This study investigated the effect of logistics and policy service quality on customer trust, satisfaction, and loyalty within the quick commerce landscape in Jordan, with a particular focus on generational differences between generation Y (Gen Y) and generation Z (Gen Z) users. A survey of 719 active Q-commerce users revealed that logistics service quality (personal contact quality, shipment condition, product availability, timely product delivery, and order accuracy) significantly affected customer satisfaction, with order accuracy being the most impactful factor. Additionally, both cash on delivery and order discrepancy handling significantly affected customer trust. Finally, customer satisfaction and trust affected customer loyalty, though in multigroup analysis, their relative importance varies between generations. Gen Z prioritizes speed of delivery and less concern on personal contact with delivery personnel. On the other hand, Gen Y values product availability and cash on delivery more than the younger generation. These findings offer valuable insights for Q-commerce platforms to tailor their strategies to the distinct priorities of each generation and enhance customer trust, satisfaction, and loyalty.
