One factor that supports effective CRM is Knowledge Sharing, defined as the practice of employees sharing information and knowledge with customers during service interactions. This study aims to examine the effect of Knowledge Sharing on Customer Relationship Management at Coffee Shop Tanaka. A quantitative approach was employed involving 100 customers selected using purposive sampling. Data were collected through a five-point Likert-scale questionnaire and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 4. The results indicate that Knowledge Sharing has a positive and significant effect on Customer Relationship Management, with a path coefficient of 0.758, a T-statistic of 14.217, and a p-value of 0.000. Furthermore, the R² value of 0.575 indicates that Knowledge Sharing explains 57.5% of the variance in Customer Relationship Management. These findings demonstrate that employees' knowledge-sharing practices enhance customer interaction, strengthen trust, and foster long-term customer relationships. This study provides empirical evidence that Knowledge Sharing serves as an important strategy in supporting the implementation of Customer Relationship Management within the coffee shop industry.
