Case Study: Mango achieves 97% acceptance and reduced fraud while expanding eCommerce with ACI Worldwide

Mango and ACI Worldwide Increase Acceptance, Reduce Risk and Expand eCommerce Reach

Mango, the global fashion retailer, faced a broad mixture of eCommerce fraud issues while trying to rapidly expand its online business and enter high‑risk geographies. To address this, Mango partnered with ACI Worldwide, adopting ACI’s global fraud solution and leveraging the vendor’s dedicated risk analyst team and fraud management capabilities.

ACI Worldwide implemented a multi‑layered approach—daily rules tuning by analysts, a stream analytics engine (including "time on file"), dynamic 3D Secure, and a self‑service BI portal plus integrated partner tools like device ID—to tailor fraud strategy by market. The result: acceptance rates rose to 97% overall (U.S. acceptance up 7% to 95%), confirmed fraud held at 0.32%, Mango safely expanded across regions, and the retailer scaled to roughly 6 million active eCommerce customers with substantial online sales growth.
