Clear answers to frequently asked questions.
How much does it cost to build software?
This depends on scope, complexity and lead time. A first working version is usually a process of a few weeks with a fixed monthly capacity. A website starts at 500 euros. After a non-binding conversation, you almost always have a concrete assessment within a week, including what you can’t build. See sample paths and build up your quote.Which service fits my needs?
Often they overlap. A customer portal is also a web application, and replacing Excel is a form of custom software. Choose the page closest to your question; in the first conversation we make what is really needed together.Do you build mobile apps?
We build web applications that work on laptop, tablet and phone. A loose app in the App Store is negotiable, but in practice, a good web application is usually faster ready and cheaper in maintenance.What’s the difference to your Microsoft 365 branch?
