Final answer:
One problem that might commonly occur when bartering is the difficultly in entering into future contracts for purchasing goods and services. Additionally, bartering may not work well for perishable goods or in larger economies. Money solves these problems by acting as a medium of exchange and allowing for future transactions.
Step-by-step explanation:
Another problem with the barter system is that it does not allow us to easily enter into future contracts for purchasing many goods and services. For example, if the goods are perishable it may be difficult to exchange them for other goods in the future. Imagine a farmer wanting to buy a tractor in six months using a fresh crop of strawberries. Additionally, while the barter system might work adequately in small economies, it will keep these economies from growing. The time that individuals would otherwise spend producing goods and services and enjoying leisure time they spend bartering.
Money solves the problems that the barter system creates. First, money serves as a medium of exchange, which means that money acts as an intermediary between the buyer and the seller. Instead of exchanging accounting services for shoes, the accountant now exchanges accounting services for money. The accountant then uses this money to buy shoes. To serve as a medium of exchange, people must widely accept money as a method of payment in the markets for goods, labor, and financial capital.

At first, most goods and services were traded as gifts or through bartering between small social groups. Exchanging one form of goods or services for another was known as bartering. This system only works when one person happens to have something the other person needs at the same time. To solve this problem, people developed the idea of a means of exchange that could be used at any time: that is, money.
