Develop a Professional Excel-Based Financial Decision System

I am seeking a freelancer to create a structured and professional Excel-based decision system for financial analysis. The deliverables include: - A well-structured workbook with multiple sheets (data input, validation, calculations, and outputs). - Automated calculations and formulas for data processing. - Data validation controls to ensure data quality (e.g., missing values, duplicates). - A clean and professional dashboard to visualize key metrics and support decision-making. - Scalable design for future expansion. - Clear documentation explaining the system's functionality and maintenance. The system must prioritize data integrity, logical structure, and maintainability to ensure reliability in financial decision-making. The project will follow a phased approach: 1. Structure and core logic development. 2. Validation and automation implementation. 3. Dashboard creation and refinement. Timeline: 2–4 weeks, with flexibility if needed to ensure quality.
