1. Executive Summary

In response to our client’s declining profit margins across multiple sales channels, a comprehensive data-driven approach was adopted using Power BI to analyze sales, customer behavior, marketing costs, and product returns. This project aimed to pinpoint unprofitable sales channels, identify customer segments contributing to revenue versus refunds, and optimize discount strategies to improve overall profitability.

2. The Problem

Our client’s business faced a significant challenge in maintaining profitability due to the following key factors:

1. Unclear Profitability by Channel – Lack of visibility into which sales channels were contributing to or eroding profit margins.
2. High Return Rates in Certain Customer Segments – Unidentified customer groups responsible for an increasing number of refunds.
3. Excessive Discounting Without ROI Measurement – Marketing expenditures on discounts were not yielding proportionate revenue growth.

3. Solution Approach

In order to address the challenges of declining profit margins, we developed a Power BI-driven analytics solution involving the following key steps:

Step 1 – Data Integration

• Consolidating sales, marketing, and customer data from various channels.
• Cleaning, transforming, and structuring data in a star schema format to enable efficient analysis.
• Establishing relationships between key datasets, including sales transactions, customer profiles, discount records, and refund logs.

Step 2 – Dashboard Development

• Designing an interactive Power BI dashboard to provide insights into:

1. Channel Profitability – Identifying high-performing and underperforming sales channels.
2. Customer Segment Analysis – Tracking refund patterns and segment-wise profitability.
3. Discount Effectiveness – Measuring revenue impact vs. cost of discounting strategies.

• Utilizing mathematical formulas and DAX calculations to derive key profitability metrics.

Step 3 – Implementation

• Deploying the dashboard for Sales, Marketing, and Finance teams to track performance.
• Training teams to interpret data insights and adjust strategies accordingly.
• Providing customized reports and recommendations to optimize pricing, reduce refund rates, and enhance marketing ROI.

The Power BI Dashboard provided clear visibility into sales channel profitability, customer return behavior, and marketing efficiency. By adjusting marketing strategies and discounting policies, the business improved profit margins by 50% and enhanced overall financial performance.
