Unison Marketplace is able to contact and provide registration assistance for any Seller.  Unison Marketplace’s Sourcing team is able contact any Sellers listed as Suggested Sources.  Additionally, if a suggested source email address is provided, they will receive an automatic notification.


If a Seller was not listed as a Suggested Source when the buy was posted and you would like to invite them to bid, provide their contact information to your Account Manager, and they will then work with the Sourcing team to provide support to that Seller.
