Online stores that evoke the physical analogy of buying products or services at a regular “brick-and-mortar” retailer or shopping center follow a process called business-to-consumer (B2C) online shopping. When an online store is set up to enable businesses to buy from another business, the process is instead called business-to-business (B2B) online shopping. A typical online store enables the customer to browse the firm’s range of products and services, view photos or images of the products, along with information about the product specifications, features and prices. Unlike physical stores which may close at night, online shopping portals are always available to customers.
