Selling to the State of New Hampshire

How a company registers as a supplier with the State of New Hampshire, the state's certification programs, and where to get help in New Hampshire, with the official sources. Federal registrations such as SAM.gov are in the federal guides.

NH Department of Administrative Services (DAS), Division of Procurement and Support Services, Bureau of Purchase and Property

How to register

1. 1Start with the NH Department of Administrative Services (DAS). Its Bureau of Purchase and Property manages most State purchases of goods and non-construction services for NH state agencies, according to the NH APEX Accelerator.
2. 2Register online through DAS's Online Vendor Registration (apps.das.nh.gov/vendorregistration/). DAS's vendor FAQ says a valid email address is needed. Bid notices and purchase orders go to that address, so DAS asks for a general company email rather than a person's own. Only one contact is allowed per vendor.
3. 3Registration is free. DAS's vendor FAQ says there is no registration fee.
4. 4If your company has no email address, fill out the DAS Vendor Application and Alternate W-9 form. Fax it to 603-271-2700 or mail it to the Bureau of Purchase and Property, 25 Capitol Street, Room 102, Concord, NH 03301.
5. 5Choose your NIGP (National Institute of Governmental Purchasing) codes. DAS says these codes match your goods or services to solicitations. For more than 100 codes, DAS offers an Excel code list to email back with your vendor number and tax ID.
6. 6Expect a vendor number about 3 business days after a successful online application, according to DAS.
7. 7Register with the NH Secretary of State, Corporate Division, before any contract award. The DAS Vendor Application says this 'MUST be done prior to the awarding of any contracts' (Corporate Division: 603-271-3244). DAS's FAQ says bidding without a vendor number is allowed, but contracts go only to vendors registered and in good standing with the Secretary of State.
8. 8For electronic payment (ACH, Automated Clearing House), contact the NH Treasury at ACHProcessing@treasury.nh.gov after vendor registration is complete, as the Vendor Application says.
9. 9Watch for the State's new Supplier Portal. In a March 13, 2026 notice, DAS said a Supplier Portal is 'expected to launch later this year' for supplier numbers, company updates, ACH details, invoices, bids and proposals. DAS will move existing vendor records into it. It asked existing vendors to send a contact name, business phone and business email (which becomes the permanent portal user ID) to prch.web@das.nh.gov.
10. 10Check current State bids on the DAS bids page (apps.das.nh.gov/bidscontracts/bids.aspx). Watch individual agency websites too. NH APEX says Requests for Proposals (RFPs), Requests for Qualifications (RFQs) and Requests for Information (RFIs) can come straight from a state agency, and some are posted in newspapers.
11. 11For the University System of New Hampshire (UNH, Keene State, Plymouth State and others), check USNH Purchasing & Contract Services, which buys separately.
12. 12For help, contact DAS at prch.web@das.nh.gov or (603) 271-2201 (Monday to Friday, 8:00 a.m. to 4:00 p.m.). For free help, contact the NH APEX Accelerator at govcontracting@livefree.nh.gov. Its free Bid Match Program sends daily bid notices that match your products or services.
