Design of E-Commerce And Business System for Yastore Grocery Shop Based on a Website

Abstract

The development of technology in the globalization era has brought significant changes to the business world, where competition among entrepreneurs is becoming increasingly intense. This condition requires every business to innovate, particularly in marketing and service systems, to remain competitive and sustainable. yastore is a grocery store that provides various basic daily necessities; however, its promotional and sales activities are still carried out manually, such as direct purchases at the store and word-of-mouth marketing. This approach is considered less effective because modern consumers tend to prefer fast and practical transaction processes through digital media. This study aims to design a website-based e-commerce system as a promotional and online transaction platform for yastore. The development method used is the Waterfall model, which includes stages of requirements analysis, system design, coding, testing, and maintenance. The results show that implementing an e-commerce website can expand market reach, simplify transactions between sellers and customers, and serve as an effective and efficient promotional medium to enhance business competitiveness sustainably.
