An e-marketplace is a virtual online market where organisations register as buyers or sellers to conduct business-to-business e-commerce over the internet.
There are many types of e-marketplace based on a range of business models. They can be operated by an independent third party, or be run by some form of industry consortium that has been set up to serve a particular sector or marketplace.
Services offered by e-marketplaces include electronic catalogues for online purchasing of goods and services, business directory listings and online auctions.
