For a business to achieve long-term profits, customer relationship is of utmost importance. To establish a long-term relationship with the customers and to achieve customer return, a business needs to be based on ethics. The trustworthiness of a business, its customer service, customer care, its way of dealing with them, and its urge to retain old customers, is a part of ethics in business. Business ethics leave a long-lasting and positive impression on the customers' minds. This leads to trust-building, which helps a business retain old customers and fetch new ones.
