This study analyzes the impact of Sustainability Supply Chain Management (SSCM), Service Innovation, and Product Innovation on Competitive Advantage and Customer Satisfaction at PT X, with Competitive Advantage as a mediating variable. Data from 71 respondents were analyzed using Partial Least Squares-Structural Equation Modeling (PLS-SEM). The results show that SSCM positively affects Customer Satisfaction (p-value = 0.000) but does not impact Competitive Advantage (p-value = 0.606). Service Innovation has no significant effect on either Competitive Advantage or Customer Satisfaction (p-value = 0.303 and p-value = 0.363). Product Innovation negatively affects Competitive Advantage (p-value = 0.001) but positively impacts Customer Satisfaction (p-value = 0.000). Competitive Advantage mediates the relationship between Product Innovation and Customer Satisfaction (p-value = 0.033), but does not mediate the relationship between SSCM and Customer Satisfaction or Service Innovation and Customer Satisfaction. These findings suggest that PT X should focus on product innovation to enhance competitive advantage, while improving sustainability and service innovation communication to maximize customer satisfaction
