Case Study: BESTSELLER trims fraud and loss and saves millions with Microsoft Power BI

Bestseller - Customer Case Study

Bestseller, the global fashion retailer, needed a way to quickly detect and investigate in-store fraud and inventory loss across thousands of stores while protecting employee trust. To address this, Bestseller deployed Microsoft Dynamics 365 Fraud Protection—supported by Microsoft Power BI for analytics—to spot suspicious transaction and inventory patterns and accelerate investigations without casting unfair suspicion on staff.

Using Dynamics 365 Fraud Protection in a 76-store pilot, Bestseller’s AI-driven solution flagged 15 potential fraud cases (five of which the fraud team had already found) and produced measurable improvements: a 1.2% reduction in discount fraud and a 2.9% reduction in return fraud, outcomes that are expected to translate into millions of dollars in savings as the rollout expands. Bestseller is scaling the deployment across Europe and beyond, empowering managers with faster insights and leveraging Microsoft Power BI as its global business-intelligence platform.
