An online marketplace (or online e-commerce marketplace) is a type of e-commerce website where product or service information is provided by multiple third parties. Online marketplaces are the primary type of multichannel ecommerce and can be a way to streamline the production process.
In an online marketplace, consumer transactions are processed by the marketplace operator and then delivered and fulfilled by the participating retailers or wholesalers. These type of websites allow users to register and sell single items to many items for a "post-selling" fee.
Because marketplaces aggregate products from a wide array of providers, the selection is wider, and availability is higher than in vendor-specific online retail stores. Some online marketplaces have a wide variety of general interest products that cater to almost all the needs of the consumers, others are consumer specific and cater to a particular segment. Online marketplaces became abundant in 2014.
Business-to-business (B2B) online marketplaces are platforms that allow companies to buy and sell products or services to other businesses. These marketplaces typically focus on a specific product or service category and are used by businesses to find suppliers, negotiate prices, and manage logistics.
Some examples of B2B online marketplaces include VerticalNet, Commerce One, and Covisint, which were some of the earliest B2B marketplaces to emerge in the early days of e-commerce. More contemporary B2B marketplaces include EC21, Elance, and eBay Business, which focus on specific product or service categories and facilitate complex transactions such as requests for quotations (RFQs), requests for information (RFIs), and requests for proposals (RFPs).
Online marketplaces are information technology companies that act as intermediaries by connecting buyers and sellers. Examples of prevalent online marketplaces for retailing consumer goods and services are Amazon, Taobao and eBay. On the website of the online marketplace sellers can publish their product offering with a price and information about the product's features and qualities.
