Questions

How many NAICS 541330 sources sought notices are open?

On October 24, 2026 there were 45 open sources sought notices for NAICS 541330 on SAM.gov, and 574 in the last 12 months. BidFox updates this page every morning.

What is a sources sought notice?

It is a request for information: the agency wants to know which companies can do the work, and whether enough small businesses exist to set the contract aside. It is not a solicitation, so there is no award from it directly.

Should I answer a sources sought notice?

Usually yes, if the work fits you. A short capability statement that answers the questions asked is enough. If two or more capable small businesses respond, the contracting officer often has to set the solicitation aside for small businesses.
