Global business management has experienced dramatic transformation with the expedited evolution of electronic payment facilities and growth in cross-border business. Global trade previously relied heavily on conventional banking networks, which were not just time-consuming but also costly and less accessible. Fintech facilities, blockchain technology, and mobile payment applications have transformed digital payments into an integral force behind global commerce. This paper examines the role of electronic payment systems in the development of cross-border trade and how the technologies have put across a new paradigm in international business administration with special reference to India and US. It aims to highlight opportunities, challenges, and strategic implications of implementing digital payment in overseas markets. Systematic review of literature and secondary data analysis were employed to evaluate global trade flows, fintech adoption patterns, and regulatory problems. Comparative analysis between developed and emerging economies has been presented to understand the different impacts of digital payment solutions. Results show that electronic payments enhance efficiency in international trade since they reduce transaction costs, improve speed, and increase transparency. They also result in higher financial inclusion as SMEs are enabled to participate in global trade. However, regulatory variance, cybersecurity threats, and interoperability issues remain significant impediments. Digital payments are an innovation catalyst for cross-border business management, transforming supply chain efficiency, consumer trust, and cross-border competitiveness. Policy makers and enterprises must collaborate to combat challenges, synchronize rules, and embrace innovation to unlock the full potential of digital payments in cross-border trade.
