Ranchi, as a growing tier-II city, represents a transitional marketplace in which customers are gradually shifting from physical stores to digital shopping environments. The present study examines customer satisfaction in e-commerce companies operating in Ranchi by analyzing the factors that influence user experience, expectations, trust formation, and post-purchase behavior. Customer satisfaction in online shopping is a multidimensional construct shaped by both functional performance and psychological perception. Unlike conventional retail environments where customers physically evaluate products before purchase, e-commerce transactions require customers to rely on platform credibility, digital interface quality, delivery assurance, and service responsiveness. Consequently, satisfaction depends heavily on reliability, perceived security, and confirmation of expectations after product delivery. The research identifies that Ranchi consumers evaluate e-commerce services through three progressive stages: pre-purchase evaluation, transaction experience, and post-delivery assessment. During the pre￾purchase stage, customers focus on platform reputation, product information clarity, and payment safety. During the transaction stage, website usability, payment convenience, and order confirmation communication influence perceived service quality. During the post-delivery stage, product authenticity, delivery timeliness, return policy efficiency, and complaint resolution determine overall satisfaction. The study further observes that trust acts as the central psychological variable linking service performance with satisfaction outcomes. In developing digital markets, consumers prioritize risk reduction over convenience. Secure payment options, transparent policies, and reliable logistics significantly increase comfort and willingness to purchase online. In contrast, delayed delivery, incorrect products, and complex refund procedures generate dissatisfaction even when pricing advantages exist. Consumer behavior in Ranchi demonstrates demographic variation. Younger consumers emphasize speed, interface design, and product variety, while working professionals prioritize reliability and time efficiency. Household decision-makers and first-time users emphasize safety and return assurance. Cashon-delivery options and real-time tracking systems substantially improve confidence among new users, indicating that satisfaction is closely connected to perceived control over the transaction. The findings suggest that e-commerce satisfaction in emerging cities is not solely driven by technological convenience but by the platform’s ability to reduce uncertainty and create psychological assurance. Therefore, customer satisfaction should be interpreted as a relational outcome developed through consistent performance, transparent communication, and dependable service recovery mechanisms. The study contributes by contextualizing customer satisfaction within semi-urban digital adoption environments. It highlights the necessity for localized service strategies rather than uniform national approaches. E-commerce firms operating in Ranchi must integrate logistics reliability, trust-oriented communication, and simplified service procedures to maintain long-term customer engagement.
