Excellent customer service is about consistently exceeding customer expectations before, during, and after a sale. It is important because most dissatisfied customers do not complain but simply find another provider in the future. It also costs much more to acquire a new customer than retain an existing one. To provide excellent service, understand the customer perspective, be caring, know their needs, and welcome and resolve complaints quickly. Positive attributes include being friendly, accurate, accountable, simple, and respectful. Constantly evaluate performance through customer surveys and research to ensure high quality service.
