In the present study, an integrated model was developed to identify key determinants and examine their impact on customers’ satisfaction to adopt or reject a specific digital payment system for payment purposes. A conceptual framework was proposed and empirically validated using data collected through a questionnaire survey. Out of 350 distributed questionnaires, 292 valid responses were retained for analysis. Structural equation modelling (SEM) was employed to assess the robustness of the proposed model and to test the hypothesised relationships. The findings indicate that perceived value, trust, compatibility, and social influence significantly influence consumers' satisfaction to use digital payment system. However, perceived enjoyment was found to have a comparatively weaker effect on adoption intention. Among all determinants, trust emerged as the strongest predictor of satisfaction, followed by compatibility, highlighting their critical role in the context of mobile payments. The study was limited to two digital payment systems and focused on a specific age group within a single city, which may restrict the generalizability of the results. Nevertheless, understanding the multifaceted nature of purchase intention can help digital payment service providers build consumer trust and encourage more frequent use of mobile payment services. The findings suggest that service providers should strategically manage all influential factors as proactive measures to enhance digital payment system adoption. The proposed study can serve as a valuable work for organisations seeking to effectively manage and strengthen users’ adoption of payment apps
