Purchase Orders

The Purchase Order (PO) is Metro's approved purchasing method. A PO issued from Metro’s Oracle iProcurement system streamlines the standard transactional process by requiring departmental requestors to be specific when ordering, systematically verifying funding availability, permitting suppliers to deliver as requested, and when matched to the supplier’s invoice, enables Metro to pay within 30 days – 15 business days if an approved Small Business (SBE) or Service Disabled Veteran-owned (SDV) Business.

The PO process is a series of actions in which different participants play important roles. The chart below provides an overview of who participates at each point in the process.

  • The departmental requestor enters funding and ordering information
  • Departmental purchaser attaches all required documentation electronically
  • Procurement staff uses contracts where present or competes the purchase
  • Suppliers perform as pledged and deliver items per the PO and Standard Terms and Conditions
  • Departments verify and receive items shipped by supplier
  • Supplier’s shipment complies with PO, allowing supplier to invoice
  • Supplier sends invoice as directed on PO (Generally, Payment Services)
