CASH FLOWS IN AND CASH FLOWS OUT OF EVERY business. Whatever your job, you contribute to both flows: You are a resource that costs dollars,
and you use or somehow influence the use of other resources that cost dollars. At the same time, your actions have a direct or indirect effect on cash coming into the business.

But what are the key factors that drive that two-way flow? If you can identify those factors in terms of your company’s basic operations, you will gain a powerful tool for growing your business and ensuring that the cash flowing in exceeds the cash flowing out.

This book aims to help you do exactly that. It focuses on what I call cash drivers, seven things that control virtually all cash flow for virtually every business almost all of the time. They are: sales growth; gross margins; selling, general and administrative expense (SG&A); accounts receivable;
accounts payable; inventory; and capital expenditures (Capex). This book will show you how to understand, measure and analyze your business, as a whole and in its individual parts, in terms of these cash drivers.
