Key account management

What it means

Key account management is dedicated care for the most important customers, those who generate a large share of revenue or have strategic value. Each key customer has an assigned manager, a joint account plan and regular meetings at management level.

The approach rests on the observation that a small number of customers often brings in most of the turnover, in line with the Pareto principle. Losing one of them can hit results hard, so these customers deserve more attention than ordinary sales.

The aim is not just to sell more but to keep and develop the relationship. A key account manager understands the customer's business, goals and problems, coordinates the people in their own company who serve that customer and looks for ways to help it grow. The customer then sees the supplier as a partner.

How it works in practice

First, decide who the key customers are. The criterion is not just turnover but also margin, growth potential, strategic value as a reference and the effort needed to serve them. A customer with high turnover but zero margin may not be key if it consumes more capacity than it brings.

For each key customer an account plan is prepared: annual goals, a map of decision-makers, risks and opportunities for upselling and cross-selling. All communication and agreements are recorded in the CRM so that the relationship does not depend on a single person.

Regular review meetings, often quarterly, compare agreed indicators of quality, delivery and satisfaction. Working with the customer success team and with marketing through account-based marketing helps strengthen the relationship at several levels of the customer's organisation.

What to watch out for

Heavy dependence on a few customers is a financial risk. If one customer accounts for a third of revenue, it can dictate prices and payment terms, and its departure threatens cash flow. Key account management should go hand in hand with spreading revenue across more customers.

A relationship built on one person is fragile. If the key account manager leaves, they may take the customer with them, so it pays to involve more people on both sides, keep records in the CRM and watch for early signs of customer churn, such as falling order volumes.
