Cooperative contracts: a guide for public buyers

A cooperative contract is a contract awarded through one competitive solicitation, run by a purchasing cooperative or a lead public agency, that other eligible public agencies can buy from without running their own bid. The buying agency still confirms that its own laws, thresholds and funding rules allow the purchase, and keeps a record of that check.

What is a cooperative contract?

One competitive solicitation, many eligible buyers.

Sourcewell cites the American Bar Association Model Procurement Code for State and Local Governments, which defines cooperative purchasing as "Procurement conducted by, or on behalf of, one or more Public Procurement Units." NIGP, the Institute for Public Procurement, puts it in practical terms: public entities combine their requirements to get volume pricing and cut the time and cost of buying.

How one solicitation serves many agencies

The cooperative or lead agency solicits once, and the result is a cooperative purchasing contract that eligible agencies can use. Sourcewell, for example, sets the scope from member needs, gets approval from its elected board, publishes a public notice, scores proposals against criteria published in the RFP (request for proposals), awards, and posts the contract documents online. Each agency then decides whether a contract meets its own needs and rules, gets a quote from the supplier and orders with the contract number and its Sourcewell account number.

Cooperative contract vs piggyback contract

The terms overlap. Who the solicitation was written for is the real difference.

Many buyers call any purchase from another body's contract a piggyback. NIGP defines piggybacking as a form of intergovernmental cooperative purchasing in which an entity is given the pricing and terms of a contract another entity entered into. Its position paper on cooperative procurement describes several models, including:

Joint solicitation. Agencies combine their requirements and commit in advance to use the resulting contract.
Piggyback. An agency solicits its own requirements and includes an option for others to use the contract as awarded.
Cooperative program. An outside organization works with public entities to set up contracts meant for a broad base of users.

A cooperative program's contract is built for shared use. A piggyback rests on another agency's scope, quantities and terms, and NIGP warns that requirements must stay substantially the same as that contract; expanding the scope may be treated as improper.

Factor	Cooperative contract	Your own RFP	Piggyback
Who solicits	A cooperative or lead agency	Your agency	Another agency, for its own needs
Written for	Shared use	Your exact requirement	The original agency's requirement
Control over specs	Awarded scope only; non-conflicting local terms allowed	Full	Must match the original contract
Staff time	Low	High	Low, plus vetting another agency's contract
Price risk	Quantity and timing are uncertain, so pricing may not be optimal	One large purchase may price lower	Same as a cooperative contract
With federal funds	Show the cooperative's process met 2 CFR 200	Run a 2 CFR 200 process	Show the original process met 2 CFR 200

Benefits and limits

A useful tool, not the answer to every purchase.

What they do well

They save the time and cost of a full solicitation, pool many agencies' volume, and let you review a competitive record instead of recreating it. Sourcewell and NASPO ValuePoint charge buyers nothing to use their contracts.

Where they fall short

NIGP lists the limits. Prices may not be optimal when quantity and timing are unknown. Specs are harder to change. Local, small or disadvantaged suppliers may see fewer chances. Your own large purchase can sometimes be priced lower.

State law can also narrow what you may buy. New York's General Municipal Law § 103(16) covers equipment, materials and supplies and related installation, maintenance and repair services. A construction-law blog reported in May 2026 that a New York court had barred a school district from using a purchasing cooperative's pre-priced contract for the rest of a construction project.

Due diligence before you buy

The cooperative runs the solicitation. Compliance stays with your agency.

Sourcewell says purchasing agencies are responsible for their own due diligence and legal compliance, in consultation with legal counsel. OMNIA Partners says it gives no assurance that a lead agency's process meets an agency's internal requirements. NIGP's checklist, condensed:

Authority. Check your statute, local code, board policy, bid thresholds and local preference rules.
Competitive award. Read the solicitation, notice, evaluation and award. Sourcewell posts contract and solicitation documents on each supplier's Documents tab.
Scope fit. Your purchase must fall within the award's scope and material terms.
Price and terms. Do market research. Check fees, shipping, local delivery, minimum orders and discounts.
Local terms. Add them by purchase order or addendum, without conflicting with the award.
Eligibility. Confirm with the cooperative or lead agency that you can use the contract.
Records. Document why you chose this method, and audit invoices against the contract.

