This book demonstrates how founders can gradually obtain meaningful leadership and decision-making information, taking into account the specific characteristics of young companies. Systematic controlling with planning, management, and monitoring is often more of an exception than the rule in this context. What initially seems manageable can soon become overwhelming for many founders. However, the use of the right controlling tools and regular engagement with key performance indicators can help identify opportunities and risks in a timely manner, and above all, prevent failure due to avoidable mistakes. Moreover, when discussions with banks and investors arise, a solid reporting system becomes essential. Numerous practical tips, examples, and overviews, along with the fundamental principles of accounting, make it possible for newcomers to get started. Helpful.
