What Is the Difference Between grants.gov and SAM.gov?
The Simple Version
Think of it this way:
- grants.gov = the government is giving money away to organizations that qualify
- SAM.gov = the government is buying something and needs a vendor to sell it
Both are federal money flowing out of Washington. The difference is the mechanism and who qualifies.
grants.gov — Federal Grants
grants.gov is managed by HHS on behalf of all federal grant-making agencies. It lists every discretionary grant opportunity the federal government makes available — programs like:
- NIH research grants for universities and hospitals
- USDA rural development grants for small communities
- Dept of Education grants for schools and nonprofits
- EPA grants for environmental projects
- NEA/NEH grants for arts and humanities organizations
Who applies: Nonprofits, local governments, schools and universities, hospitals, tribal governments, research institutions, and (for some programs) small businesses.
Who does NOT typically apply: Large corporations, individuals (with some exceptions), for-profit businesses (unless the specific program allows it).
What you receive: A grant award — money given for a specific purpose. You are accountable for how you spend it (reporting requirements, audits) but you are not a vendor selling something.
SAM.gov — Federal Contracts
SAM.gov serves two functions: vendor registration AND contract opportunity listings. The opportunity database (formerly FedBizOpps/FBO) lists solicitations — the government needs to buy something and is asking businesses to propose a price.
Who responds: Any registered business — from a one-person consulting firm to a large corporation. Set-aside designations (small business, veteran-owned, women-owned) restrict some competitions to specific business types.
What you receive: A contract — a legal agreement to provide goods or services for payment. You're a vendor, not a grant recipient.
| grants.gov | SAM.gov Contracts | |
|---|---|---|
| Who it's for | Nonprofits, governments, schools | Businesses (any size) |
| What it is | Free money for a purpose | Paid work for the government |
| Application | Grant application package | Proposal or quote |
| Registration | grants.gov + SAM.gov | SAM.gov required |
| Key number | CFDA code | NAICS code |
| Competition | Often limited applicants | Open bidding |
| Reporting | Grant reporting required | Contract deliverables |
The Connection Between the Two
Here's what most people miss: SAM.gov registration is required for both. Whether you're applying for a grant or bidding on a contract, your organization must be registered and active in SAM.gov. This is a common stumbling block — organizations apply for grants through grants.gov and then discover their SAM.gov registration has lapsed.
Which One Is Right for You?
Choose grants.gov if:
- You are a nonprofit, school, government agency, or research institution
- You are seeking funding for a specific mission-driven purpose
- You don't have a product or service to sell the government
- You are willing to meet grant reporting requirements
Choose SAM.gov contracts if:

- You want to be paid as a vendor, not receive grant funding
- You are willing to compete for work through a bidding process
- You want to build an ongoing business relationship with federal agencies
