Solution: Do better work, faster with Confirmation
The Citi Services and Thomson Reuters Confirmation teams designed a robust, scalable integration centered on performance, controls, and multi-region deployment. The Thomson Reuters API was integrated directly into Citi’s internal workflow system to support standardized confirmation handling.
A phased rollout enabled continuous improvement across North America, Africa, Europe, LATAM, the Middle East, and Asia, supporting predictable expansion and consistent execution across regions.
Outcomes: Closing the audit-response gap
The API-driven operating model has delivered significant benefits for Citi Services. A single, standardized confirmation process is now used globally, enabling consistent execution across markets. Increased automation has reduced manual effort, supporting faster cycle times and stronger performance, while consistent tracking and reporting have enhanced global visibility and audit readiness.
The integration has also enabled rapid and predictable onboarding into new countries, supporting expansion while maintaining consistency. As a result, Citi Services has enhanced service delivery during audit season, improving the experience for auditors and clients alike.
By deploying API-driven automation across numerous markets, Citi Services is establishing a high benchmark for digital transformation in audit response. This initiative demonstrates leadership in standardization, speed, and user experience, proving that modernization can be both rigorous and globally scalable.
