Retailing is the final step in the distribution process that connects producers to final consumers. It covers diverse products from apparel and consumer goods to financial services and leisure. In developed countries, three-fourths of retail trade is conducted by organized sector chains that have replaced individual small stores. Retailing involves purchasing goods in large quantities from manufacturers or importers and selling smaller quantities directly to end-users, coordinating all aspects of bringing a product to market from design to post-purchase customer service. The industry contributes significantly to economic growth globally and is one of the fastest changing industries today.
