Barter, a method of trade, involves the direct exchange of goods and services without the use of money or a third party. It is a crucial aspect of trade in countries with non-convertible currencies. This form of trade can be traced back to ancient times and is still prevalent in some societies today. Barter relies on mutual agreement between two parties and requires a thorough understanding of the value of goods and services being exchanged. It is an efficient alternative to traditional monetary transactions and can foster strong relationships between individuals and businesses.
