• Month-End Close Support: Own AP close activities including accruals, vendor statement reconciliations, and aged payables review. Ensure completeness and accuracy of AP balances across all entities for month-end reporting
• Systems & Process Improvement: Optimize AP workflows in NetSuite and Zip, identifying automation opportunities to reduce manual effort and improve accuracy. Lead or contribute to system implementations or upgrades as the company scales
• Global AP Operations: Support AP processes across US and international entities (UK, Ireland, Poland, Germany), including multi-currency payments, VAT considerations, and compliance with local payment practices
• Audit & Compliance Readiness: Maintain audit-ready AP documentation, support external auditors with AP-related requests, and contribute to the development of internal controls aligned with SOX or equivalent frameworks
• Cross-Functional Collaboration: Partner with FP&A on cash flow forecasting, with Legal on contract and vendor onboarding requirements, and with business stakeholders to ensure spend is appropriately budgeted and coded
