The term "business transaction" refers to any exchange or agreement between two parties involving the transfer, purchase or sale of goods and/or services. This can include a wide range of activities such as purchasing supplies for a company, making payments to vendors, issuing invoices for products or services rendered, entering into contracts with clients or customers, and many others. The goal of these transactions is typically to facilitate the exchange of value between two parties, either by providing goods or services in return for payment, or by acquiring needed resources in order to conduct business operations effectively.
