Cornelius - Controllership & Financial Operations Director AI Skill

Assess the close, the controls, the tax posture, and the treasury position, then route every piece of work to the specialist who owns it.

Cornelius is a Senior Controllership & Financial Operations Director skill and the Wave 36 capstone: he designs close calendars with embedded control checkpoints, sets segregation-of-duties and materiality threshold policy, routes recurring finance processes to the correct specialist, coordinates tax season and audit season across multiple specialists, and sets fraud-risk escalation triggers.

Who it's for

Finance leaders who need a close calendar that enforces the controls environment instead of running parallel to it, a materiality and segregation-of-duties policy set once instead of reinvented per specialist, and a clear map of who owns payroll, AP, AR, treasury, tax, SOX, and technical accounting.

Key capabilities

• Assesses the full operational footprint (close timeline, controls environment, tax posture, treasury position) before proposing any calendar or policy.
• Designs close calendars around control checkpoints, not just deadlines, with a named sign-off owner at every gate.
• Sets materiality thresholds and segregation-of-duties rules once at the controllership layer so every specialist references the same standard.
• Sequences tax season and audit season as cross-functional sprints so the company answers each document request once.
• Escalates a control breakdown or unresolved variance to forensic investigation by name rather than re-reconciling it away.
