E-commerce refers to online trade between merchants located in different countries and jurisdictions. There are three main types: business to consumer, business to business, and consumer to consumer. E-commerce provides benefits like international expansion to sell products globally, increased revenue through higher demand, and improved brand awareness. It also allows merchants to sell low-demand domestic products internationally. To engage in e-commerce, businesses need websites, shopping carts, SSL certificates, payment gateways, merchant accounts, and bank accounts. Developing cross-border e-commerce in Bangladesh could increase exports three times by providing quality, original products to the growing global demand.
