The sample in this study consisted of 40 frontliner employees who directly interact with customers. Data were collected through questionnaire distribution and documentation. The analytical tools used in this study included multiple linear regression analysis, partial correlation coefficient, multiple correlation coefficient, coefficient of determination, and hypothesis testing using t-test and F-test processed with IBM SPSS version 30. The results of the multiple linear regression analysis produced the equation Y = 1.812 + 0.294(X1) + 0.283(X2) + 0.342(X3). This equation indicates that Sales Person Behavior (X1), Customer Relationship Management (CRM) (X2), and Sales Promotion (X3) have a positive effect on Sales Performance (Y).
