COMMBUYS Registration Instruction

If you plan to do business with the Commonwealth of Massachusetts you are required to register on COMMBUYS before applying for any funding opportunity.

Registration Required: While you may previously have been registered as a seller in Comm-PASS, no vendor registration was transferred to COMMBUYS, so you must now register as a seller in COMMBUYS.

To assist you in the registration process, the Operational Services Division (OSD) has provided you with a series of COMMBUYS job aids and on-line learning videos for your use as you transition to COMMBUYS.

COMMBUYS registration is easy! It takes just three simple steps:

1. Go to the COMMBUYS landing page at www.COMMBUYS.com.
2. Select the first link titled REGISTER and complete registration. There is no cost.
3. PLEASE NOTE CHANGE: You must register on COMMBUYS and select the United Nations Standard Products and Services Code (UNSPSC) 00-00-00 for all Grants in the Commonwealth. If you have already registered, please make sure you add the UNSPSC code to your registration.

Once you have registered, OSD will be able to link your agency's contract to the registration, which will allow you to get direct receipt of electronic POs or quote requests from the system.

Please note: Applicants will be required to be specify an Administrator as part of the registration process. COMMBUYS will confirm that the Tax ID entered does not already exist in the system. If the Tax ID is already in use, you will need to follow-up within your own agency to a obtain access to COMMBUYS. More detailed instructions are provided in the job aid if this applies to your agency.

We look forward to welcoming you to the COMMBUYS community. If you have any questions or concerns, contact the COMMBUYS Help Desk at COMMBUYS@state.ma.us or contact them during normal business hours (8AM – 5PM Monday – Friday) at 1-888-627-8283 or 617-720-3197.
