Abstract

The growing utilization of digital financial services has driven the Flip application to evolve into one of the most widely used fintech platforms.

This study aims to analyze the influence of E-Service Quality and E-Satisfaction on E-Loyalty among Flip users in the Cileunyi District. The research subjects consist of Flip application users residing in Cileunyi District. This study employs an associative quantitative method, with data collected through questionnaires and literature review. The sampling technique used is non-probability sampling with a purposive sampling approach, involving 100 respondents. The findings reveal that E-Service Quality has a significant effect on E-Loyalty, indicated by tvalue > ttable (10.654 > 1.984) and a significance value of 0.000 < 0.05, contributing 53.7% to user loyalty. Furthermore, E-Satisfaction also shows a significant effect on E-Loyalty with tvalue > ttable (12.311 > 1.984), a significance value of 0.000 < 0.05, and a contribution of 60.7%.
