This Power BI report explores the performance of an e-commerce business across 12 European countries. It uses more than 9,100 order-line records from 2024 and 2025 to show how sales, customers, inventory, delivery, and returns affect profitability.

The report has five pages:

Finance
See how gross sales turn into net sales and contribution margin. Compare revenue and costs by date, product, market, sales channel, and promotion to find where margins are being reduced.

Customers
Explore customer segments, loyalty tiers, acquisition channels, and markets. Cohort analysis shows how many customers continue buying in the months after their first purchase.

Inventory
Check stock status by product, fulfillment center, and weight class. See where unavailable stock may be causing lost sales and which products need attention based on reorder lead times.

Fulfillment
Track on-time delivery, delivery speed, and whether orders arrive by the promised date. Compare carriers, markets, product weights, and sales channels to find delivery issues.

Returns
See why products are returned and how much those returns cost. The analysis includes refunds, shipping, processing, and lost product value, with breakdowns by return reason, carrier, product, and customer segment.
