Inspiration

Many e-commerce businesses collect large volumes of sales data but struggle to convert it into meaningful insights. The inspiration behind this project was to bridge the gap between raw transactional data and actionable business intelligence by building an interactive dashboard that clearly explains what is happening, why it is happening, and what actions to take next.

What it does

The E-Commerce Sales Performance Analytics Dashboard provides a centralized view of business performance by:

Tracking key sales KPIs such as Total Revenue, Profit, Profit Margin, and Orders

Analysing monthly and seasonal sales trends

Identifying top-performing and underperforming products and categories

Visualizing customer demographics and purchasing patterns

Enabling date and quantity-based filtering

Forecasting future sales trends to support strategic planning

How we built it

The dashboard was built using an end-to-end analytics workflow:

Handled missing values, duplicates, and data inconsistencies

Prepared data using Power Query

Data Modelling & DAX
