Coupa is a comprehensive T&E solution designed to help businesses capture, manage, validate, and analyze expenses across the organization. Through automation and consolidated reporting, Coupa captures expenses from sources like expense reports, purchasing cards, and travel bookings.

Coupa is a valuable source because it can help significantly reduce the time and effort required for finance teams to ensure compliance, review/approve expenses, and identify suspicious spending.

Our integration to Coupa fully supports this change by having a new integration form available in every LeanIX workspace by default.
