Custom software development
Sometimes no off-the-shelf package fits the way you work. Then I build custom software: tools, dashboards and automations that do exactly what your process needs.
No features you pay for and never use. Just a solution that connects to your existing systems and grows with you.

Software that adapts to you
Standard software often forces you to bend your process around it. Custom flips that: the technology adapts to your way of working, not the other way around.
I connect the software to your existing systems and data, so everything works as one. You keep grip on what happens and only pay for what you actually use.

What I build for you
Custom tools
An application that solves that one process you're currently losing too much time on.
Dashboards
Your numbers and data clearly together, so you base decisions on facts.
Automations
Repetitive work that runs by itself: processing data, connecting systems, generating reports.
Integrations
Your website, CRM, webshop and other tools connected into one working whole.
Built in-house
Software I built for myself, and that pays for itself
Before I build software for you, I build it for myself. Two of my own products are live, and they save me subscriptions every month.
Store locator
StoreLo
Replaces a store locator subscription. Saves at least $10 a month, and more once you pass 100 locations.

I run my own webshops on Medusa, open-source commerce, instead of Shopify. No monthly plan and no extra fee on every sale: you only pay your payment provider, like €0.32 per iDEAL payment with Mollie. At €5,000 revenue a month that saves €25 to €128 a month compared to Shopify Basic.

Gerben HobelmanTechnical Specialist, Coverband ZUKOHow I approach it
We start small and concrete. First we look at which work costs you the most time or goes wrong most often. I build a solution for that which you can use right away.
Does it work? Then we expand. That way you never invest in a big system that turns out not to fit, but grow step by step with technology that has already proven itself.

Frequently asked questions
What does custom software development cost?
That depends on what you need. Because we start small and concrete, you quickly see whether it delivers what you hoped before you invest big. I provide a clear estimate upfront, with no surprises afterwards.
What if I want to change something later?
Custom software is meant to grow with you. Because I build and know it myself, I can extend or adapt it later when your business or process changes.
Does it work with the systems I already have?
Yes, that's often the whole point. I connect the software to your existing website, CRM or webshop, so your data comes together in one place and everything fits.
