Project brief
I built this interactive dashboard to pinpoint revenue drivers across 300 customers and 50 product lines. Featuring granular weekly distribution and quarterly YoY comparisons, it provides the executive clarity needed to scale the £48.5k average revenue per customer through data-backed inventory and marketing shifts.
Objectives / Questions to answer
Client Request: Assistance in Building a Sales Dashboard in Excel. I would like the dashboard to include the following key features:
• KPIs at the top: Total Units Sold, Overall Sales Revenue, Average Revenue per Customer, and Average Revenue per Product.
• Comparison visuals: Year-over-year (YoY) revenue for 2023 vs 2024, monthly revenue trends, and revenue by weekdays vs weekends.
• Category insights: Revenue generated by category and top products driving sales.
• Customer insights: Top-5 revenue-generating customers, revenue contribution by gender, and revenue breakdown by age segments.
• Regional insights: Regional sales performance and revenue distribution across segments.
• Interactivity: Ability to filter by product categories (Clothing, Electronics, Groceries, Home Appliances, Sports) and by region (East, North, South, West).
