The retail industry in India has undergone a radical transformation, with the adoption of Omnichannel marketing strategies becoming increasingly critical for business success. In metropolitan cities like Mumbai, where customers are exposed to diverse digital and physical retail options, ensuring a seamless customer experience across all touch points is a significant challenge. This study focuses on the integration of offline and online channels and their direct influence on customer satisfaction, loyalty, and purchasing decisions in Mumbai’s retail sector. The paper also highlights barriers faced by retailers in implementing effective Omnichannel practices. The research employs both primary and secondary data collection methods, drawing insights from structured questionnaires and published reports on the retail sector. Statistical tools such as Chi-square, ANOVA, Correlation, Regression, and Factor Analysis are used to analyze the collected data. A structured model is also proposed to evaluate the relationship between Omnichannel strategies and customer experience outcomes. Findings suggest that Omnichannel strategies significantly influence customer perceptions, with personalization, consistency, and convenience emerging as key factors. The results of the study not only contribute to academic literature but also offer practical implications for retailers aiming to strengthen their customer engagement and competitive position. The paper concludes with recommendations for retailers to enhance their Omnichannel approach by addressing integration issues, improving technology adoption, and aligning customer needs with business strategies.
