# New Subcontractors Join Prime Bidder Lists

For a new subcontractor, a practical route onto a prime contractor’s working bidder list is to submit complete, timely responses to invitations to bid (ITBs)—the step the source identifies as most directly within a subcontractor’s control. The guidance also recommends maintaining current SAM and SBA DSBS profiles, attending pre-bid meetings and industry days, building relationships with primes, and communicating capabilities concisely. GovSeek is cited as a free teaming-partner matching option; no specific solicitation, contract, or response deadline is identified.

- Companies seeking subcontract work should prioritize complete, on-time ITB responses and keep their SAM and SBA DSBS profiles current.
- Attending pre-bid meetings and industry days, alongside consistent relationship-building and clear capability messaging, can help new firms become known to prime estimators.
- GovSeek may provide an additional free channel for finding teaming partners; the signal does not identify a particular opportunity or guarantee placement on a prime’s bidder list.

### Key Quotes
> The lists a prime actually bids from get built in three places: subs we've watched perform, subs our estimators already know, and people who responded to an ITB completely and on time. As a new sub, that third one is your door, and it's the one you control.
