How to register as a Massachusetts vendor, step by step
These are the steps as the state describes them, in plain words. The portal may word things differently, and it can change, so keep the official page open beside you.
- On the COMMBUYS sign-in page, choose Create Your Supplier Account under Company Registration.
- Enter your tax ID (EIN; SSN is allowed for US sole proprietors, not for international vendors), company name, company email and country.
- Complete the rest of the supplier registration in COMMBUYS.
What to have ready before you start
Registration goes faster when the basics are in front of you. For Massachusetts, gather:
- Your legal business name exactly as it appears on your tax records, and any trade name you use.
- Your federal Employer Identification Number (EIN), or a Social Security number for a sole proprietor, since the state uses it to match you for payment.
- A business address, a phone number and an email address that someone reads every day; bid notices and questions from buyers go there.
- A short list of what you sell, so you can choose the matching the state's own commodity codes codes in one sitting.
- EIN (or SSN for US individuals) to create the supplier account
Does it cost anything to register in Massachusetts?
No fee is stated on the official pages we read: No fee stated on the official page. Be careful with outside services that offer to register you for a price. The state's own portal is where registration happens, and Massachusetts does not require you to use a paid middleman to sell to its agencies. Some separate things can cost money, such as a notary for a form, a professional license, insurance or a bid bond on construction work.
Which commodity codes does Massachusetts use?
Massachusetts matches vendors to bids with the state's own commodity codes. The state uses its own list of commodity or service codes. Choose every code that truly matches your work, because those codes decide which bid notices are emailed to you. If you also want federal work, you will need NAICS codes for SAM.gov; our free NAICS code lookup and the guide what a NAICS code is help you pick them.
Cities, counties and school districts in Massachusetts
Cities, counties and school districts usually run their own purchasing and bid lists, so registering with the state does not put you on every local list.
Large local governments in Massachusetts include Boston, Worcester. Each one usually keeps its own vendor list and posts its own bids, so register with the ones you want to sell to as well.
EasBid reads many of these local sources together with the state's, so one search shows state and local bids side by side.

Tips for your first Massachusetts bid
- Read the whole solicitation before you price anything; the due date, the question deadline and the submission method are usually on the first pages. Our guide on reading a solicitation shows what to look for.
- Ask questions in writing before the question deadline. Answers are usually posted as an addendum that every bidder can see.
- Check whether the bid needs a license, insurance certificate or bond, and get those started early.
- Submit through the channel the notice names, COMMBUYS or otherwise, and leave a day of margin; late bids are normally rejected.
- Whether you win or lose, ask for the award results. They show the winning prices and help you price the next one.
