Retail is a key part of the tertiary sector because it serves as the direct link between producers and consumers. Retailers buy goods in bulk from manufacturers or wholesalers and sell them in smaller quantities to individuals in shops, markets, or online platforms. This ensures that people have easy access to a wide variety of products. Retail activities also create employment opportunities and contribute to the economy by generating revenue through sales. Additionally, retail supports other sectors by distributing goods efficiently, making it an essential component of the service industry.
