Custom software
Custom software that fits the way you work.
Off-the-shelf software rarely fits exactly. I build web apps, internal tools and backends around how your business really works, from a custom CRM or admin panel to a complete backend that scales.
What you get
Internal tools & dashboards
Software that takes work off your team. From planning and inventory to a custom CRM or admin panel.
Web apps & platforms
A platform or SaaS product of your own, from idea to live. Think CareerMate and Schakel.
Integrations & backends
Getting systems that do not know each other to talk nicely together, with solid backends that scale.
Direct contact
You work directly with the developer who builds it. Contact via WhatsApp, also after launch.
Real work
What this looks like in practice.
Floravert
An internal web app that merges the stock lists of around 350 growers into one sales list. AI recognises the structure of each list, a custom script normalises the data and it exports to Excel in one click. Saves hours of manual work every week.
Platform · backendTreinGeldTerug
The complete backend for a service that automatically reclaims money for NS train delays. From detecting delays and filing claims to handling and invoicing, it all runs fully automated on Cloudflare.
treingeldterug.nl ↗ WordPress · pricing pluginEuropaSign
A custom WordPress plugin that pulls all price calculations out of the order forms. All the logic now lives in one manageable admin panel; the form is purely the interface and the price rolls out live.

Grab a coffee
We discuss your wishes and goals and look at examples you like together. No sales pitch, just a good conversation.
Design & build
I get to work. You get unlimited revision rounds, so we keep refining until it is exactly right.
Launch & care
Your website goes live. I handle hosting and security updates for 10 euros a month, so you never have to worry about it.
Frequently asked questions
What does custom software cost?
That depends on what you need. After a short conversation you know where you stand: clear prices and no surprises afterwards.
Can you connect to systems I already use?
Yes. For example, I have built Shopify apps that sync inventory and orders with Bol.com and push orders into Moneybird invoices.
Where does the software run?
We settle that up front. Some of my projects run on Cloudflare, such as the complete backend of TreinGeldTerug.
Do you keep working on my software after delivery?
Yes. You keep direct contact via WhatsApp, also after launch.
Who builds it?
Dennis, the founder of Klappe Development in Enschede. Since 2018 I have built websites, personally and without middle layers. I also build software and AI solutions.
