Rudolf Sulzer founded information system and software provider Infosystem AG in Zurich in 1968.
Our work centers on maintaining a direct dialog with our customers. Together, we establish their requirements and develop the ideal solution. We do not sell software, we provide solutions. Our internally developed performis® ERP system is used as the basis for comprehensive customer solutions in a wide variety of projects. The customer receives a tailored solution using as much standard software as possible and as much specially developed software as necessary. In this way, customer projects benefit from a quick and reliable solution at a good price.
