What's Next for COMMBUYS?

Working closely with the Office of the State Comptroller, the Operational Services Division (OSD) is actively planning Phase II of the COMMBUYS rollout, an interface with the Massachusetts Management Accounting and Reporting System (MMARS).

Punch-Out Catalogs: Streamlining the Purchaser Experience

Purchasing through COMMBUYS has never been easier with online seller catalogs or Punch-Outs. After selecting your items in one of the available seller Punch-Out catalogs, selections are pulled back into COMMBUYS and summarized on your requisition.

Log in to COMMBUYS and select the shopping cart icon at the top of your navigation dashboard to get started. Select the vendor drop-down menu to display available Punch Out catalogs. Currently, the following seller catalogs are available:  A&A Industrial Supply/Albeco Fasteners (FAC76); Fastenal (FAC76); Ferguson (FAC76); F.W. Web (FAC76); G.A. Blanco and Sons (OFF32); Government Scientific Source (HSP34); Grainger (FAC76); Granite City Electric (FAC76); Graybar (FAC76); Home Depot (FAC76); MSC Industrial Supply (FAC76); Motion Industries (FAC76); New England Office Supply (OFF36); NorthEast Electrical (FAC76); VWR International (HSP34); and W.B.

*Please note: While some Statewide Contract sellers may not yet have Punch Out catalogs, purchasers may still make purchases from those businesses using a line item catalog in COMMBUYS.  

Buyers may find additional guidance for using Punch Out catalog functionality through the Punch Out Job Aid pdf format of Purchase from a Vendor Online (Punchout) G2B Catalog

Enabling Complete and On-Time Responses to Bids in COMMBUYS

The COMMBUYS Help Desk often receives a high volume of calls from vendors seeking assistance as they submit bid responses. As a best practice, purchasers should set bid opening dates/times that fall on a Tuesday, Wednesday, or Thursday with a deadline of 4:00 p.m. or earlier, periods when call volume is generally lower and Help Desk staff are able to provide the level of support sellers need.


OSD strongly discourages assigning Friday at 5:00 p.m. as a bid opening date/time.
