Custom software development: process, cost and examples
10 min read
by Marcel, Senior software engineer
Having custom software built means this with us: first a free initial call, then a concept with a fixed-price frame, then a usable pilot module — and only after that the rollout. A clearly scoped first step starts at €3,900, an end-to-end complete solution at €11,900, and further development we bill at €79/h. The source code belongs to you in the end. That answer is the core — on this page you get the how, the what for and the why in detail.
The short version
- How it works: Free initial call → concept with a fixed-price frame → usable pilot module → staged rollout.
- Cost: A scoped pilot from €3,900, an end-to-end solution from €11,900, further development at €79/h.
- The code is yours: You get the source code with no vendor lock-in and no license rent.
- Low risk: Start with the one module that gives you the most, then expand step by step.
If you're reading this article, you've probably already settled the "whether". Now it's about the practical questions: how does a project like this actually run? What does it really cost? And how do I tell that I'm not walking into an expensive dead end? That's what this is about — honestly, without buzzwords and drawn from our actual projects.
Who custom software pays off for — and who it doesn't
Let's start honestly, because it saves you real money: not everyone needs custom software. If an off-the-shelf solution covers 90 percent of your requirements and the missing 10 percent don't slow you down daily, we'll point you to standard software — and we earn nothing from that recommendation. We've broken down this trade-off in detail in Off-the-shelf or custom software.
Custom software pays off precisely when one of these points applies to you:
- Your processes are your competitive advantage. You do something differently from the rest of the industry — and no off-the-shelf software captures that.
- The missing 20 percent costs you time every day. A standard solution covers a lot, but that one special case forces you into workarounds, duplicate upkeep and manual work.
- You're juggling Excel and isolated tools that don't talk to each other. Data gets entered multiple times, and nobody knows which version is right.
- You're paying yourself poor on subscription licenses without ever owning the software.
If you recognize yourself here, the next question isn't "is this possible?" but "is the effort worth it?". And that can be worked out cleanly.
Typical use cases from our projects
"Custom software" sounds abstract. In practice it's usually very concrete, down-to-earth applications. Four patterns come up again and again:
Replacing Excel. The classic. At some point a spreadsheet has become the company's unofficial operating system — and now it's creaking at every seam. We map the process into a real application where everyone works on the same state at the same time. When exactly the switch is due, you can read in Replacing Excel: time for your own software.
Internal tools. Order management, production planning, shift schedules, quote calculation — software that mirrors exactly your process instead of forcing it into someone else's corset. Tools like this often save the most time, because they're in use every day.
Customer portals. A protected area where your customers can look up orders, documents, tickets or their project status themselves — around the clock, without anyone having to pick up the phone at your end. That takes load off your team and looks professional at the same time.
Automation. Recurring manual steps someone does by hand today: moving data from A to B, copying reports together, generating invoices, sending reminders. Software does that in the background — error-free and without costing anyone their nerves.
Top tip
For one week, write down which task annoys you most or takes the longest. That's exactly where we start — not with the do-everything system, but with the one process that gives you noticeable time back immediately.
How it works: custom software development in four steps
The biggest reason software projects fail expensively is a wrong start: everything at once, a thick requirements document, a big quote — and six months later you notice half of it was built past the actual need. We deliberately do it differently. You'll find our full process on the how we work page too; here's the short version specifically for custom software.
Step 1: Free initial call
You tell us about your project, your processes and what annoys you today. We listen, ask questions — and tell you honestly whether a custom solution is worth it at all or whether standard software would be the smarter choice. The call is non-binding and costs nothing. You leave with a clear assessment, not a contract.
Step 2: Concept and a transparent quote
If it's a fit, we take a closer look at your process and turn it into a concept: what do we build first, what can wait, where are the special cases lurking? Out of that comes a traceable quote with a clear cost frame. You know where you stand up front — no surprises on the final invoice.
Step 3: Pilot module
Now we don't build the whole system, but exactly the one module that gives you the most — for example replacing your central Excel solution. After a few weeks you have something real in hand that you use day to day. You see how we work, and we get to know your reality. If it turns out something needs to run differently, we correct it early — not months later.
Step 4: Expansion in stages
Once the pilot module is running and delivering the expected value, we expand step by step: further modules, user roles, interfaces to your inventory or accounting system. Each stage is useful on its own and you decide anew after each step how it continues. That way the software grows with your company — without you ever losing control over budget and direction.
How long does development take?
The second most common question after price. The honest answer: it depends on scope — but because we work in stages, you never wait six months for the first result. As a rough orientation from our projects:
- Pilot module: after the concept, it's usually two to six weeks until you can test a first usable version in daily operation.
- Complete solution: depending on the number of modules and interfaces, expect a few months — but spread across stages that go live individually, rather than one big cutover date.
