FAQs

Frequently asked questions

A website informs, a portal interacts. Online portals map processes, enable logins, data exchange and self-services. They are directly connected to internal systems and serve as a central interface between companies and customers or partners.
Yes, we integrate ERP, CRM, PIM or document systems via standardized interfaces (REST or GraphQL APIs). This allows data to be managed centrally and synchronized in real time - without redundant processes or media disruptions.
Usability is at the heart of our development. We involve users in design and testing at an early stage, carry out feedback loops and continuously optimize navigation and interactions. The result is a portal that is actually used in everyday life.
We rely on proven authentication methods such as OAuth2 or SSO with Keycloak or Azure AD. Access controls, role models and encrypted communication are standard. Your data remains protected - even with cloud hosting.
The costs depend on the scope, functions and integration effort. After the introductory meeting, you will receive a transparent offer with a phase plan. Many projects start with an MVP in order to quickly make the first functions usable and build on them.
