A more thorough explanation:

A buyer is a person or organization that purchases goods or property from a seller. This can be an individual or a company.

For example, if you go to a store and buy a new shirt, you are the buyer and the store is the seller. Similarly, if a company purchases new equipment from a supplier, the company is the buyer and the supplier is the seller.

Buyers are important because they drive the economy by creating demand for goods and services. Without buyers, businesses would not be able to sell their products and the economy would suffer.
