# Error: Your company or user account does not exist on [buyer] site.

## Symptom

Why do I receive the below message when accessing the Ariba Proposals and Questionnaires dashboard?

Your company or user account does not exist on \[buyer\] site. \[buyer\] may have disabled the automatic synchronization of additional users from your organization, or there may have been an error when synchronizing your Ariba Commerce Cloud account with \[buyer\] site.

## Cause

There are a few reasons why you may receive this error message:

- If you have recently changed your username, you may have broken the connection between your account and your customer's site.

- Your supplier user profile inside the customer's site, which is connected with your account, has been unapproved by the customer.

- Another user within the same Ariba account has connected with the client, but your own user account is not connected yet. Since you are part of the same overall account, you can see the client's name on the dashboard, but to access the customer's documents your user account also needs to receive it's own invitation email from said customer.
- The same email address is already registered under another company. This may be an organization where the user no longer works, or one that has since changed its name.
- The username in your account differs from the one linked to the buyer's site. E.G. Your account User ID is: customer@ariba.com but the one connected to the customer's site is Customer@ariba.COM (has capital letters in it).

## Resolution

- If you recently changed your username, please change the username back to what it was originally or contact[SAP Ariba Customer Support](https://support.ariba.com/item/view/174605) to establish the connection again.
- Otherwise, you will need to contact your customer directly and ask them to send you a new invitation link to connect with their site, or to reactivate your supplier user profile (if deactivated).
- The outdated account should be unlinked. The buyer will then need to send a new invitation so the user can be properly re-associated. Once completed, the user’s status will be updated from “Private” to “Public” in the buyer’s directory.
- [Edit your account User ID](https://support.ariba.com/item/view/KB1240900) so it matches with the same one that was linked with the customer.
