What is the term for an exchange between goods or services that does not involve money?

The term for an exchange between goods or services that does not involve money is barter. Bartering is a system where parties directly exchange goods or services without the use of currency as an intermediary. This practice has been used since ancient times and is still relevant in various contexts today, especially in situations where cash is scarce or in informal economies.

In a barter system, each party must have something the other wants, which can sometimes make transactions more complex than monetary exchanges. The absence of money means that the parties must negotiate the value of the goods or services being exchanged, ensuring that each person perceives they are receiving a fair deal.

Other terms such as trade generally imply the involvement of money or market exchanges, cash exchange specifically refers to transactions involving money, and investing pertains to the allocation of resources, typically in the expectation of generating profit over time. None of these fit the description of a direct exchange without monetary involvement, making barter the most appropriate choice.
