Coupa Supplier Portal (CSP)
Your one-stop platform for sourcing, contract lifecycle management and supplier information
What is the Coupa Supplier Portal (CSP)?
The Coupa Supplier Portal (CSP) is a secure, easy-to-use platform that simplifies how we work together. It allows our suppliers to manage company information, access sourcing opportunities, submit bids, and provide quotes all in one place.
By using the CSP, suppliers benefit from greater visibility, improved communication, and faster, more efficient engagement with OCS.
