Invoices

Send invoices to your customers through Supplier Actionable Notifications, the Coupa Supplier Portal, cXML, or email/PDF.

Invoicing is an optional part of Coupa, so not all of your Coupa-based customers handle invoicing through Coupa. For customers who handle invoicing through Coupa, we offer several ways of receiving invoices for suppliers of all sizes:

Compliance as a Service

If your customer wants to use Coupa invoicing with Compliance as a Service, there are additional requirements to create your e-invoices if you use Supplier Actionable Notifications (SAN), the Coupa Supplier Portal, or cXML invoicing channels.

Supplier Actionable Notifications

Flip your incoming PO's into invoices right from the PO email. This is the easiest way to submit electronic invoices through Coupa. You can also acknowledge and comment on PO's right from the email.

Coupa Supplier Portal

Create invoices directly from purchase orders on the Coupa Supplier Portal (CSP) 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.

View invoices through the CSP REST API

The API allows you to retrieve CSP data. Using this API, you can retrieve all invoices in the CSP, and retrieve data for a single CSP invoice.
For more information see Coupa Supplier Portal REST API.

cXML

Tighter integration with Coupa allows you to send cXML invoices directly to Coupa. If you use cXML for purchase orders, this is a natural choice. This is suitable for suppliers with a high volume of purchase orders, or who automate their invoicing.

Email/PDF

Sending PDF copies of invoices through email are for suppliers who lack the volume or resources to justify implementing an automated solution. However, this method may not be allowed by all companies, so check with your customers prior to sending. 

Attachments

When attaching a document to an invoice, please make sure that the document is relevant and appropriate to the transaction. If you have attached a document in error and the invoice has been submitted to your customer on the Coupa Platform, please contact your customer and request for the file to be removed on your behalf.
Please provide the link to this article and specify the document number univocally. Your customer will contact Coupa support to carry out such a request in due time.
