This study aims to analyze the factors that influence the acceptance of the SIAPIK application by young entrepreneurs at INSTIKI. Using the Technology Acceptance Model (TAM) and Expectation-Confirmation Theory (ECT), the research identifies the main variables affecting the adoption of this accounting application. The study was conducted through several stages: planning and problem identification, conceptual model and instrument development, data collection, data analysis, and conclusion writing. Data were collected through surveys of INSTIKI’s young entrepreneurs who use or potentially use SIAPIK and analyzed using descriptive statistics and Structural Equation Modeling-Partial Least Squares (SEM-PLS) with SmartPLS 3. The findings provide insights into perceived strategic benefits, performance expectations, and social influence in determining adoption decisions. Furthermore, this study offers practical implications for application developers and recommendations for stakeholders to improve the acceptance and utilization of digital accounting applications.
