A significant challenge in e-commerce is the inability of consumers to physically inspect products, forcing them to rely on perceived quality derived from other consumers’ experiences. However, gaps remain in understanding which dimensions of perceived quality are most frequently mentioned and influential for customer satisfaction, particularly in emerging markets like Indonesia. This study investigates these gaps by identifying key perceived quality aspects and examining their impact on satisfaction, with a specific focus on the moderating role of logistics delivery services. Using a large language model (LLM), specifically Google’s Gemma 2, we performed aspect-based sentiment analysis on 5000 smartphone reviews from Indonesian e-commerce. Logistic regression models incorporating interaction variables were employed to evaluate the relationships. The results identify the most frequently mentioned aspects of perceived quality: Logistics delivery services, Functionality, Originality, Responsiveness, and Packaging. While Logistics delivery services was the most mentioned aspect, Packaging had the most significant direct influence on satisfaction. Notably, Logistics delivery services also play a significant moderating role, enhancing the positive effect of other perceived quality aspects on satisfaction. These findings suggest that Logistics delivery services contribute directly to satisfaction and amplify other aspects, resulting in greater customer satisfaction. The study contributes to the literature by demonstrating LLM-driven aspect-based sentiment analysis methods and expanding the concept of perceived quality to include service aspects, thus promoting a more complete consideration of perceived quality in e-commerce.
