About Purchase Orders

Suppliers can receive POs from their Coupa-based customers via the CSP, cXML, or email/HTML.

Once you've got your catalog items into Coupa, you'll need to be able to receive purchase orders from users who want to buy your stuff. To make this process as effortless as possible, Coupa offers several ways of receiving invoices for suppliers of all sizes:

Coupa Supplier Portal

Create invoices directly from purchase orders on the Coupa Supplier Portal for free. This is the most comprehensive way to manage your interactions with Coupa. This method is ideal for suppliers with low to medium volume purchase orders and invoices, or who want to view all transactions from their customers who use Coupa in one place.


Tighter integration with Coupa allows you to receive purchase orders from Coupa. If you have a punchout, this is a natural choice. This is suitable for suppliers with a high volume of purchase orders, or those who automate their PO handling.


HTML-based purchase orders via email are for suppliers who lack the volume or resources to justify implementing an automated solution.
