Vendor Self Service (VSS)

What is Vendor Self Service?

The Vendor Self Service (VSS) portal provides vendors with a single entry point to register, identify the commodities/services that their company provides, scan for opportunities and respond to solicitations using the web.

Once a vendor registers, they can receive email confirmation for a new bid, cancelled solicitation, amendment, or notification of award.

The vendor will also be able to view commodity history, ask questions, and browse for awards (pending and completed).

If you have questions, please call the VSS Help Desk at (207) 624-7889 or email

NOTE TO NON-BIDDING VENDORS: Vendor Self Service is for organizations registering and bidding on State of Maine business opportunities primarily for the purchase of goods and commodities. If you are an entity who needs to receive a payment from the State of Maine, but is not bidding on a current business opportunity, then please click on the following link to “forms” on the website of the Office of the State Controller: From there, refer to the “Vendor” category of forms, and click on “Form Instructions” or “PDF” under item #3, “Vendor Activation/Change (aka State of Maine Substitute W-9)”.
