want somebody else handling the updates on your behalf.
Call us when the software in question is tied directly to the process that earns your money, and when the number of users makes the recurring cost genuinely material. That is when we put a third option on the table, one subscription vendors never mention: an application of your own, paid for once, whose source code belongs to you. It is not the right answer everywhere, but it deserves calculating before you sign five years of rent.
Frequently asked questions
What happens to my data if I stop the subscription?
It depends strictly on the contract. Serious vendors keep the data for a defined period and provide a complete export; others leave you with partial reports or formats that are hard to reuse. Check the clause before signing and test the export in the first month, while you still have room to react.
Does a perpetual licence really mean forever?
It means the right to use that version without a time limit, not the right to future versions. In practice, a program without updates becomes a security and compatibility problem within a few years, so budget either the annual maintenance or a planned replacement.
Can a subscription be covered by EU grant funding?
The treatment of recurring expenses differs between programmes and is read exclusively from the applicant's guide for the call you are applying to. Do not build a budget on practices you heard from other beneficiaries; check the wording in the official documentation and, where it is ambiguous, request written clarification from the managing authority.
How do I negotiate price increases on a subscription?
Ask upfront for a cap on the annual uplift and a price locked for the duration of a multi-year contract, in exchange for a longer commitment. Vendors frequently accept, but almost never propose it themselves, and the difference over five years can exceed the cost of an implementation.
