Cash management is both a method and a theory.-As a method, it aims to manage liquid assets in companies and public bodies, whether in cash or in bank.- As a theory, it aims to explain the contours of short-term financial management. The aim of this book is to provide you with the essential Cash Management tools you need to tackle Modern Finance with confidence. No special financial background is required to understand this book. It is both a modest and interesting work.Modest because we have borrowed most of the ideas developed from a body of knowledge common to financiers. Interesting because the book acts as an intermediary between this body of knowledge and the reader. Its clear presentation, peppered with diagrams and tables, makes it easy to learn and assimilate the broad outlines of the subject. The book is divided into two (2) parts: Gestion de Trésorerie de l'Entreprise (F. Privée) and Gestion de Trésorerie des organismes publics (Finances Publiques). All these parts arecovered in 17 chapters, making this document a reference in the field.
