3. Problem Statement In today's digital age, businesses are increasingly turning to e-commerce as a means of reaching a wider customer base and offering convenient shopping experiences. Small to medium-sized businesses, particularly those in retail, are keen to establish an online presence to remain competitive and cater to changing consumer preferences. The need arises for a robust e-commerce shopping cart system that can seamlessly integrate with existing websites or standalone platforms, allowing businesses to showcase and sell their products online.
