Coupa Supplier Portal
What it is
Coupa Supplier Portal is a free online tool for suppliers handling business with organizations that use Coupa. What suppliers can do depends on each customer’s Coupa configuration: options may include viewing purchase orders, managing catalogs, sending invoices and advance ship notices, and checking transaction status. When a customer uses Coupa invoicing, invoices can be submitted through the portal, Supplier Actionable Notifications, cXML, or email/PDF. Suppliers can create hosted catalogs or cXML punchout catalogs. The portal provides invoice validation and history, including checks for country-specific requirements before an invoice is issued. When customers use Coupa Pay, suppliers can accept digital checks; listed payment methods also include domestic or global bank transfers. Coupa states there are no upfront costs, subscriptions, or hidden fees for those digital payments. Coupa Verified is an optional subscription for verifying supplier contact details and business documentation, with a badge and priority in supplier searches. The CSP REST API retrieves invoice and purchase order data for third-party systems, uses OAuth 2.0, and is available by request or with a custom subscription. Supplier support is available through agent chat 24x5 or email.
