Custom software development

The spreadsheet that keeps
your business running.

Almost every company has one: a spreadsheet, a folder of forms or a tool meant for something else, that the whole process now depends on. It works, until someone is ill, a formula breaks or nobody remembers why column H is the way it is. At that point custom software is cheaper than muddling on.

Sound familiar

When custom pays for itself.

01

The same data, entered three times

From quote to planning to invoice, by hand every time. Every retype is a chance of an error you only spot weeks later.

02

The standard package does not fit

You pay for eighty features, use six, and the very part that makes your business unique is not in there.

03

The process lives in someone's head

One person knows how it works. If they go on holiday it stalls, and nobody dares change anything.

04

Reporting costs a day a month

Pulling figures out of three systems, pasting, checking. While the answer could be on a screen every morning.

05

Growth means more people

Every new customer costs as much manual work as the last. That is buying revenue growth with salary costs.

06

The spreadsheet has become a risk

No permissions, no history, no backup anyone has ever restored. One wrong sort and the source of truth is gone.

How it works

The process first, the software after.

01

Get the real process

Who does what, where it stalls and what that costs per week today. Not how it is supposed to go, but how it goes. Part of the wish list usually falls away right here.

02

Discovery with a prototype

Five working days in which the core screens become clickable and the scope goes on paper, with a fixed price for the build. If building turns out not to be the smartest step, you hear that too.

03

Build in short cycles

A working version in a preview environment every week or two. You use it before it is finished, so wrong assumptions surface early.

04

Roll out and hand over

A pilot first, then everyone. With documentation, tests on the paths where money or data passes through, and the code in your repository.

What you end up with
  • One system instead of three places
  • Login with roles and permissions per user
  • Integrations with your accounting, CRM or planning
  • Reporting that is simply there
  • Repository and hosting in your name

The price depends on how much process is in it and how many systems have to hang off it. After a half-hour call you get an indication, and after Discovery a fixed number.

Frequently asked questions
What does custom software cost?
You get one fixed number for an agreed scope, so no reckoning afterwards. What that number is depends on the size of the process and the number of integrations. After a short call you get an indication; after Discovery the price is fixed.
Why not just use an existing package?
Often that is wiser, and then I say so. Custom is worth it when the process is a difference against your competitors, or when you are currently bending over backwards to make a package do what it was never meant for.
How long does it take?
A first usable version is usually four to six weeks. Bigger systems grow on from there in cycles, so you have value along the way instead of only at the end.
Can it connect to our current systems?
Usually yes, through your package's API. If there is none, we look at an export or a periodic sync. This is the first thing I check, because it often decides more of the build time than the screens do.
What if we want to maintain it ourselves later?
Everything sits in your repository, in standard Next.js and TypeScript, with migrations and documentation. Your own team or another developer can take it over without me.
We already built something with an AI tool. Does that count?
Yes, and it saves time, because you tried out what you want instead of writing it down. I first judge what is usable and what is missing below the waterline. There is a separate track for that: vibecode to production.
Let's build

Tell me what you
want to build.

A half-hour call. You get an honest answer about what it costs, how long it takes and whether building it is smart at all.
