Case Study: Carnival achieves proactive fraud detection and automated vendor risk scoring with Alteryx

Carnival - Customer Case Study

Carnival’s Internal Audit team needed a repeatable way to detect vendor fraud across its operating companies. Auditors used to manual, Excel‑based sampling and a one‑time investigative work plan, but after a fraud probe they needed a platform to analyze whole populations of vendors and surface high‑risk relationships rather than relying on random samples.

The team built two Alteryx workflows—one to automate manual vendor testing and a second using k‑means clustering to identify outliers—and analyzed 10,000 non‑PO vendors, 275,000 invoices and more than $2 billion in spend. The automated process risk‑ranked vendors, runs in under a minute, enabled focused follow‑ups, and reduced the materiality threshold from $500K–$1M to $250K (and in some cases $100K), accelerating investigations and improving audit coverage and transparency for leadership.
