Understanding customer level profitability implications of satisfaction programs

Achieving high level of customer satisfaction (CS) involves spending marketing resources in terms of money, managerial time, and focus. Consistent with the return on quality framework this paper aims to look at both the costs and benefits of a satisfaction program.

This paper reports the results of a longitudinal study of a beverage distributor. Two satisfaction surveys were conducted before and after the launch of the program. Profitability was calculated using activity based costing (ABC) principles. The link between changes in satisfaction and changes in profitability was analyzed.

It was found that as a result of the launch of satisfaction program CS increased significantly, but the weighted least square analysis of the relationship between CS and customer profitability (CP) shows that it does not necessarily result in higher customer profits. CS is found to be positively related to sales volume and gross profits at the customer level. However, a net profit measure of CP, derived after careful allocation of costs based on activities, shows a much more complex and non‐linear pattern of relationship.

The paper shows that there are several valuable lessons to be drawn from the study. First, the cost of increasing satisfaction could be substantial. A positive relationship between satisfaction and profitability, posited by most of the customer satisfaction literature, could reach its limit much sooner than generally believed. Second, allocating costs based on activities in serving the customers, and not merely on revenues is important since doing so results in a different and more complete profitability profile of customers, as is described in the sample. Finally, the complexities and non‐linearities in the CS‐CP link documented in this study imply that satisfaction improvement efforts (and dollars) should be directed towards larger customers and customers who are already relatively highly satisfied.
