This study examines the influence of FinTech Paylater, Financial Well Being (FW), Behavioral Finance (BF), and Digital Financial Literacy (DFL) on the sustainability of Micro, Small, and Medium Enterprises (MSMEs) in South Sumatera, Indonesia. Using a quantitative explanatory design, data from 563 MSME owners were collected through a structured questionnaire and analyzed using Structural Equation Modeling–Partial Least Squares (SEM–PLS). The results show that FinTech Paylater, FW, BF, and DFL have positive and significant effects on MSME sustainability, with DFL emerging as the strongest predictor. Paylater services support sustainability by improving liquidity and access to short-term financing, while FW enhances financial stability and resilience. BF shapes financial decision-making through behavioral control and risk awareness. The integrated model explains 61% of the variance in MSME sustainability and demonstrates that digital capability and psychological factors jointly determine whether FinTech is used productively or consumptively. The findings provide theoretical contributions to the literature on FinTech and MSME sustainability and offer practical implications for policymakers and FinTech providers in designing targeted Digital Financial Literacy programs and responsible Paylater schemes for MSMEs in emerging economies.
