Overview

This project demonstrates an end-to-end business intelligence workflow for a fashion e-commerce company.

The objective was to analyze product performance, customer behavior, and revenue drivers to support strategic decision-making.

A synthetic dataset was created using Python and analyzed in Power BI to deliver a decision-ready dashboard.

The case links customer behaviour and product performance to commercial decision-making.

Dashboard summarizes key commercial KPIs, including revenue, AOV, customer base, and repeat rate.

Business Objective

How can we evaluate product performance across revenue, profitability, and volume to identify:

  • High-performing products worth scaling
  • High-volume but low-margin products requiring pricing review
  • Underperforming products needing strategic action
  • Category-level growth opportunities

Analytical approach

The dataset simulates a mid-sized fashion e-commerce company:

  • 45,000 orders
  • 8,000 unique customers
  • 2.68 M€ total revenue
  • 92.89% repeat rate

Approach:

  • Generated a structured synthetic dataset using Python
  • Stored and queried data using SQL (SQLite)
  • Aggregated performance metrics (revenue, margin, AOV)
  • Modeled data in Power BI using a star schema
  • Built interactive dashboards with KPI-focused visuals

Key questions

  • Is revenue growing sustainably?
  • What drives repeat purchases?
  • Are discounts improving revenue or eroding margin?
  • Which customer segments generate the most value?
  • Is customer retention stable?

Recommendations

Based on the analysis:

  • Increase marketing investment in high-margin women´s products.
  • Review pricing strategy for high-volume, low-margin items.
  • Develop targeted campaigns to grow niche high-margin products.
  • Continue leveraging strong repeat customer behavior for retention-driven growth.
