Financial analytics in emerging economies is evolving rapidly with the increasing deployment of Management Information Systems (MIS). These platforms allow businesses, governments, and financial institutions to integrate diverse financial data, generate real-time insights, and apply predictive models to support strategic decision-making. Emerging economies face unique challenges such as limited infrastructure, fragmented data flows, and insufficient digital literacy that often restrict the efficiency and transparency of financial ecosystems. MIS platforms provide a structured approach to overcoming these barriers by enabling automated reporting, reducing human error, and supporting more reliable financial forecasting. This paper investigates the role of MIS-driven financial analytics in advancing transparency, accountability, and sustainability in developing financial systems. Through a review of existing literature, we examine how MIS supports credit scoring, fraud detection, SME financing, and policy formulation. We also propose a methodology that integrates data collection, predictive modeling, and dashboard visualization to improve financial governance and investor confidence. While challenges related to cost, interoperability, and regulatory alignment persist, the broader implication is clear: MIS platforms can serve as foundational tools for inclusive and sustainable financial growth, positioning emerging economies to align with global financial standards.
