A customer is an individual or organization that purchases goods or services from a business. They play a crucial role in the economy by driving demand and influencing market trends. Customers can be classified into different categories, such as retail customers, who buy products for personal use, and business customers, who purchase items for commercial purposes. Understanding customer needs and preferences is essential for businesses to succeed. Companies often conduct market research to gather insights about their customers, which helps them improve their offerings and enhance customer satisfaction. Satisfied customers are more likely to become repeat buyers and recommend the business to others.
