  • Oversee W-9 collection, 1099 preparation, and sales/use tax compliance on applicable purchases.
  • Track and report key AP metrics, including invoice cycle time, on-time payment rate, aging, and processing bottlenecks, surfacing trends and escalating risks to management.
  • Design and enforce internal controls and segregation of duties to meet company policy, regulatory, and audit standards, support internal and external audit requests, and drive process improvements and AP and payment system implementations, upgrades, and integrations.
  • Partner cross-functionally with Procurement, Treasury, and Finance to improve procure-to-pay workflows, and provide day-to-day guidance and mentorship to AP staff.
