Application Areas

When does a desktop app make sense vs. web?

Desktop when: offline capability required, large data volumes, hardware integration (scanners, printers), maximum performance. Web when: multi-location access, simple deployment.

Can you connect to existing databases?

Yes, we connect to SQL Server, Oracle, PostgreSQL, Access and more. Also legacy databases that have been in use for decades. Data migration and synchronization included.

Costs & Maintenance

What does a desktop application cost?

Simple tools from €10,000, business applications €30,000-100,000, complex enterprise software €100,000+. After analysis, you receive a transparent estimate.

How does maintenance work?

Updates via installer or auto-update. We offer maintenance contracts for bug fixes, security updates and enhancements. Many customers we support for over 15 years.

Modernization & Future

Can you modernize old Delphi/VB applications?

Yes, that is one of our specialties. Stepwise migration to modern platforms, UI refresh, or complete rewrite – depending on what makes sense. We evaluate honestly.

Does desktop development still have a future?

Absolutely. For many use cases, desktop apps are still optimal: industry, healthcare, finance. The combination of desktop and cloud (hybrid) is often the best solution.
