How Departments Share Buying Authority: A Plain Guide to Public Procurement Authority

Public procurement authority is the legal power a government body has to commit public funds and purchase goods or services. Think of it as official permission to spend taxpayer money on behalf of an agency, department, or district.

In the United States, this authority looks different from the national "Public Procurement Authority" agencies you see in other countries (like Ghana or Kenya). Here, buying authority is spread across federal, state, and local levels, and shared through specific mechanisms we'll explain below.

Understanding where this authority sits is essential for anyone working in SLED sales. The person who can say "yes" to your solution may not be who you expect.

Departments share buying authority in four main ways:

1. Delegation from a central procurement office. A state's central purchasing office grants line agencies the power to buy on their own, up to set dollar thresholds.
2. Cooperative purchasing contracts. Many agencies buy off one competitively-awarded contract, skipping the need to run their own solicitation.
3. Piggybacking on another agency's contract. One agency uses a contract already negotiated by another entity.
4. Interagency acquisition. One agency obtains goods or services through another agency's existing contract.

Each method lets buying authority flow beyond a single office. The result: multiple entry points for vendors, but also more complexity in finding the actual decision-maker.

Delegation is the most common way states share buying authority with individual agencies.

The NASPO Survey of State Procurement Practices defines the delegated procurement authority mechanism this way: "Delegation refers to the power of entities to issue solicitations and make awards without direct approval by the central procurement organization." In other words, an agency can run its own purchasing process up to a certain dollar amount.

These thresholds vary widely. Alabama sets the floor at $1,000, while South Carolina allows agencies to act independently on purchases up to $3 million. The same NASPO survey found that 82% of responding states hold statutory authority to delegate.

Key point: When a purchase exceeds the threshold, it usually routes back to the central procurement office, or triggers a formal solicitation. That's when the government RFP process kicks in.

For vendors, knowing the threshold tells you whether you're dealing with a department buyer or a central procurement officer.

Not all states organize procurement the same way. Understanding the structure helps you find the real authority holder.

Centralized procurement means one office controls most purchasing decisions for the state. Agencies submit requests, but the central office runs the solicitation and awards the contract.

Decentralized procurement spreads authority across departments and agencies. Each unit manages more of its own buying, often for specific categories like IT or professional services.

According to the NASPO Survey of State Procurement Practices, most states are largely centralized for commodity goods but more fragmented for technology and services. Universities and some large agencies are often exempt from central control entirely.

Key point: The "buyer" you need to reach may be a central procurement officer, a department head, or an exempt institution, depending on what you sell and who has authority over that category.

Understanding where authority sits connects directly to the government procurement cycle and when budget windows open.

Cooperative purchasing lets agencies share the work of procurement. One "lead agency" runs a competitive solicitation, awards a contract, and then other agencies buy off that same contract, without repeating the bid process.

This matters because it dramatically shortens the sales cycle. Once your product is on a cooperative contract, agencies across multiple states can purchase without issuing their own RFP.

The NASPO survey confirms the prevalence: "All 43 responding states reported using cooperative contract services, with nearly 98% purchasing from NASPO ValuePoint cooperative contracts."

Major cooperatives include NASPO ValuePoint, Sourcewell, and OMNIA Partners. Sourcewell cooperative contracts combine the buying power of 50,000 government and education entities.

Piggybacking is a related concept: one agency uses another agency's existing contract (even if they weren't part of the original solicitation) when the contract terms allow it.

For vendors selling to state and local government, getting on a cooperative contract can unlock access to thousands of buyers at once. It also changes the score: an agency that can buy off an existing vehicle has a shorter path to purchase than one that has to run its own solicitation, and that belongs in your targeting math rather than in a rep's memory.

Interagency acquisition is how federal agencies share buying authority with each other. One agency obtains goods or services by using another agency's contract.

The Economy Act (31 U.S.C. 1535) provides the default legal authority: it "authorizes agencies to enter into agreements to obtain supplies or services from another agency."

