Affiliate marketing strategies are also included in the definition of an e-commerce business. You can use e-commerce platforms such as social media, your website, or a well-known retailer such as Amazon to increase online sales. LearnBox, an app platform for students and academic institutions, is introduced in the research. It started as a website and then developed into a mobile app. LearnBox promotes sustainability by improving user experience and integrating a barter system for educational content. LearnBox expands its services to neighborhood stores in the National Capital Region, intending to contribute to the changing e-commerce landscape by addressing particular challenges and providing a long-term solution for exchanging educational materials. The study’s modified waterfall effect diagram has the benefit of enabling researchers to concentrate on every platform development sequence and go back and verify earlier iterations as needed. This adaptability allows for comprehensive validation as the project progresses through later development phases. The post-study system usability questionnaire (PSUQQ) is used in the study to gauge how user-friendly the researcher’s website is. To sum up, the data collected by the researchers indicates that the participants had positive experiences. Overall, the LearnBox e-commerce platform proved to be successful.
