Over the past decade, business activities have advanced electronically with mobile phones emerging as a significant channel for commercial transactions. How consumers are embracing mobile payments has received major attention in the literature. We shift focus to the microentrepreneurs, including small merchants and informal retailers, who constitute a bulk of developing economy markets. With the recent popularity of mobile payments among microentrepreneurs due to the demands of the Covid-19 pandemic, we now enquire about its long-term continuity. To acknowledge the entrepreneurial mindset driving microentrepreneurs to continue using mobile payments, we draw from the Entrepreneurial Orientation framework (Lumpkin & Dess, 1996) and develop a model that captures entrepreneurial characteristics of the technology like autonomy, innovativeness, competitive externalities, and customer expectations. Using the findings from a survey of 208 microentrepreneurs operating from an urban marketplace in India, we propose how mobile payment can contribute to sustainable development through long-term financial inclusion.
