Direct Guidance

Frequently Asked Questions

Key considerations when commissioning custom software.

Why build a custom web application instead of buying off-the-shelf SaaS?

Off-the-shelf software forces your team to bend its workflows around rigid templates and pay escalating monthly per-user licensing fees forever. A custom web application is built strictly to your operational requirements, provides full intellectual property ownership, and scales without licensing penalties.

Who owns the source code and database once the project is finished?

Your organization owns 100% of the custom source code, documentation, and underlying database architectures. We hand over clean Git repositories upon project completion.

How do you ensure the security of customer and company data?

All web applications are engineered according to OWASP Top 10 standards: encrypted database connections, parameterized SQL queries preventing injection, FIDO2 multi-factor authentication, and automated audit logging.
