Due to the liberalization of the energy market the utilities sector faces new challenges. Not only the splitting between energy production and energy transport but also the offering of new products and competitive packages creates new business models and tasks. This also brings up the necessity to optimize the way of communication with the customer. The times when a simple colorless and emotionless bill was presented to the customer are over. Customers expect and demand personalized and well-organized documents. Companies realize that documents are one of the rare occasions to actually communicate with their customer. From this perspective it becomes clear that they are a perfect marketing tool to achieve customer satisfaction, inform about new products, activities and other topics which might be relevant for the customer.

Beyond this, the demand for splitting billing information based on different tariff models, and the possibility of having partner companies provide subservices (e.g. transport) makes the creation process of documents and the logic contained within them a demanding task.
