• 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

• Familiarity with subscription billing platforms is a strong plus.
• Solid understanding of indirect tax regulations (sales & use tax, VAT) as they relate to invoice content and timing.
• Experience working cross-functionally with engineering and product teams on invoicing automation projects.
