How to Become a Vendor

From the Vendor Resource Center page click the link at the top titled "Online Vendor Registration". You will need a valid e-mail address in order to complete the Online Vendor Registration.

If you do not have an e-mail address, you may still manually fill out a "Vendor Application" package. You may download this Vendor Application and Alternate W-9 The Vendor Application and attachments may be FAXED to us at (603) 271-2700.  Our mailing address is: Bureau of Purchase and Property, 25 Capitol St, Room 102, Concord NH 03301. 
As an authorized vendor to the State of New Hampshire, you have certain obligations, responsibilities and rights as are spelled out on the reverse of the Purchase Orders, "Contract Terms and Conditions", "Purchasing Rules Manual" and the "RSA's" (Revised Statutes Annotated).

You may be required to register with the Secretary of State. A bid award, in the form of a Purchase Order or Contract will only be awarded to a vendor who is currently registered to do business and is in good standing with the State of New Hampshire.  Please contact them at 271-3244 to determine your status with them or go to their web page located at:
