The research method was quantitative based on the structural equation modeling SEM with the sample size of 551 individual customers in small and medium enterprises in Vietnam.

This relationship was proved with two intermediary factors, namely enterprises’ brand value and customer loyalty. These conclusions not only revealed the research’s contributions but also laid the foundation for further studies. Based on the research findings, the author proposed recommendations to avoid customers’ switching and minimize business loss due to customers’ switching behavior in using products and services.
