Cooperative Purchasing Contracts: Sourcewell, OMNIA, TIPS

Updated Nov 1, 2026

Learn how cooperative purchasing contracts through Sourcewell, OMNIA Partners, and TIPS work, who can use them, and how small firms can compete.

Cooperative purchasing contracts let participating public agencies buy from contracts competitively solicited and awarded by a cooperative or lead agency. Sourcewell, OMNIA Partners, and TIPS are separate purchasing cooperatives, and each has its own solicitations and contract terms.

As a small business, you can compete to become an awarded vendor, but winning a cooperative contract does not guarantee sales. Buyers also need to be eligible to use the contract under its terms and their applicable purchasing rules.

What cooperative purchasing contracts do

A cooperative purchasing contract is intended to serve more than one public buyer. Instead of each city, school district, or other eligible entity running a separate procurement for the same type of product or service, a buyer may be able to purchase from an existing cooperative contract. Whether it can do so depends on the cooperative's contract, the buyer's eligibility, and applicable state and local rules.

These contracts can cover many kinds of goods and services, but the scope is set by each solicitation and award. A cooperative contract for one category does not automatically cover related work. Read the scope, specifications, pricing, ordering instructions, and contract period before treating a potential buyer as a sales lead.

Cooperative purchasing is one route to state and local public-sector customers. It is different from federal bidding on SAM.gov. For more background on local procurement, see state government contracts and city bids.

How Sourcewell, OMNIA Partners, and TIPS work

Sourcewell, OMNIA Partners, and TIPS each run cooperative purchasing programs. They publish solicitations, receive vendor responses, and award contracts under their own processes. A public buyer may then review an awarded contract and decide whether to use it for a purchase it is allowed to make.

The names are not interchangeable, and a vendor should not assume that one cooperative's award applies to another. Search each organization for current solicitations in your field and read the specific documents. They explain what the buyer is seeking, how to submit, what the evaluation considers, and what obligations apply after an award.

The exact vendor process, contract requirements, and any charges or administrative obligations can vary. Confirm those details in the solicitation and final contract rather than relying on a general description of the cooperative.

How small businesses can compete

A small business can pursue a cooperative contract if it can meet the solicitation's requirements. The opportunity may suit a company that can serve multiple public agencies, maintain the required capacity, and provide clear pricing across the contract's scope. However, an award is not a guarantee that any agency will place an order.

Before preparing a response, check whether the solicitation fits your products, service area, staffing, insurance, licenses, and delivery capacity. Pay attention to required forms, references, minimum qualifications, pricing format, and deadlines. Missing a mandatory item can make a proposal nonresponsive even if your service is a good fit.

If the contract is too large for your company to perform alone, consider whether you can support an awarded vendor as a subcontractor or supplier. Set expectations in writing about the work, pricing, customer contact, and responsibility for performance. Do not represent yourself as an awarded cooperative vendor unless the contract actually names your business.

Evaluate the opportunity before bidding

A cooperative award can take time and resources to pursue. First, identify the buyer types and locations the contract can serve. Then check whether the work matches what your company already does and whether you can deliver at the offered price while covering labor, materials, travel, insurance, overhead, and support.

Look for evidence of demand, but separate a possible sales opportunity from a promise of revenue. Ask public purchasing offices whether they use cooperative contracts for your category and what local steps they require. Check whether the contract permits the specific product or service the buyer needs and whether the buyer must take any additional action before ordering.

For broader market research, review government contracts in Texas and government construction contracts as examples of federal spending data. Those pages do not measure cooperative purchasing sales, so use local procurement records and buyer conversations to assess demand for a cooperative award.

Prepare a clear proposal and pricing

Treat the cooperative solicitation as a formal competition. Build a checklist from its instructions and answer each requirement in the requested order and format. Explain how your company will meet the scope, serve eligible buyers, handle orders, and resolve service issues. Use specific information about your team and capabilities rather than broad claims.

Price carefully. A cooperative contract may be used by buyers in different locations and at different order sizes, so consider the costs and conditions you are agreeing to support. Read all rules about discounts, price adjustments, delivery, warranty, and order size. If a pricing term is unclear, seek clarification through the solicitation's stated process before submitting.

Keep records of your submission, questions and answers, award notice, final contract, and any required reporting. If you are not selected, review any debriefing or feedback available under the cooperative's rules. Use the result to improve future responses.

Help buyers understand how to use the award

After an award, your sales work is not finished. A purchasing office may need to confirm that it is eligible to use the contract and that the requested purchase falls within the awarded scope. Some buyers may also require a quote, purchase order, local approval, or other documentation. Follow the contract and the buyer's process; do not assume that a cooperative award bypasses every local requirement.

Make it easy for a buyer to verify the relevant contract number, awarded items or services, pricing, ordering instructions, and contact details. Respond promptly to quote requests and keep communication clear about what is included and what would require a separate purchase or approval.

If you are new to public procurement, compare cooperative opportunities with local open bids as well. A cooperative contract may provide a path to buyers, while a city or county solicitation may give your business a direct chance to compete for a specific project.

Track orders and perform the contract

Once a buyer places an order, use the purchase order and contract documents to confirm the scope, delivery or service dates, acceptance requirements, and invoice process. Keep records of work completed, materials delivered, approvals, and communications. These records help resolve questions and support accurate invoicing.

Payment terms depend on the contract and the buyer's procedures. Confirm where to send invoices, what supporting documents are required, and who approves them. Do not treat an award announcement as payment or a guaranteed order. Plan cash flow around the work you have actually been authorized to perform.

Stay current on contract notices and any reporting or performance obligations. Tell the buyer and cooperative through the required channels if you encounter a problem that could affect delivery. Strong performance can help build trust, but future purchases still depend on buyer needs and applicable rules.

Frequently asked questions

How do I find government contracts to bid on?

For cooperative opportunities, search Sourcewell, OMNIA Partners, and TIPS for current solicitations in your industry, then read each solicitation's requirements and deadlines. For local open bids, check the purchasing pages for cities, counties, school districts, and state agencies in your service area. Federal opportunities are posted on SAM.gov under Contract Opportunities, and open federal bids can help you explore them.

Can a small business get government contracts?

Yes. A small business can compete for cooperative contracts when it meets the solicitation's requirements, and it can also pursue open state, local, and federal bids. For federal work, check the SBA's size standard for the relevant NAICS code and complete the required registrations before bidding as a prime contractor. A cooperative award or small-business status does not guarantee orders.

How do government contractors get paid?

Payment follows the contract and the buyer's invoicing and approval process. Contractors generally need to submit an accurate invoice and any required proof of delivery, completed work, or acceptance. For a cooperative purchase, confirm the payment terms with the public buyer and follow the contract's instructions.

How do sourcewell contracts work?

Sourcewell contracts are awarded through Sourcewell's procurement process, and eligible participating public entities may be able to buy from an awarded contract. Vendors should review the specific solicitation and contract for scope, pricing, eligibility, and obligations. An award does not ensure that a buyer will place an order.

How are omnia partners contracts and tips contracts different?

OMNIA Partners and TIPS are separate cooperative purchasing programs with their own solicitations, awards, and contract terms. Compare the current documents for each opportunity rather than assuming their vendor requirements or buyer rules are the same. In either case, confirm that a prospective buyer can use the specific contract for the requested purchase.
