The purpose of this study is to identify and experimentally test the key factors influencing customer's e-satisfaction and the intention to reuse MFOAs. The structural linear model was used to test hypotheses by analyzing data of 352 customers who used MFOAs in Ho Chi Minh city. The result indicated that, continuance intention to use MFOAs was driven by two factors of e-satisfaction and habit; while e-satisfaction is influenced by performance expectancy, hedonic motivation, effort expectancy and online review. This research has theoretical contribution as well as practical implications related to online ordering applications nowadays.
