• Identify and resolve invoicing discrepancies and tax mismatches; escalate complex issues to senior tax leadership as needed.
• Develop and maintain a library of invoice scenarios, edge cases, and exception-handling documentation.
• Support audit readiness by ensuring invoice archives are accurate, complete, and easily retrievable.
• Create training materials and conduct knowledge-sharing sessions for billing operations and customer-facing teams
