Advance development in information technology and communication have contributed to a great economic efficiency. Companies that can take advantage and operate more efficiently tend to lower product prices and increase delivery time. This is expected to increase customer satisfaction and repurchase intention. The research paper seeks to identify the mediating role of customer satisfaction between e-service quality and repurchase intention in the online business sector in Malaysia. E-service quality was measured by three variables, namely, website design, ease of use, and security. Good service quality tends to satisfy customers and leads to repurchase intention behaviour. The data were collected from online shoppers in Kuala Lumpur, Malaysia. A non-probability sampling technique using Purposive Sampling was used in this study. A total of 210 questionnaires were collected data and analyzed using Statistical Package for the Social Science SPSS software version 29. The findings show that all the selected three-dimensions of e-service quality (website design, ease of use and security) have significant relationship with the repurchase intention of the online shoppers in Kuala Lumpur. The findings also noted that Customer Satisfaction has influenced the significant relationship (a mediated effect) between e-service quality and repurchase intention.
