What does custom software cost — and why a subscription is often smarter

An honest look at where the cost of custom software really sits, and why a hosted subscription with maintenance included often works out cheaper than a one-off build.

“What does custom software cost?” is almost always the first question. The honest answer: it depends on what you build — but the biggest cost is almost never the building itself. This article explains where the money actually goes, and why a subscription often works out cheaper than a one-off project.

Where the cost really sits

Custom software has three cost areas — and two of them never stop:

Development. The building: analysis, design, programming, testing. This is one-off, but it isn’t finished the moment the software “works” — the first version is rarely the last.
Hosting. The software has to run somewhere: servers, a database, a domain, security. That costs money for as long as the software lives, not once.
Maintenance. Browsers change, integrations shift, a bug surfaces, a law demands a tweak. Software that isn’t maintained degrades on its own.

The trap with “having it built once” is that you pay only the first area and think you’re done. Hosting and maintenance still arrive afterwards — often as separate bills at moments you don’t choose.

A one-off build versus a subscription

With a one-off build project you pay a large amount up front for development. You then own the code, but also everything that comes after: arranging hosting, planning updates, tracking down a developer when something breaks. For a large organisation with its own IT department that can be fine. For most business owners it’s a hidden burden.

With a subscription (software-as-a-service) you pay a fixed amount per month. Development, hosting and maintenance sit in one price. There’s no large investment up front, and keeping it running is no longer your problem. If something breaks, it gets fixed without a separate quote.

What “included” actually means

The word included is where the difference sits. With a subscription it means, concretely:

The software runs, is backed up and secured — without you managing a server.
Updates and improvements are added automatically.
A bug is not an extra invoice, but part of the deal.
As your business grows, the software grows with it without starting over.

You’re not renting a lump of code; you’re renting a working system that keeps working.

When a one-off build does make sense

Fair is fair: sometimes a one-off project is the right call. If you know exactly what you need, it rarely changes, and you have the people in-house to manage it, then ownership can be cheaper in the long run. The question isn’t “subscription or not”, but: who keeps this running in five years, and what does that cost?

For most companies without an in-house developer, the answer is a subscription — precisely because the costs after delivery are the largest and the least predictable.

How we work it out

We work with one monthly amount that covers development, hosting, maintenance and management together. No large investment up front, no separate bills when something needs doing. What that amount is in your case depends on what we build and how hard it runs — you hear it after the intake, not from a table on a website. How we get from idea to working software, and what you do and don’t have to do yourself, is on our approach.

Custom software doesn’t have to be a leap in the dark. When the costs are predictable and the maintenance isn’t your worry, it simply becomes a fixed line item — like your accounting or your phone plan.
