You may have interest in this article I authored titled “Measuring and Managing Customer Profitability” for the Strategic Finance magazine published by the Institute of Management Accountants. Its message is that customers are the source of financial value to increase shareholder and owners’ value. But today customers view suppliers’ products and service-lines as commodities. Therefore suppliers must provide differentiated services to different customer segments. The sales volume of high demanding customers is not proportional to their profit level because they cause extra expenses from their suppliers. (I wrote the article related to my part time role as the IMA Executive in Residence now in my 4th year term. The www.imanet.org has 85,000 members in 140 countries.)
