The vendor portal is a secure website that allows external stakeholders to access for purposes of communicating commercial offers. You can publish Requests for material or services and Vendors can submit offers. The purchasing agent can compare the offer received and choose the one deemed best or more cost effective. The offer is converted into a purchase request that, based on the approval workflow, is transformed into a purchase order, which is transferred from NOW to the portal. From here the vendor approves the order and processes it. Upon fulfillment the vendor can also send the detailed list of what he is going to deliver in the form of an Advanced Shipped Notice (ASN).
