Lothar Stanka, Head of Sales Business Clients, Süwag Energie AG: 
"The liberalisation of the energy market has had significant consequences in the area of sales. Apart from the required structural adaptation of internal processes, the primary objective here is the systematic training, support and sales management of our approximately 40 energy managers. In this, we have relied on the know-how of the entire Wirkung Plus team since 2009. Clear structures, a coherent overall concept and the high degree of personal commitment demonstrated have won our confidence in this respect."
