What Does It Cost to Have Your Own SaaS or Web App Built?

The honest answer up front: there is no flat rate. A web app can cost 6,000 euros or 250,000 euros - and both can be correct for the case at hand. The difference comes down not to luck but to scope. So you're not left fumbling in the dark, here we break down the real cost factors and name realistic ranges, rather than selling you a number you'd like to hear.

Why the range is so wide

A SaaS is not an off-the-shelf product but the sum of many decisions. Each of those decisions shifts the price - sometimes by hundreds, sometimes by tens of thousands of euros. The biggest drivers:

MVP instead of full product: the single biggest lever

The classic mistake of many first-time founders is wanting to build everything from day one. That burns budget on features nobody ends up using. The smarter approach is an MVP (Minimum Viable Product): the smallest version that solves a real problem and that wins you your first users or first payments.

An MVP typically covers the one core workflow, login and simple data management - nothing more. Everything else comes later, once real user feedback shows where the product genuinely needs to go. That doesn't just save money, it also stops you from investing weeks in features you'll only delete again afterwards.

A well-thought-out MVP starts with us in the region of around 6,000 euros. A full-fledged SaaS or tech build with user teams, billing, multiple modules and interfaces realistically lands between 6,000 and 25,000 euros, depending on depth. If you're after a pure content website rather than an app, you're well below that: a one-pager runs 2,000-3,000 euros, a multi-page site with a content management system 4,500-8,000 euros.

What we can speak to here

When we talk about SaaS costs, we're not speaking from theory. We run seven of our own brands live in production - among them an accessibility scanner, a cosmetics product portal with around 177,000 products, a vehicle deal radar, a marine SaaS and an industrial marketplace. We built, operated, scaled and in some cases also slimmed down every one of these applications ourselves. So we know not only the build costs but also the running costs - and it's exactly those that most people underestimate.

The costs nobody thinks about

The development price is only the first invoice. A SaaS keeps living, and that creates ongoing expenses:

Budget a monthly line item for operations rather than ignoring it. An app that nobody maintains turns into a liability within one to two years.

When you don't need custom development at all

This too is part of the honest answer: not every idea needs a bespoke SaaS. If an existing tool or a combination of standard building blocks covers your needs, building your own is often the more expensive and slower route. Only when your workflow is genuinely unique, when you need data sovereignty, or when the product itself is your business model does building your own pay off. Before you put money into code, it's worth asking the sober question of whether there's already a ready-made path.

Fixed price instead of the hourly lottery

Hourly rates sound flexible, but for you they're an incalculable risk - you pay for every delay. That's why we work with clearly defined fixed-price tiers: you know in advance what you get and what it costs. That requires the scope to be cleanly defined, and it's precisely this first clarification step that is the best investment against nasty surprises.

Need a website, a tool or a SaaS of your own?

We build it at a fixed price — by the team that runs seven of its own brands live. Clear scope, clear price, clear timeline.
