05FAQ

Good questions. Clear answers.

Can’t find your question? Write to us.

How much does custom software cost?

That depends on the scope, the features and the interfaces required. After an initial conversation, you’ll receive a transparent quote from us – split into project phases if you like.

How long does a project take?

A website is often online within a few weeks; larger apps or business software are built in several iterations. We set a realistic schedule together in the concept.

Do you also take over existing projects?

Yes. We analyze existing software, fix bugs, modernize outdated technology and develop it further where it counts.

Do you look after the software after launch?

Yes. If you wish, we take care of hosting, maintenance, security updates and further development – so your solution keeps running reliably.

Who do you work for?

For businesses of every size – from trade businesses and mid-sized companies to start-ups. What matters is that together we find a clear solution for your task.
