It is estimated that over 450,000 businesses in the United States were involved in barter exchange activities in 2010. There are approximately 400 commercial and corporate barter companies serving all parts of the world. There are many opportunities for entrepreneurs to start a barter exchange. Several major cities in the U.S. and Canada do not currently have a local barter exchange. There are two industry groups in the United States, the National Association of Trade Exchanges (NATE) and the International Reciprocal Trade Association (IRTA). Both offer training and promote high ethical standards among their members. Moreover, each has created its own currency through which its member barter companies can trade. NATE's currency is the known as the BANC and IRTA's currency is called Universal Currency (UC).[citation needed] In Canada, the largest barter exchange is Tradebank, founded in 1987. In the United States, the largest barter exchange and corporate trade group is International Monetary Systems, founded in 1985, now with representation in various countries. In Australia and New Zealand the largest barter exchange is Bartercard, founded in 1991, with offices in the United Kingdom,United States, Cyprus,UAE and Thailand.[citation needed]
If you experience odd or unexplained amounts of merchant gold, even after the merchant has restocked, then you probably have another mod loaded after Trade & Barter which has altered the VenderGold leveled lists. To resolve the issue either: 1) Change the load order, and make sure that Trade & Barter loads after the other mod, or 2) Click the "Disable Merchant Gold Options" option from the menu. This will reset the Merchant Gold options and allow the changes from the other mod to prevail without further interference from Trade & Barter.
There might come a time in your business's life when you want to barter your services. In fact, you may find it prudent from time to time to trade your services for the services that another business offers. It helps to have a plan in place for this and to have some safeguards against overextending your services beyond what you can support. After all, if you barter all of your services all of the time, then you'll never earn an income. 

Other anthropologists have questioned whether barter is typically between "total" strangers, a form of barter known as "silent trade". Silent trade, also called silent barter, dumb barter ("dumb" here used in its old meaning of "mute"), or depot trade, is a method by which traders who cannot speak each other's language can trade without talking. However, Benjamin Orlove has shown that while barter occurs through "silent trade" (between strangers), it also occurs in commercial markets as well. "Because barter is a difficult way of conducting trade, it will occur only where there are strong institutional constraints on the use of money or where the barter symbolically denotes a special social relationship and is used in well-defined conditions. To sum up, multipurpose money in markets is like lubrication for machines - necessary for the most efficient function, but not necessary for the existence of the market itself."[13]
