The document discusses key account selling and management. It defines key accounts as the top 20% of customers that provide 80% of profits, based on the 80/20 principle. The benefits of key account programs include economies of scale, understanding customer goals, and sustainable sales. Key criteria for selecting key accounts include sales volume, profits, financial stability, and coherence with company strategy. The document also cautions that key account programs require sufficient benefits and should not rely too heavily on just a few large customers.
