Travel & Expense Audit Resources

Travel and expense claims are individually small but collectively significant, and they are highly visible. A weak T&E process can lead to leakage, policy breaches and reputational damage — especially when senior employees are involved.

A travel and expense audit typically reviews the policy itself, the approval process, the quality of receipts and supporting evidence, corporate card programs, and how management monitors spending patterns. Analytics across the full claims population are particularly effective in this area.

Common risks include approvals given without real review, claims without valid receipts, split claims to stay below limits, duplicate submissions, personal spending on corporate cards, hotel or taxi usage that breaches policy, and exceptions that are approved routinely.

The resources below give you everything needed for a focused T&E audit: a step-by-step guide that goes beyond receipt checking, a checklist covering policy, approvals and red flags, and a travel expense review template for documenting results. They also link to sampling and analytics tools for testing at scale.
