Procurement relies on the AFS

AFS's Resource Management, Finance Customer Service & Disbursement Solutions and Procurement Organization is a unique blend of functional responsibilities that include:

  • Purchasing services
  • Accounts payable
  • Customer support services

While each of these departments can operate independently, they are a part of an end-to-end process intent on delivering high quality, back-office infrastructure support across Nationwide. At the core of our PTP model is the ability to process a high volume of transactions in a consistent, effective and cohesive manner.
