Case Study: Owens Corning achieves 74% auto-approval and same-day expense processing with AppZen

Owens Corning digitizes expense management

Owens Corning, a global manufacturing company with 19,000+ employees, struggled with “invisible” travel and expense (T&E) spend that was hard to monitor before payment. Their finance team relied on manual post-payment audits and rules-based controls in SAP Concur, but employee-entered data gaps and limited visibility made policy violations, misuse, and recovery of paid funds difficult to manage.

To address this, Owens Corning implemented AppZen’s Expense Audit solution with SAP Concur integration. AppZen’s AI automated receipt analysis and flagged high-risk expenses, helping Owens Corning achieve a 74% auto-approval rate, same-day expense processing in many cases, and a one-day reduction in audit turnaround time, while saving 2,000 manual audit hours annually.
