  • All vendor invoices (not quotes) are to be sent directly to invoices [at] from the vendor. The PO number should be referenced on the invoice for accurate and timely processing.
  • All inquiries or questions are be sent to accountspayable [at] Please do not forward inquiries directly to Accounts Payable staff.
  • Standard payment terms are net 30 for all vendors, unless alternate terms are negotiated and approved by the Executive Director of Purchasing and Policy Compliance.
  • Do not submit multiple copies of the same invoice.
  • All vendor payments will have standard delivery of US Mail, unless given approval for pickup. Checks will only be released to the person who initiated the PO or the person authorized by a letter on the vendor’s letterhead.
