Grab is a ride-hailing platform that offers booking service for taxis, private cars, and motorbikes in South East Asia, including Indonesia. In Indonesia, Grab was ranked second largest, after Go-Jek. Both of them experience very tight company competition, both in offering affordable prices and offering the latest services and features. This study aims to examine and analyze the influence of service quality (reliability, responsiveness, assurance, empathy, tangibles) and price on customer satisfaction of online transportation Grab. The research was designed by using a conclusive experiment, in causal research type, using quantitative and survey methods. The data was taken by providing a questionnaire to 406 respondents using a non-probability sampling method which is an accidental sampling and judgmental sampling method. Analysis method used in the research is Multiple Regression Linear. The result shows that the variable such as reliability, responsiveness, empathy, tangibles significantly gave impact to customer satisfaction. In other hands, assurance did not significantly give impact. The future research in the same topic can use probability sampling method, especially stratified random sampling so that all the consumer population characteristics of Grab which are heterogeneous from various cities will be covered.