- Further development: runs continuously. We implement new features as needed, without operations having to stand still for it.
More important than the raw duration is the cadence: because each stage is useful on its own and goes into operation, value starts with the first building block — not only once everything is done. What you need for this is manageable: one or two contacts on your side who really know the process, and the willingness to answer the odd follow-up question. You don't need to bring a fully written requirements document — we work that out together.
What if the requirements change?
They will change — and that's completely normal. That's exactly why we don't believe in rigid mega-contracts that turn every deviation into an expensive dispute. As soon as you're working with the pilot module day to day, new ideas inevitably come up and you notice what really matters. Our approach absorbs that: after each stage we look together at what brings the most value next, and reprioritize. You pay for what gets built — not for a plan that's already outdated after two weeks.
What does it cost? The prices at a glance
There's no flat price "per software" — custom software is too individual for that. What we can give you are honest entry-level prices to orient yourself by:
| Service | Price | What for |
|---|---|---|
| Pilot project | from €3,900 | A clearly scoped first module, e.g. replacing Excel |
| Complete solution | from €11,900 | Several modules, roles and interfaces — your process end to end |
| Further development | €79/h | New features, taking over existing projects, refactoring |
| Maintenance | from €119/month | Updates, monitoring, bug fixes, a fixed point of contact |
What moves the price up or down in a specific case — feature scope, interfaces, user roles, data migration — we've taken apart in detail in What does custom software cost?. And if you want to play with numbers right away, the package configurator on our pricing page lets you put together, with no obligation, the range your project moves in.
The more honest calculation is the counter-calculation anyway. Don't just ask what the software costs — ask what the current state costs you:
- time per year if one manual step eats just an hour a day — per person
- 250 hrs
- entry point for a usable pilot module that starts exactly here
- from €3,900
- ongoing license costs — the software is yours, no subscription
- €0
Software that automates a manual process often pays for itself faster than you'd think.
"The code belongs to you": why that's decisive
It sounds like a technical footnote but it's one of the most important points of all: with us you get the source code, and you're not dependent on us. We deliberately build without hidden dependencies and without vendor lock-in.
You only notice why that matters so much when it's missing. Many providers build software so that you have to come back for every little thing — or worse: so that you start from zero if you switch. When the code belongs to you, the opposite is true:
- You can have the software developed further later by your own team or a different provider.
- You don't pay rent for something you should actually own.
- You can't be held over a barrel when a provider raises prices or discontinues support.
So that this doesn't stay an empty promise, we work cleanly, with documentation and clear conventions. A year from now, someone can still understand what the code does. That sustainability is the difference between "it runs for now" and "it still runs in five years".
Minimize risk: start small instead of failing big
The most expensive mistake with custom software is the big bang: develop into the blue for months, everything at once, and in the end it doesn't fit. That's exactly why the pilot module isn't a marketing trick but real risk reduction.
If you start small, your exposure stays manageable. You initially invest only in the one building block that gives you the most, see a result early and decide based on real experience whether and how to continue. If it turns out a requirement was meant differently, we correct it after a few weeks — not after six months and half the budget.
This step-by-step logic runs through everything we do: listen first, then a transparent quote, then develop in manageable stages. You stay in control at all times — over the direction and over the budget. If you want to go deeper into what's possible with tailored software, our custom software service page has the full overview.
Bottom line: how to get to your own software safely
Having custom software built isn't a leap into the unknown if you go about it the right way: honestly check whether it's worth it at all, start with a clearly scoped pilot module, expand in stages — and keep the code in your hands throughout. That keeps the risk small and the benefit noticeable from the start.

Frequently asked questions
What does it cost to have custom software developed?
A clearly scoped pilot module starts from €3,900, an end-to-end complete solution with several modules, roles and interfaces from €11,900. Further development we bill at €79/h, ongoing maintenance costs from €119/month. There’s no flat price per software — feature scope, interfaces, user roles and data migration decide where you land.
How long does custom software development take?
After the concept it’s usually two to six weeks until you can test a first usable pilot module in daily operation. A complete solution takes a few months, but spread across stages that go live individually instead of one big cutover date. So you get value from the first building block, not only when everything is finished.
Do I get the source code and own the software?
Yes. You get the source code, you’re not dependent on us, and there are no ongoing license costs. We deliberately build without hidden dependencies and without vendor lock-in, so you could have the software developed further by your own team or another provider later. To make that real and not an empty promise, we work with documentation and clear conventions.
What happens if my requirements change during the project?
They will change — that’s completely normal. As soon as you use the pilot module day to day, you notice what really matters. That’s why we don’t work with rigid mega-contracts: after each stage we look together at what brings the most value next and reprioritize. You pay for what gets built, not for a plan that was outdated after two weeks.
