Step-by-step explanation:
The employer of a broker is known as the Principal. In the context of a business, the principal is the entity for whom a broker acts as an agent, carrying out buying and selling transactions. Broker roles can differ greatly depending on the industry, but they often serve as intermediaries between the principal and the end customer or client, facilitating transactions or negotiations. For example, in real estate, a broker may help a principal sell a property or in the stock market, a broker may buy or sell securities on behalf of a principal.
