Prevent single‑point failures by separating preparation, approval, and payment release. Require two approvers for high‑risk changes, such as off‑cycle payouts, banking updates, and retroactive adjustments. Log every step with user, time, and reason codes. Regularly rotate responsibilities to reduce collusion risk. Training and shadowing programs keep backups ready for vacations or unexpected absences without compromising control.

Build rules that flag unusual variances by employee, department, and country, comparing current values with rolling baselines. Validate bank account formats, check payment files against schema, and verify totals before releasing funds. Machine‑assisted review accelerates cycles while catching edge cases humans miss. Tune thresholds gradually, and always provide override workflows with documented rationale and post‑run reconciliation checks.
