Small and medium-sized enterprises (SMEs) are vital contributors to global economies, but they often face unique financial challenges that threaten their long-term stability. This review presents a comprehensive analysis of forecasting financial stability in SMEs, focusing on strategic budgeting and revenue management as key pillars. Strategic budgeting plays a crucial role in aligning financial plans with business goals, managing risks, and adapting to market changes. Techniques such as zero-based budgeting, activity-based budgeting, and rolling budgets offer SMEs flexibility in allocating resources and ensuring optimal cash flow management. Meanwhile, effective revenue management involves the use of pricing strategies, sales channel diversification, and customer segmentation to optimize revenue streams and improve profitability. The interplay between strategic budgeting and revenue management is critical for creating dynamic forecasting models that help SMEs anticipate financial challenges and make informed decisions. By integrating both strategies, SMEs can better manage risks, enhance financial predictability, and achieve long-term sustainability. This review also explores the role of technological tools, such as financial software and predictive analytics, in supporting financial decision-making processes. Tools like customer relationship management (CRM) systems and AI-driven forecasting platforms enable SMEs to optimize revenue potential and refine budgetary practices. The review provides recommendations for SMEs to implement best practices in financial planning, suggesting regular budget reviews and proactive revenue management strategies to respond to market fluctuations. By leveraging strategic budgeting and revenue management, SMEs can enhance their financial resilience and improve their capacity to navigate economic uncertainties. The review concludes with insights into emerging trends in financial forecasting, emphasizing the importance of continuous adaptation to maintain financial stability.
