What it is

Coupa Supplier Portal is a free online tool for suppliers working with organizations that use Coupa. Depending on each customer's configuration, suppliers can view purchase orders, manage catalogs, submit invoices and advance ship notices, and check transaction status. Invoices can go through the portal, Supplier Actionable Notifications, cXML, or email/PDF when the customer uses Coupa invoicing. Suppliers can create hosted catalogs or cXML punchout catalogs, and invoice validation and history include checks for country-specific requirements. When customers use Coupa Pay, suppliers can accept digital checks; listed payment methods also include domestic or global bank transfers. The CSP REST API can retrieve invoice and purchase order information for other systems, uses OAuth 2.0, and is available by request or with a custom subscription. Coupa Verified is an optional subscription for verifying supplier contact and business details, with a badge and priority in supplier searches. Supplier support is available by agent chat 24x5 or email.
