Which federal agencies award the most contracts?

The Department of Defense is the largest contracting agency, followed by Health & Human Services, the General Services Administration, Department of Energy, and NASA. Together they account for the vast majority of federal procurement spend.

How do I find contracts from a specific agency?

Click any agency in the directory to drill into its sub-tier offices, contracting vehicles, and active solicitations. Inside SamSearch you can further filter by NAICS code, set-aside type, and dollar threshold.

How often is agency contract data updated?

SamSearch syncs with SAM.gov and federal data sources hourly for new solicitations and daily for award history, so you see opportunities as soon as they are posted.

What is the difference between an agency and a sub-tier agency?

Top-level agencies (e.g., Department of Defense) are parent organizations. Sub-tier agencies (e.g., Army, Navy, Air Force) are the divisions that actually issue solicitations and award contracts under the parent department.

Can small businesses compete for contracts from any agency?

Yes. Most agencies have small business goals mandated by the SBA. Many solicitations are set aside exclusively for small businesses, 8(a), WOSB, SDVOSB, or HUBZone firms. SamSearch lets you filter by set-aside type to find the opportunities your business qualifies for.
