Problem customers can cost your business lots of money, but quickly ejecting them may not be the best way to relieve the burden. Mittal, of Rice University, Sarkees, of Penn State, and Murshed, of Towson University, explore the ins and outs of customer divestment. Using real-world examples, the authors show how deciding to end a relationship with a customer segment or individual can increase profitability, improve employee morale, address capacity constraints, and bolster a business strategy. However, divestment also comes with potential downsides for various constituencies, including employees and remaining customers, both of whom may wonder whether they're next. In addition, ethical and legal consequences -- and the risk of bad publicity -- always loom. Before you rush to action, say the authors, walk through their five-part customer divestment framework. First, reassess the context of present customer relationships, looking beyond simple profitability. You may find that the most productive option is to educate customers rather than drop them. In some cases, if you renegotiate the value proposition with them, both of you will win. In other instances, you'll want to migrate customers to other subsidiaries or providers, as long as the move is undertaken -- and perceived to be conducted -- in good faith. If it becomes necessary to terminate a customer relationship, use a direct, interpersonal approach. No business can afford to squander its customer base, so divestment should not be boiled down to determining merely who is profitable and who is not -- the strategic consequences are too weighty. In the end, the decision about whether to divest might prove to be the toughest customer of all.
