Selling to the US federal government is gated by registration and contract vehicles. Nothing happens until you’re registered on SAM.gov, and most recurring sales flow through schedules like the GSA Multiple Award Schedule. This guide covers the mandatory first steps, the route for each sector, the credentials you’ll need, and how Sales Source gets you registered and selling.

A portal or framework is the compliant route a public body uses to buy. Get registered on the right one and you become buyable; rely on relationships alone and you may never even be invited to bid.

Key takeaways

  • US federal procurement is the largest market on earth - and gated by registration and contract vehicles.
  • Nothing happens until you have an active SAM.gov registration (UEI + CAGE code), renewed annually.
  • Most recurring sales flow through vehicles like the GSA Multiple Award Schedule, which you can apply to at any time.
  • Map your offering to NAICS codes, use any small-business set-asides, and get CMMC certified for defense work.

How public procurement works in the United States

Every country runs its own system. Here’s the lay of the land in the United States, then the named route for each sector.

Find your route to market

The right route depends on what you sell and who you’re selling to. Choose your sector to see the named portals and frameworks, exactly how to register, the credentials buyers expect - and a direct link to each official site.

Frequently asked questions

How do I start selling to the US federal government?

Register your entity on SAM.gov - it’s free, requires a Unique Entity ID and CAGE code, takes several weeks, and must be renewed annually. You must have an active registration before you can submit any federal bid.

What is a GSA Schedule?

The GSA Multiple Award Schedule is a government-wide catalogue of pre-negotiated commercial products and services. Unlike most vehicles you can apply at any time, and once awarded, agencies can buy from you directly or through eBuy.

What is CMMC and do I need it?

CMMC (Cybersecurity Maturity Model Certification) is now mandatory for Department of Defense contractors and their subcontractors, phasing in from late 2025. For defence work it is a pass/fail gate, not optional.

Are there easier routes in for small businesses?

Yes. A large share of federal work is reserved through SBA programs and set-asides such as 8(a), HUBZone, WOSB and SDVOSB, and subcontracting to a prime is a practical way to build the past performance agencies look for.
