Can we have more than one user access the Coupa Supplier Portal (CSP)?

Only one person should register for the CSP. This person will be the administrator of your CSP account. The administrator can then invite multiple people to join. In some cases, you may find you have multiple customers using Coupa and therefore have multiple registrations on the CSP. Coupa provides a 'merge function' to help manage the account. Please see the Coupa administration guides on the Coupa website.
