This study aims to analyze the influence of product innovation, product quality, and service quality on customer satisfaction in the Risqi Tailor Sewing Business. The study uses a quantitative approach with a population of 730 Risqi Tailor customers in 2023. The number of samples was determined using the Slovin formula with an error rate of 10%, so that 87 respondents were obtained. Data were collected through a Likert scale questionnaire and analyzed using SPSS version 25 through validity, reliability, classical assumptions, multiple linear regression, multiple correlation, determination coefficient, t-test, and F-test. Product quality had a positive and significant effect with a t-value of 9.952 and a significance of 0.000. The quality of service also had a positive and significant effect with a t-value of 2.432 and a significance of 0.017. Simultaneously, product innovation, product quality, and service quality had a significant effect on customer satisfaction with an F value of 107.225 and a significance of 0.000. Square's R-value of 0.795 indicates that 79.5% of the variation in customer satisfaction is explained by all three study variables, while the remaining 20.5% is explained by factors other than the model. The most dominant variable is product quality.
