Register for the CSP

Create an account at supplier.coupahost.com, get an invitation email from your Coupa customer, forward an invitation to a peer, or create an account from a PO email.

You can register for the Coupa Supplier Portal (CSP) through:

  • A customer-created invitation
  • A self-created registration
  • A purchase order (PO) email
  • A forwarded invitation from a coworker

The following table provides more detailed information about the benefits and considerations for each method.

Method Benefits Considerations
Customer-created invitation
  • You get a custom-invitation with specific instructions and a proactive message from your customer.
  • When you accept the invitation and create your account, you are automatically connected/linked to the customer who invited you.
You have to wait for your customer to send the invitation email. This means that you might not get invited due to your customer forgetting or not having the time to send the invitations to all their suppliers.
Self-created registration
  • You can create your account or accounts ahead of time
  • You can add multiple users
  • You can set up your login preferences
  • You can update your profile more quickly
  • You need to connect manually to your customers in Coupa. Let your customer know that you registered and you want to connect with them.
  • Customers can connect with you through their Supplier Portal Directory, or by sending an invitation email to any of the CSP supplier users on the account. However, if you are invited using a different email, that email can log in but will have to merge with the account that was set up ahead of time in order for all the supplier users to be on the same account and linked to the customer.
Purchase order (PO) email
  • Your customer does not have to proactively manage invitations and reminders for you to get connected through the CSP.
  • You can create a CSP account without requiring an invitation if you use Supplier Actionable Notifications (SAN), InvoiceSmash, or other PO methods.
  • As PO emails are a frequent communication channel between you and your customers, you have more opportunities to create a CSP account and enjoy its benefits.  
  • None
Forwarded invitation from a coworker
  • You can easily invite others within your organization to the CSP by forwarding them your PO email notification or by sending them an invitation from the create account page.
  • You end up with the right supplier user(s) linked to and transacting electronically through the CSP with less work.
  • You can forward the invitation only to email addresses with the same domain. However, this ensures more built-in security.

With all methods, you need access to the email address you are going to use for the account.

Your CSP account is based on a specific email address. If you use an email address different from the one your Coupa customers have on file for you, you cannot connect with them until you give them the email address or create a CSP account with that email address.

How to register for the CSP through different methods

The following sections provide details instructions to register via your prefered method:

Tip

If you do not receive your invitation email, check your spam folder.

Forwarded invitation

You can invite others to the CSP by:

  • Forwarding them your PO email notification with the Create Account button
  • Clicking on the Forward This button in your CSP invitation email, or by
  • Sending them an invitation from the create account page
Warning

You can forward the invitation only to email addresses with the same domain.

An invitation to the CSP is sent to the email address that you specified.

When the invited user clicks on the Join Coupa button in the email, the user is directed to create an account in the CSP. 

If the user is already linked to the CSP or tries to create an account from an expired invitation, the user is directed to the Register / Login page where a red message bar displays the following: "Your invitation has expired or already been activated."

Warning

Invitations to the CSP expire after 30 days.
