Reflection on the problem of financial management in organizations by businesspeople is becoming more important these days. The book, "Thinking about the Organization in Financial Management", is not intended to be a mere theoretical approach to the subject, but rather a set of proposals, the fruit of the authors' experience, which can be adopted and adapted by all those who see the challenges as a daily act towards greater efficiency in the work of managers and, consequently, an improvement in results to combat financial losses, high costs and company closures. When it is well applied and well controlled, it brings greater profitability, enabling the process of maximizing results by making it possible to analyse Liquidity, Indebtedness, Activity and Return ratios for the well-being of companies and families.
