The profit and loss account is an essential component of the annual financial statements and is indispensable for success control. With a professional, integrated driver-based P+L, the management receives an overview of the current financial situation of the company and thus a sound basis for corrective measures and essential decisions. Despite their central function, many companies still plan and report their profit and loss accounts in time-consuming and error-prone Excel processes. The financial department therefore often has to collect and process relevant data manually. STRATO was struggling with these problems until recently. A complex data source and the manual preparation of data in Excel made planning and reporting an enormously time-intensive and error-prone process. Particularly the planning of individual business drivers across different regions, product groups or cost centres, which formed the basis of the P+L, was very difficult due to its high complexity and interdependences. Subsequent adjustments resulted in a lot of manual work and it was virtually impossible to plan scenarios.
