Barter is a system of exchange where goods or services are directly traded without using money. It is a new way to do business in a surplus economy, allowing businesses to get what they need while liquidating merchandise without cash. Using modern exchange networks, virtually any product or service can be traded for another, and credits are used like money for other valuable goods or services. With room for profit incentive, some people are even able to establish their own independent businesses from the trades they initiate on the network.
