Customer perception and happiness are critical to attaining sustainable growth and profitability in the fiercely competitive banking industry. Banks increasingly focus on building long-term customer relationships to enhance loyalty, reduce price sensitivity, and strengthen their market position. In this context, instead of completely replacing traditional branch-based services, electronic banking services have become an essential part of contemporary banking. The current study intends to investigate consumers' opinions of the e-banking services provided by banks and gauge their degree of satisfaction with technology-enabled banking self-services. The study is based on primary data that was gathered through a structured survey procedure from 100 respondents. Customer satisfaction across a range of e-banking service parameters was assessed using ranking algorithms. The findings highlight that customer expectations regarding e-banking services are significantly high due to rapid technological advancements and intense competition among banks with relatively similar service offerings. Customer satisfaction is therefore identified as a key determinant of continued usage, positive word-of-mouth, and customer retention. The study underscores the importance for banks to prioritize customer-centric digital strategies to enhance satisfaction and strengthen competitive advantage in the evolving Indian banking landscape.
