Energy supply companies face the question of how to adapt their responsiveness to volatile markets using appropriate business management tools and gain competitive advantages. A well-thought-out sales strategy is essential for sustainable market positioning. The foundation for this, in addition to the commitment of the sales staff, is a precise understanding of revenue, cost, and sales-related factors. In particular, municipal utilities must confront competition with limited resources and restricted options. This book illustrates the extent to which sales controlling is implemented among energy suppliers and which tools are particularly suitable for municipal utilities with fewer than 50,000 customers to gain a meaningful overview of the sales situation. The presented key figure system enables the analysis of market-related information.
