A barter system is a method of trade where goods or services are exchanged directly between two parties without the need for the use of money as a medium of exchange. In this system, individuals or entities negotiate and agree upon the value of the items being exchanged. It can involve the exchange of goods for goods (such as trading a cow for a bushel of wheat) or goods for services (such as exchanging carpentry work for a haircut). The barter system was a common means of trade in early human civilizations before the concept of money was introduced.
