A customer is an individual or organization that purchases goods or services from a business. Customers play a crucial role in the economy, as their spending drives demand and influences production. They 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 tailor their offerings. Satisfied customers are more likely to become repeat buyers and recommend the business to others, enhancing its reputation and profitability.
