Key account management

What is key account management?

Key account management is serving a company's most valuable customers with dedicated people, plans and executive attention. Each key account gets a named owner, often a key account manager, plus access to specialists and senior leaders that other customers do not get. Malcolm McDonald and colleagues describe it as a natural development of customer focus and relationship marketing in business markets.

Why it matters to a revenue leader

In many services companies, a handful of customers carry a large share of revenue, and losing one hurts the year. Key account management puts the best people and executive time on protecting and growing those relationships. Gartner warns that choosing key accounts by size alone often disappoints, because strategic relevance and the customer's willingness to partner matter too, and every dedicated resource carries an opportunity cost. Gartner also reports that a key account manager handles seven to eight key accounts on average, which caps how many accounts a team can serve this way.

A fire protection company's top 10 customers produce 35% of revenue. It names four of them as key accounts based on growth potential and willingness to plan jointly. Each gets a dedicated account manager and an executive sponsor who meets the customer's facilities leader twice a year.
