Analysis of the legacy system settlement procedure

The application being analyzed is a document entry system used both to record inbound documents (invoices from providers) and create outbound documents (monthly advance payments and annual statements). In the past, the statements were only created on the basis of inbound documents. In future, a well-developed tariff system is to be used to form the basis for more complex settlements. These settlements are a prerequisite for new business models that are already possible when designing contracts.
