Web application
Web applications from €2,100. A custom solution makes sense the moment ordinary software is not enough — for example for your own calculator, a configurator, a client area or an app wired into your systems. It runs in the browser, no install needed.
What is included
- Process analysis and feature design — what the app must do and what it must not
- Screen and user-flow design
- Frontend and backend development including the database
- User accounts, roles and permissions
- Integration with external services over APIs where needed
- Testing and deployment to production
- Handover of the code and documentation — the project stays yours
- Training and support after launch
What costs extra
- Design to your brief beyond a functional UI (from €625)
- Payment gateway and invoicing (from €425)
- Further features and extensions after launch, depending on scope
- Regular maintenance and post-launch support — from €65/month Any service can be extended with regular maintenance: updates, backups, availability monitoring and small changes to content or features.
Who this suits
For companies that have their own process, product or service and need software built exactly around it. Typically a calculator, a configurator, a booking system or a client area.
Frequently asked questions
Questions about “Web application”
Why start with a web application rather than mobile?
A web application tends to be cheaper and faster for validating an idea. It works on a computer and a phone without installation. If it turns out users need a native app, I handle that as a separate service — see mobile application.
How much does a simple calculator or configurator cost?
A smaller tool such as a price calculator or a configurator sits in the lower part of the range, usually €625–1,700 depending on the complexity of the calculation and the systems it connects to. The full price from €2,100 applies to an application with accounts, a database and an admin area.
Does the app have an admin area where I can manage content?
Yes, if you need one. What you will manage yourselves — texts, price lists, orders or content for users — is part of the design, and the admin area is built around that. Its scope affects the final price.
Who owns the resulting code?
You do. Once paid, you get the code and all the access credentials and you are not dependent on me — anyone can carry the application on. I offer long-term maintenance, but it is an option, not a condition.
