Go to the State of New Hampshire Online Vendor Registration site (apps.das.nh.gov/vendorregistration). You can also get there from the Vendor Resource Center page.
Complete the online registration and submit it.
Watch your email. The state says you "will receive an e-mail update with their vendor number within 1 to 3 business days."
If you can't register online, download the Vendor Application package (Vendor Application and Alternate W-9). Fax it to (603) 271-2700 or mail it to Bureau of Purchase and Property, 25 Capitol St, Room 102, Concord NH 03301.
If you haven't already, register with the Secretary of State and make sure you are in good standing before you bid on anything you might win.

What to have ready

A valid email address. The online registration requires one.
Legal business name, FEIN (or SSN for a sole proprietor), address and contact info. The official pages don't list every field, so treat this as typical rather than confirmed.
A W-9. If you use the paper route, the state asks for its "Vendor Application and Alternate W-9."
Registration with the NH Secretary of State, if your business type requires it. The state says you "may be required to register with the Secretary of State" and must be "currently registered to do business and in good standing" to be awarded a contract.
Bank details, if you want direct deposit. The State Treasury handles direct deposit.
