Subcontracting opportunities: NAICS 561920, Convention and Trade Show Organizers

Primes? with subcontracting plans in 561920

Most plan contracts first.

Most large primes have no profile here: find them on their own websites, where they post supplier portals and small business liaison contacts.

Recent subcontracts to small businesses

Of the 297 most recent subcontracts primes reported in the wider 5619 group (other support services), dated Jul 29, 2025 to Sep 29, 2026, 138 went to small businesses, worth $63.6M. The table shows 40, newest first, from Sep 29, 2026 back to Feb 10, 2026. It takes no more than 3 from any one prime contract, so a single large program doesn't fill it.

Primes report subcontracts to USAspending.gov months late, so the newest report we read is from Sep 29, 2026. USAspending files each subcontract under its prime contract's NAICS code, not the subcontractor's own work, so some of these jobs look unrelated to 561920.

Which agencies

How to win subcontracts with these primes

1. Register in the prime's supplier portal. Most large primes have one, usually under “supplier diversity” or “small business programs” on their website. Buyers search it when they need a subcontractor, so list your NAICS codes, certifications and past work.
2. Contact the small business liaison officer. Every prime with a plan names someone to run it. Find them through the supplier portal, or for defense primes in DoD's prime contractor directory. Send a one-page capability statement that names the contracts and agencies you can support.
3. Watch SBA's SubNet. Primes post subcontracting solicitations and sources sought notices on SubNet.
4. Be easy to vet. Keep your SAM.gov registration active and check that you count as small under 561920's size standard. Certifications such as 8(a), HUBZone, WOSB and SDVOSB count toward the prime's goals, which makes you more valuable to them.
5. Get free help. APEX Accelerators introduce small businesses to primes and run matchmaking events. Our guide to becoming a government subcontractor covers the rest.
