“Gupta and Lehmann have brilliantly brought together the customer and financial views of marketing. Astonishingly, many companies struggle to recall that cash comes from customers and that marketing is the sourcing and harvesting of that cash. Gupta and Lehmann provide the theory and practice for marketers and CFOs alike. Bravo!”

“This book proves the adage that nothing is as practical as a good theory. The concept of lifetime value of a customer is presented in a straightforward and very practical way that will be extremely useful to marketers who are charged with improving financial accountability and managing ROI. It gives the reader enough information to get started with readily available data to understand how to think about and how to take action on customer management issues. The notion that it's better to be 'vaguely right, than precisely wrong' is just the right thing for companies that know they need to move on these issues but are struggling to get results. I strongly recommend this book for marketers who want to get more effective at customer management. The methods introduced in this book are important building blocks for a long-term testing and learning process to improve business performance.”

“Gupta and Lehmann have written a rigorous, yet practical, guide to a complex and important area of timely importance to all senior executives; namely, how to manage customers profitably. This book shows effectively that the responsibility for managing customers is a cross-enterprise responsibility.”

“For all those managers discussing how they would use client lifetime value...if they only had the information...this book answers that question and more. The text is thoughtful and explicit on how you can actually produce an effective valuation—and without all the detailed information that has traditionally been required. The authors deliver a researched formula and methodology and also demonstrate how best to manage this information and relevant analyses for profitable growth with improved new metrics. And they provide practical examples and case studies for decision-making using this new information. Managing Customers as Investments offers the roadmap and toolkit to shorten the trip to greater customer management insight.”

“Managing Customers as Investments provides a comprehensive, accessible and practical guide to understanding and managing customers in today's complex marketing environment. It offers managers in-depth insight into calculating customer lifetime value (CLV) and using CLV to improve a company's bottom line. Further, it provides practical tools such as the 'two sides of customer value' framework that managers can actually use to identify priority customers and a step-by-step approach to what it takes to become a customer-centric organization.”
