This book shows small and medium-sized enterprises how they can systematically assess and strengthen their financial performance, which is the economic core of their business. Just as core training is important for fitness enthusiasts, the same applies to companies: the greater the internal stability, the more attractive the external appearance. Through a solid rating test and clear metrics such as capital strength, debt, return, or risk reserves, SMEs can determine how liquid, creditworthy, and capable their business currently is, as well as uncover any hidden financial resources. A practical workbook for all decision-makers in SMEs who have always wanted to activate the full financial power of their company to achieve sustainable success. It includes numerous checklists, step-by-step guides, and specific tasks.
