Purchase Orders and Invoices

Purchase Orders

It is the policy of Children’s National Hospital to purchase all supplies and services through the Supply Chain Department. Purchase arrangements or commitments made other than by Supply Chain may be considered non-binding. It is the sole responsibility of the Supply Chain Purchasing Department to make purchase commitments which finalize the terms of procurement agreements with suppliers. These terms – which include price, packing, shipment, delivery, inspections, insurance, payments, waivers, and legal compliance – are finalized through a signed purchase order (PO) which legally commits Children’s National.
