Over the recent years, there has been tremendous ease in monetary transactions; all thanks to a convenient payment platform. The Integrated e-payment system (IEPS) facilitates financial transactions electronically. This study aims to examine the factorial models necessitating the continuous use of the integrated e-payment system in the light of the Unified Theory of Acceptance and Use of Technology (UTAUT) with two additional variables; processing time and processing charges proposed. The study data were collected from 285 valid respondents in Ghana through the random sampling approach. The hypothesis verification was conducted via the SmartPLS. The result of the structural equation modelling indicate that processing charges, processing time, and social influence are the critical influencers of IEPS continuous usage intention. In addition, it also implies that financial institutions and banks liaise with designers to, perhaps, consider consumers’ perspectives in their design; such that will bring about convenience, fast processing and minimal cost in order to foster continuous use.
