At the beginning OZ GmbH was the German subsidiary of the Switzerland-based consultancy and software company Organisation Zoller AG.


The Swiss company has been split in 1993. The German subsidiary has been dissolved. But the name has been stuck.

Today the name  OZ  is a synonym for

Organization solutions for the future“.


Our lisa products are always in the sense of complete solution as "Software and system", so that they meet these requirements in an outstanding manner.
