The incorporation of computers into contemporary company operations has significantly altered productivity and communication, essentially making paper-based file systems outdated. The advancement of technology has made it possible to manage data more accurately, streamline procedures, and obtain information more quickly. Better managerial skills are now a trademark of the digital age, allowing companies to accurately and quickly respond to information requests. Innovative business models have also been made possible by the transition to digital technology, especially in the areas of customer engagement and operational management. A more dynamic and responsive business environment has been made possible by the automation of repetitive processes, real-time data analysis, and enhanced communication channels. This has allowed organisations to respond to shifting market conditions with accuracy and agility. A significant advancement in this digital shift is the emergence of e-commerce platforms. These platforms have facilitated a smooth and mutually beneficial relationship between businesses and customers. Online shopping provides customers with an unparalleled level of ease, enabling them to peruse, evaluate, and buy things from the comfort of their own homes. These websites give businesses access to a wider market, an extra source of income, and insightful data analytics on consumer behaviour. By providing easy navigation, safe payment choices, and personalised experiences, the e-commerce model improves client engagement. The transition to e-commerce has increased revenues as well as customer happiness and brand loyalty by offering a convenient and effective purchasing experience. For Computer Technologies Union (CTU) in Owerri, the project's goal was to create an e-commerce website that would improve customer interaction and business operations in response to current trends. To enable simple online purchases, the website was built with a feature-rich catalogue of store merchandise and an intuitive shopping cart. The system was designed to be reliable, scalable, and effective by utilising a three-tier design. Although the middle layer, which used PHP, handled business logic with ease, the backend MySQL database ensured dependable data management. Shopping was simple and easy with the client interface, which could be accessed via a web browser. The speed and precision of service delivery at CTU Owerri were greatly enhanced by the new system after it was fully implemented. While the firm benefited from increased operational efficiency and the ability to better meet customer expectations, customers had a convenient and pleasurable shopping experience. In addition to modernising CTU Owerri's operations, this calculated decision gave it a competitive edge in the online market.
