7.1 Cooperative Due Diligence, Fees and Value
Key Takeaways
Review local authority, original competition, permitted participation, scope, term, and price before using another entity’s contract.
A cooperative administrative fee and any rebate belong in the total-value and public-accounting review.
A cooperative’s reputation does not substitute for the buyer’s independent legal and price due diligence.
"Piggybacking" Legal Prerequisites & Due Diligence
Piggybacking is a specific intergovernmental cooperative purchasing practice where an agency adopts the terms, conditions, and pricing of an existing contract competitively awarded by another public entity, without conducting an independent competitive solicitation. Because piggybacking bypasses the local open bidding process, public buyers must ensure that five due-diligence questions are satisfied before executing a piggyback purchase:
Five cooperative-purchasing due-diligence checks:
1. Statutory Authorization: Local code and state statutes permit contract adoption.
2. Express Cooperative Clause: Master solicitation included clear "piggybacking" language.
3. Scope & Volume Alignment: The purchase matches the original technical and volume scope.
4. Procedural Compliance: The lead agency followed rigorous competitive notice and opening rules.
5. Local Due Diligence: Buyer independently proves the pricing is fair, reasonable, and optimal.
The five due-diligence questions for Piggybacking
- Statutory Authority: The buyer's local charter, municipal code, or state statute must explicitly permit the adoption of contracts awarded by other governmental jurisdictions.
- Express Cooperative / Assignability Clause: The master solicitation and resulting contract must contain an explicit cooperative purchasing clause (often titled an "assignability" or "intergovernmental extension" clause). This clause notifies prospective bidders during the original competition that other public entities may access the contract terms. Check whether the original competition and the applicable cooperative-purchasing law permit the proposed participation. Contract extension and assignment are different concepts; do not assume an assignability clause authorizes piggybacking.
- Scope and Volume Alignment: The proposed piggyback purchase must fall squarely within the scope of work and contemplated volumes of the original master solicitation. For example, if a small rural county bid a contract for 5 utility trucks, a large metropolitan transit agency cannot piggyback onto that contract to purchase 300 transit buses. Expanding scope or grossly exceeding contemplated volumes constitutes an unlawful sole-source award that violates open competition.
- Substantial Procedural Compliance: The lead agency's procurement process must meet or exceed the buyer's home jurisdiction standards. The buyer must review the lead agency's procurement file to confirm that public advertising was adequate, sealed bids/proposals were received properly, evaluation criteria were followed, and conflict of interest rules were respected.
- Independent Price Reasonableness Verification: A public buyer cannot assume that a cooperative contract automatically offers the lowest or most reasonable price. The buyer must verify that the cooperative pricing remains competitive compared to current commercial market rates and direct local bidding, taking into account local freight, quantity discounts, and delivery requirements.
Caution
Piggybacking onto an expired master contract, an uncompeted sole-source contract, or a contract lacking an express cooperative clause is a severe violation of public procurement law. The resulting purchase order can be voided by court order, and the agency may be forced to re-bid the requirement.
Administrative Fees, Vendor Rebates & Transparency
National and regional purchasing cooperatives require operating capital to fund staff, maintain legal contracts, and manage marketing portals. In the cooperative industry, operations are predominantly funded through Cooperative Administrative Fees (CAF):
- Fee Structure: The awarded master contractor pays an administrative fee (as established by the actual cooperative agreement) directly to the cooperative organization based on quarterly sales reports.
- Built-in Cost: Although paid by the contractor, this fee is potentially reflected in the vendor's underlying pricing structure.
- Patronage Dividends / Rebates: Some cooperatives return a portion of the administrative fee to participating public entities in the form of volume rebates or patronage dividends.
Ethical and Financial Stewardship Rules
- No Vendor Inducements: Public buyers must ensure that rebate structures or marketing incentives do not influence contract selection. Solicitation decisions must be made strictly on best value, price reasonableness, and technical suitability, not on administrative revenue returned to the agency.
- Public Accounting Transparency: Any administrative fee rebate or volume dividend received by a public agency must be deposited into the appropriate public general fund or operating account. Under no circumstances may rebates be diverted to discretionary off-book accounts, employee entertainment funds, or private vendor-sponsored travel.
- Price Audits: When evaluating cooperative proposals against direct bidding, the buyer must confirm whether the cooperative price, including the administrative fee, offers best value after comparing price, fees, freight, administrative effort, timing, and suitability against lawful alternatives.
Decision Framework: Piggybacking vs. Independent Solicitation
| Evaluation Factor | Recommend Piggybacking / Cooperative | Recommend Independent Local Solicitation |
|---|---|---|
| Market Availability | Standardized commercial off-the-shelf (COTS) equipment, fleet vehicles, technology hardware, MRO supplies | Custom, highly specialized public works, unique geographic services, or novel local technical solutions |
| Schedule Urgency | Immediate operational need where a 3- to 6-month competitive solicitation cycle would disrupt public services | Sufficient lead time to conduct market research, draft tailored specifications, and execute a local competition |
| Purchasing Volume | Low to moderate local volume where the agency cannot command significant volume manufacturer discounts | High aggregate local volume capable of commanding deep supplier discounts directly from manufacturers |
| Local Specification Needs | Standard industry specifications satisfy 100% of the agency's operational and functional requirements | Agency requires highly customized specifications, unique local delivery terms, or proprietary integration |
| Local Vendor Policy | No statutory local business enterprise preferences or small business subcontracting mandates apply | Jurisdiction has mandatory local preference, Disadvantaged Business Enterprise (DBE), or socio-economic participation goals |
| Administrative Resources | Procurement department has limited staff capacity or lacks specialized subject-matter specification expertise | In-house procurement team has technical expertise and staff capacity to manage a full competitive solicitation |
Assume city law requires express cooperative participation in the original solicitation. A neighboring county’s internal-use contract lacks it. How should the city buyer proceed?
Execute an administrative amendment to the county contract adding the city as a named co-signatory under implied intergovernmental authority.
Process the purchase as an emergency sole-source exception to avoid duplicating public solicitation expenses.
Request that the vendor provide an additional 3% price discount to compensate the city for the absence of cooperative contract language.
Refrain from piggybacking onto the county contract and conduct an independent competitive solicitation, because an existing contract cannot be extended to other public entities without an express cooperative clause in the original solicitation.
A cooperative agreement states that operations are funded by a fee on supplier sales. What does that mean?
Through mandatory annual taxpayer membership dues assessed directly against each participating municipal general fund.
Through direct operational grant subsidies appropriated annually by the federal Government Accountability Office (GAO).
Through statutory administrative fines levied on non-responsive commercial bidders who submit irregular proposals.
Through vendor-paid administrative fees calculated as a percentage of total reported sales volume processed through the master contract.
