Author description:

This model brings together 48,000 events across 4,000 customers and 101 products, revealing $9.38M in net revenue, 14,399 orders, 86,259 units sold, and an Average Order Value of $651.34. One insight that stood out immediately: 3,503 loyal customers drive ~97.7% of total revenue, showing how critical retention is in this business. I designed the dashboard to uncover real commercial levers, identifying high-performing products and vendors, understanding how channels influence purchasing behaviour, and spotlighting where refund rates and attach-rate opportunities lie. I also explored customer loyalty patterns, regional sales differences, and category revenue drivers, building DAX measures and a clean data model to support deep analysis. This project sharpened my skills in modelling, Power Query transformations, UX layout, and creating insights that non-technical users can act on.
