Below the Threshold, Beyond Review: Auditing Contract Splitting in Illinois Local Government

Procurement thresholds exist for a reason: at a certain dollar amount, Illinois law and local ordinance require a government to open the purchase to competition. The threshold is not a suggestion. It is the line where sealed bids, published notices, and comparable quotes are meant to replace a phone call and a handshake.

But a threshold only works if the purchase is measured honestly. When a single acquisition is divided into several smaller ones — separate purchase orders, sequential invoices, line items that read like pieces of the same project — the trigger never fires. The government can truthfully say no purchase exceeded the limit. The public is left with no competitive record to review.

This is the split-purchase problem. It is not always illegal. Intent matters, and many small purchases are genuinely separate. But the pattern is detectable, and the records needed to detect it are public. The question for Illinois taxpayers is whether local governments make that pattern easy to see or impossible to find.

Why the threshold matters

Illinois has no single procurement rulebook for local government. The Illinois Procurement Code governs state agencies, but municipalities, townships, road districts, park districts, library districts, fire protection districts, and other units largely set their own purchasing policies. Many local thresholds sit somewhere between $10,000 and $25,000, though the exact figure varies by unit and by ordinance. Below the line, a government may need only informal quotes. Above it, competitive sealed bidding or a formal request for proposals usually applies.

That decentralized structure is not inherently a problem. Local governments differ in size and capacity. The problem is disclosure. A resident who wants to know whether a $40,000 project was split into four $10,000 purchases must first know the threshold, then find the purchase orders, then compare dates and descriptions. Few local websites make that sequence simple.

The legal gray zone

Illinois law does not use the phrase “contract splitting” in every local purchasing statute, and enforcement is uneven. Some policies explicitly prohibit dividing a purchase to avoid competitive review. Others are silent. A government that fragments a purchase may argue that each transaction was independently authorized, that the vendor was the only practical source, or that the purchases were unrelated.

The record is where those arguments meet evidence. Under the Illinois Freedom of Information Act, 5 ILCS 140, citizens can request contracts, purchase orders, invoices, check registers, and board-approved bill lists. Those records may be redacted in limited circumstances, but the financial core — who was paid, how much, and when — is generally public. The Open Meetings Act also requires that board votes on expenditures happen in public session, with minutes that identify the action taken.

What is missing is a central, searchable procurement database for local governments. The state publishes some contract data, but the thousands of units of local government do not report purchases to a single portal. That gap is the transparency blind spot.

The records that expose the pattern

A useful audit starts with the purchasing policy. Request the written policy, the current bid threshold, and any board resolution adopting or amending it. Then request the check register for the past 24 months in electronic format — a spreadsheet, not a scanned PDF if one exists. Ask for vendor payment histories, purchase order logs, procurement card statements, and any list of contracts awarded without competitive bidding.

Specific FOIA language helps. Instead of asking for “all purchasing records,” request “all purchase orders, invoices, and payment records for [vendor name] from January 1, 2024, to the present.” Ask for “the unit’s current purchasing policy and bid threshold” and “all bid tabulations or quote summaries for purchases between $5,000 and the bid threshold” for a defined period. Narrow requests are easier to fulfill and harder to deflect.

Five signals of fragmentation

First, clusters just below the line. A vendor paid $9,850 repeatedly, when the threshold is $10,000, deserves a closer look. Second, multiple purchase orders to the same vendor within a short window — 30, 60, or 90 days. Third, descriptions that read like parts of one project: “phase one,” “additional materials,” “installation support,” “remaining balance.” Fourth, annual spending with a vendor far above the threshold but no competitive bid on file. Fifth, repeated use of “emergency” or “professional services” labels for purchases that do not obviously fit either category.

A sixth signal is quieter: the same small group of vendors supplying quotes over and over. Competitive quotes are supposed to be independent. When the same three firms appear in rotation, the competition may be ceremonial.

A reader’s audit in one afternoon

Start with the policy and the threshold. Pull the check register into a spreadsheet. Sort by vendor and total the payments over 12 and 24 months. Flag any vendor whose annual total exceeds the threshold but whose individual payments do not. Request the purchase orders for those vendors. Compare dates, descriptions, and authorization signatures. Then request the bid tabulations or quote summaries. If the government cannot produce them, ask why.

This is not a gotcha exercise. It is a records review. Some flags will resolve innocently: a vendor may have been under a state master contract, or the purchases may genuinely be separate. The point is to make the government explain the sequence on the record.

Grading the paper trail

Illinois Open Gov applied a simple rubric to the public purchasing records of a sample of local governments: Is the purchasing policy posted online? Is the bid threshold stated clearly? Is the check register line-item and searchable? Are purchase orders disclosed? Are bid tabulations published? Are vendor totals available without a FOIA request?

The structural grades were uneven. Policy availability often earned a C: many units post a policy, but few state the threshold in plain language on the same page. Check register detail ranged from B to D, depending on whether the file was a spreadsheet or a scanned image. Purchase order disclosure was consistently weak, often a D. Bid tabulations were the weakest category, frequently unavailable without a formal request.

Those grades measure disclosure, not intent. A government can have a clean procurement process and a poor public record. But a poor public record makes a clean process impossible to verify.

What good looks like

Good purchasing transparency is not complicated. Publish the threshold. Prohibit splitting in writing. Track cumulative spending by vendor and by project, not just by purchase order. Require board approval for any purchase over a set amount, regardless of how it is divided. Publish bid tabulations and quote summaries. Post the check register in a searchable format every month.

None of that requires new technology. It requires the decision to treat the threshold as a public accountability line rather than an internal convenience.

The bottom line

Contract splitting is not always unlawful, and a low-dollar purchase is not automatically a scandal. But when the records make fragmentation hard to detect, the public cannot tell the difference between prudent management and avoided competition. The fix starts with a request: ask for the policy, the threshold, and the check register. Then ask the government to show its work.
