E-business has transformed the way companies operate globally. It allows transactions to occur through digital platforms, expanding business across borders. In Bangladesh, this shift has been particularly evident in the growing e-commerce sectors, like retail, transport, groceries, electronics and medicine. The rise of online retail has enabled Bangladeshi businesses to compete in global markets, offering a variety of products at competitive prices. Social media has further enhanced customer engagement in Bangladeshi e-commerce sectors. Many companies now target specific demographics by leveraging online platforms for sales, marketing and customer services. Despite the advantages, e-businesses in Bangladesh face challenges, including cyber-security risks. The government should take steps to help in this regard ensuring trustworthiness and security so that this booming industry can succeed.
