To make changes or modifications to an existing vendor profile, please use the Vendor Modification Request form by clicking the following link: http://procurement.columbia.edu/ap/vm/vendormaintenance.php

Please use this form to submit a modification and / or validation request to an existing vendor. Using this form is the most efficient way to modify/validate existing vendors. Please complete a separate form for each vendor you wish to modify / validate. However, you are able to request multiple modifications for a single vendor if applicable.

For questions and to check the status of a pending request, please e-mail vendormaintenance@columbia.edu.
