The Coupa Supplier Portal (CSP) is a free tool for suppliers to easily do business with their customers who use Coupa. The CSP makes managing customers and transactions easy. Depending on your customer's specific Coupa configuration, you can manage content and settings on a customer-by-customer basis, including viewing purchase orders, setting up delivery methods, creating catalogs, sending invoices and advance ship notices (ASNs), checking the status of transactions, and more.
Note
You can log in to the CSP at CSP Login.
The CSP user guide is available as a PDF in several languages. While the PDFs do not contain the latest updates, they are a valuable resource. For the latest updates, see the HTML pages.
