If you have a small number of customers that make up a large part of your revenue, these are key customers that deserve special attention. For companies with such customers, allocating a special unit and budget for key customer management will be both an economical and profitable move.
Key client management requires primarily experience, multiple foreign languages, stress management, effective communication skills and leadership qualities. Because key customers are difficult customers to recover if they are lost for the company. In this respect, spending company resources on the satisfaction of existing key customers rather than advertising to acquire new customers is a more advantageous choice in the long run.
