Money's most essential function is as a medium of exchange to facilitate transactions. Without money, all transactions would have to be completed by barter, which involves direct exchange of one good or benefit for another.
Money is used as a medium of trade because both the buyer and the seller understand the value. This is beneficial because neither party is confused about its worth. For example, if one were to offer a cow as payment for a meal at McDonald's, there may be some mess about the value of the cow.
