A more thorough explanation:

A business transaction is an action that impacts a person or company's financial or economic interests. This can include making a contract, buying or selling goods or services, or exchanging money.

For example, when a customer purchases a product from a store, it is considered a business transaction. The customer is exchanging money for the product, and the store is receiving payment for the goods sold.

Another example of a business transaction is when a company hires an employee. The employee is providing their services in exchange for a salary, which impacts both the employee's and the company's financial interests.

Overall, a business transaction is any action that involves the exchange of money, goods, or services and has an impact on the financial interests of the parties involved.