There are two types of interagency acquisitions:

• Direct acquisition. The requesting agency places an order directly against another agency's contract. The servicing agency has minimal involvement beyond providing access.
• Assisted acquisition. The servicing agency actively helps with the acquisition, including requirements development, solicitation, and contract award.

Key point: Which agency runs the award depends on the type. In an assisted acquisition, the servicing agency handles the solicitation and final award. In a direct acquisition, the requesting agency places and manages the order itself.

Interagency acquisition is strictly a federal mechanism. At the state level, cooperative purchasing and piggybacking serve similar purposes but operate under different legal frameworks.

Education procurement shows how buying authority can be distributed across many roles, not just one purchasing office.

The scale is enormous. According to the National Center for Education Statistics, K-12 public school spending reached $767.8 billion for the 2021-22 school year, an increase of nearly 2 percent from the prior year.

At TAM To Target, we work with vendors selling into roughly 130,000 schools and 13,000 districts across the US, and we run the same model across all three of our verticals: K-12, Higher Ed, and State and Local Government. That fragmented market means buying authority is spread across many roles: special education directors, curriculum coordinators, principals, and district-level administrators all play a part.

Key point: In K-12, bottom-up adoption often drives top-down purchasing. A teacher or building-level administrator may champion a solution, but district leadership and budget committees make the final call.

Selling into education means navigating complex decision-making committees, budget cycles, and approval processes. The "decision-maker" is rarely one person. It's a web of stakeholders with shared authority.

Because authority is split and shared, the decision-maker is rarely one person, and rarely where you assume.

Selling well in public-sector markets means identifying which department or agency actually holds budget authority and is in a buying window. This requires more than a contact list. It requires understanding procurement rules, budget calendars, and buying signals as timing levers, and it requires putting all of that into a number a rep can act on.

An account scoring model does that by grading every district, college, and agency in your market on four sub-scores, each 0 to 100 with written reasoning, then combining them into a single Priority Score:

• Fit Score (from Starbridge). How well your product matches the entity. Institution or agency type, FTE count, enrollment, and geography, weighted to your ICP. Refreshed quarterly, since firmographics rarely move.
• Momentum Score (from your CRM). How much momentum you're building in the account. Calls and dispositions, meetings booked, AE feedback, and relationship activity across the whole account. Refreshes continuously.
• Relevance Score (from Starbridge). Whether now is the right time. Open RFPs, contract end dates, board and council votes, budget approvals, and leadership changes, with a link to the source so a rep can open the proof in one click. Refreshes continuously.
• Market Score (from the TAM GTM Brain). What's moving in the market. State and federal budgets, new legislation, procurement rule changes, and funding cycles, routed to the territories each signal actually moves. Refreshed quarterly.

Our recommended starting weights are Fit 35%, Relevance 30%, Momentum 20%, Market 15%, set during onboarding and tuned over time. Procurement rules and public budget calendars aren't just obstacles. They're inputs to Relevance and Market that tell you when an agency can buy.

The score then has to drive the work. All four combine into one Priority Score inside your own HubSpot or Salesforce, not a separate black-box tool. Top accounts pull into a live ranked segment, that segment auto-filters against your DNC list, and accounts route by tier: the highest scores go to AEs with a task and a Slack alert, mid-tier accounts drop into power-dial sessions sorted by score, and the rest get an email-only sequence. Phones stay the primary motion, with email and LinkedIn supporting the sequence.

Key point: Shared authority rewards vendors who take a scored, not sprayed, approach. Reaching the right person at the wrong time wastes effort; reaching the wrong person at any time burns your reputation in relationship-sensitive markets.

This is where public sector GTM engineering comes in, turning knowledge of shared authority into repeatable pipeline.

Shared authority rewards vendors who find the real budget holder and time outreach to their buying window. Generic lists and untargeted outreach don't work in markets where agencies talk to each other and reputation matters.
