Sitara® is a comprehensive ERP and enterprise resource planning software from Hausmann Wynen. The company was founded in 1983 by Reinhard Hausmann and Hartmut Wynen in Monheim am Rhein. Initially, the focus was on the development of software for electrical engineering companies, but Hausmann Wynen quickly specialized in the areas of building services and trade.
For more than three decades now, we have been facilitating the work processes of our customers and thus ensuring greater efficiency and profitability.
Thanks to our many years of experience and our extensive know-how, we have established ourselves as a manufacturer of industry software for electrical engineering and building services and are now one of the market leaders in the field.
