Expense management constitutes a fundamental element of organizational financial strategy, demanding precise cost allocation, accurate forecasting, and continuous optimization. Traditional expense tracking relies on rigid categorization systems, labor-intensive reconciliation processes, and retrospective analyses lacking transparency in allocation workflows, significantly hindering integration with modern machine learning frameworks. This article proposes a transformative approach through ML models built upon meticulously structured expense hierarchies alongside discrete hierarchies for booking expenses and revenues. The framework establishes standardized expense taxonomies, organizes financial data into Direct, Allocated, and Variable expense categories atop cost center and profit center hierarchies, and implements ML models to enhance expense forecasting accuracy and allocation efficiency. The resulting system automates cost attribution, detects anomalies in allocation patterns, and optimizes expense management, ultimately strengthening organizational financial decision-making processes and supporting long-term cost-optimization strategies.
