CRM as an interface between people and technology

Numerous interfaces and automated data transfer make it easy to integrate your dealership's existing system landscape and additional third-party systems into our CRM software. In this way, isolated applications and media discontinuities can be avoided. The CRM software itself makes cross-departmental information available centrally. In this way, you avoid redundant double data entry and benefit from the bidirectional connection to specified vehicle manufacturer systems.
