Frequently Asked Questions

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.
