Ask your customer to send you an invitation to the CSP. The invitation email has two buttons:

1. Join Coupa: On the tab that opens, create and confirm a password.
   1. Accept the Privacy Policy and Terms of Use.
   2. Click Get Started to create an account for the CSP.
2. Forward this invitation:
   1. On the tab that opens, click the Forward this to someone link.
   2. Enter their email and click Forward.

The links on the invitation email to the CSP expire after 30 days and are invalidated if the inviter's account is deactivated.

If a customer sends an invitation to an inactive supplier user on CSP, then the invitation will be rejected during processing. Inactive suppliers are suppliers that are already registered in Coupa but their accounts appear as inactive.

For more information see Manage Users.

If a customer sends an invitation to an inactive supplier user on CSP, then the invitation will be rejected during processing. To resolve the issue, either:

• The customer has to reach out to the supplier and ask the supplier to reactivate their account on CSP. Once the account is activated, the customer has to resend the invite to the supplier.
• The customer can send the invite to another email address for the same supplier.
