Frequently Asked Questions
What professional services contracts does the federal government award (NAICS 54)?
NAICS sector 54 (Professional, Scientific, and Technical Services) is one of the largest federal contracting sectors, covering IT consulting, engineering, R&D, management consulting, architecture, legal services, and accounting. Major buyers include DoD, DHS, VA, and civilian agencies across all categories.
How do I find federal contracting opportunities?
Federal contracting opportunities are posted on SAM.gov (System for Award Management). You can search by keyword, NAICS code, set-aside type, agency, and response deadline. FedOps aggregates and enriches SAM.gov data daily so you can filter and track opportunities in one place.
What is a set-aside in federal contracting?
A set-aside is a procurement reserved for a specific category of small business. Common set-asides include SDVOSB (Service-Disabled Veteran-Owned), 8(a), WOSB (Women-Owned), HUBZone, and Small Business. Only businesses that meet the eligibility requirements can bid on a set-aside contract.
How do I register to bid on federal contracts?
You must register your business in SAM.gov (sam.gov), which is free. You'll need a DUNS/UEI number, NAICS codes for your business, bank account information for electronic funds transfer, and applicable certifications (8(a), SDVOSB, WOSB, etc.) if bidding on set-asides. Registration is renewed annually.
