Grants vs. Contracts vs. Cooperative Agreements: Which Money Is Which

Federal money reaches organizations through two fundamentally different doors, and mixing them up sends people to the wrong websites writing the wrong documents for the wrong readers. A 1977 law — the Federal Grant and Cooperative Agreement Act — draws the line, and it is worth two minutes to internalize.

Assistance: the government supports your work

A grant exists because the government wants a public purpose advanced and is willing to fund someone else to advance it. Your project, serving their mission. The government's role after award is mostly oversight: reports, audits, compliance.

A cooperative agreement is the same instrument with one difference written into law: the agency expects substantial involvement in carrying out the work. Think of it as a grant where the government is a hands-on partner — helping steer, participating in decisions, sometimes working alongside you. Same application world, same funding announcements, more collaboration after the money lands.

Acquisition: the government buys what it needs

A contract is procurement. The government has a defined need — a system built, a service delivered, research performed to its specification — and is purchasing it. You are a vendor, the document that starts it is a solicitation rather than a NOFO, and performance is governed by a thick body of acquisition regulation. The writing is different too: a grant proposal argues that your vision of the public good deserves support; a contract proposal demonstrates that you can deliver their specification, on time, at the price.

Where each one lives

• Assistance (grants and cooperative agreements) is announced on Grants.gov — the data this site regenerates from daily.
• Acquisition (contracts) is announced in the Contract Opportunities section of SAM.gov — and you can browse the live notices on our free contracts board.

One registration serves both worlds — the SAM.gov entity registration you need for grants is the same one contractors hold — so pursuing assistance now keeps the acquisition door open later.

Which door is yours?

If your organization has a mission and needs support pursuing it, you are shopping for assistance: start with the live grant listings and our guide to how the grant lifecycle works. If your business sells products or services the government might buy, acquisition is your lane — and for technology companies, the SBIR/STTR programs sit usefully between the two worlds: assistance-style R&D funding that is deliberately designed to feed into Phase III procurement. Grants Radar covers both worlds, differently: grants are scored to each member organization, with same-day alerts when a real match posts, while contract opportunities are a separate free board you can browse, updated daily from SAM.gov’s official extract.