Federally funded purchases: 2 CFR 200.318 to 200.320

Grant money adds a second layer of rules.

Purchases under a federal award must meet 2 CFR part 200. Under 200.317, states and Indian Tribes follow their own procurement policies plus a few listed sections. Cities, counties, school districts and other recipients follow 200.318 through 200.327.

200.318 requires documented procedures consistent with state and local law. Paragraph (e) encourages intergovernmental agreements for shared goods and services and says documented actions of this type meet the competition requirements. Paragraph (i) requires records of the method, contractor selection and price basis.
200.319 requires full and open competition and lists restrictive practices, such as unnecessary experience or bonding requirements and brand-name-only specifications.
200.320 allows informal methods up to the simplified acquisition threshold, requires sealed bids or proposals with public notice above it, and limits noncompetitive buys to listed cases such as a single source or an emergency.

Above that threshold, 200.324 also requires a cost or price analysis, starting with an independent estimate. FEMA asks applicants to use cooperative programs with care: document how the purchase met federal, state and local rules, do that analysis, and include the Appendix II contract clauses. The 2024 revision of 2 CFR 200 applies to awards made on or after October 1, 2024, so check which version governs yours. This is general information, not legal advice.

NASPO ValuePoint

The contracting arm of the National Association of State Procurement Officials. A lead state runs each procurement; entities opt in through a participating addendum.

HGACBuy

Run by the Houston-Galveston Area Council, a Texas political subdivision. Members sign an interlocal contract to use it.

GSA Cooperative Purchasing

Lets eligible state and local governments buy commercial IT, law enforcement and security-related products and services from eligible GSA schedule categories.

State contracts

Some states open statewide contracts to local buyers, as New York's Office of General Services does for certain contracts.

Worked example: utility poles on Sourcewell Contract #060326-BIDR

The same steps apply to generators on Sourcewell Contract #062326-BIDR.

Register with Sourcewell (free for government and education entities) to get an account number.
Read the contract. Sourcewell's utility pole solicitation lists one awarded contract: Sourcewell Contract #060326-BIDR, held by BIDR Technologies, Inc. Its term runs through August 5, 2030. Review its posted documents.
Check your rules, including the 2 CFR 200 steps above if federal money is involved.
Define the need: height (25 to 70 ft), class (1 to 5), material, hardware and field services such as delivery, installation, inspection or a pole loading analysis. See the utility pole contract page and the wood utility poles guide.
Request a written quote through the quote form. Quotes come at contract pricing with a delivery timeline. Delivery to Alaska and Hawaii is quoted separately.
Order and document. Compare the quote with the contract and your market research, record the decision, and issue a purchase order citing Sourcewell Contract #060326-BIDR and your account number.

For generators, Sourcewell's power generation solicitation lists four awarded contracts, including Sourcewell Contract #062326-BIDR. See the power generation contract page and the Sourcewell generator contract guide.

Questions buyers ask

Is a cooperative contract the same as a piggyback contract?

Not exactly, though the terms are used loosely. NIGP treats piggybacking as one form of cooperative purchasing: an agency uses a contract another agency awarded for its own needs. A cooperative program's contract is solicited for shared use from the start. Either way, your purchase must match the awarded scope and terms.

Does it cost anything to use a Sourcewell contract?

Sourcewell says registration is free for government and education entities, there are no fees to use its contracts and there is no obligation to buy. Its reference guide says suppliers fund it through administrative fees on their sales. Businesses, private consumers and for-profit organizations are not eligible.

Can we use a cooperative contract with FEMA or other federal grant funds?

Possibly, but the documentation burden is on you. FEMA asks applicants to show how the purchase met 2 CFR 200 and state, tribal and local rules, to do an independent cost or price analysis, and to include the required federal clauses. Talk to your grant administrator or pass-through entity before you buy.

Can a cooperative contract be used for construction?

It depends on your state law and the contract's scope. Some statutes cover goods and related services but not public works; New York's is one example. Some cooperatives offer construction through job order contracting, which has its own rules. Our job order contracting guide explains how it works.
