Questions

Frequently asked.

What does a custom web application cost?

An internal tool starts at about €2,500, a web app or a customer portal at about €6,000. After the initial assessment you receive a binding fixed-price quote.

How long does development take?

An internal tool is usually ready in 3 to 6 weeks, a larger web app in 2 to 3 months.

Where is the application hosted?

On a server in Germany under your own account, for example at Hetzner. If I have access to personal data in operation, we sign a data processing agreement.

Do you work with AI?

Yes, as a tool. AI speeds up routine work, but responsibility stays with me: every line is reviewed and tested. You benefit through shorter timelines and more favourable fixed prices.
