A key account coordinator is in charge of maintaining relationships with a company’s customers. The responsibilities of a key account coordinator are to act as support for a company’s most important clients, acting as a liaison between the customer and the business. Because the role of key account coordinator is applicable to so many industries, and because key clients can range in size, you must be flexible in approach to your duties and be willing to provide whatever support and customer service is necessary to ensure the continuance of a productive business relationship. If the relationship is in sales, then you ensure orders are received and delivered on time. If your business manages financials, you oversee the client’s brief and provide reports on the status of their accounts. You do whatever is needed to best serve the needs of your clients.
