Sales Analytics Dashboard
Comprehensive Power BI dashboard providing end-to-end sales analytics, customer insights, inventory management, and marketing campaign performance tracking
Project Overview
Developed a comprehensive Power BI sales analytics solution that consolidates data from multiple sources to provide actionable insights across sales performance, customer segmentation, inventory management, and marketing campaign effectiveness. The dashboard serves as a central hub for data-driven decision making across the organization.
Business Challenge
The sales team struggled with fragmented data across multiple systems, making it difficult to get a holistic view of business performance. Key stakeholders needed real-time visibility into sales trends, customer behavior, inventory levels, and marketing ROI to make informed strategic decisions. Manual reporting processes were time-consuming and often provided outdated insights.
