The central focus of commercial activities is trading. Commercial activities refer to the exchange of goods or services between businesses or individuals with the primary objective of generating profit. Trading involves the buying and selling of goods or services in exchange for money or other forms of payment. It is the foundation of commercial activities as it allows businesses to acquire goods or services they need and sell products they have manufactured or acquired to generate revenue. While pricing, advertising, and marketing are important aspects of commercial activities, they are primarily aimed at facilitating trading and generating revenue for the business.
