The study focused on the factors contributing to customer satisfaction in e-logistic services. The questionnaire used in this study was developed based on previous studies with proven validity. The structural equation model (SEM) was tested using SPSS and Amos 22 with a sample size of 320 respondents. Research results revealed four factors that affect customer satisfaction: payment method, shipping information, information security, and shipping time. Shipping cost and order fulfillment were found to have insignificant impacts. Information technology was proven to have a mediating role in improving customer satisfaction.
