What changed
FACT (headline-only source): Illinois enacted additional protections for workers on publicly funded projects (Foley & Lardner client alert). HYPOTHESIS: the new law layers reporting/notice/certification duties on top of Illinois' existing prevailing-wage regime, which already compels monthly certified payroll from every contractor and subcontractor on public works. The source text provides the headline and filer class only — the specific new obligations must be pulled from the underlying Public Act before build.
Why now
A fresh statutory change resets compliance behavior: contractors who were muddling through now have a new obligation set and a reason to re-evaluate tooling. Law-firm alerts (Foley) publishing on it means the compliance-services food chain is already monetizing awareness. Being first to wrap the NEW obligations plus the EXISTING monthly filing into one cheap tool captures the re-decision moment.
Converging signals
Three signals meet at one point: (1) a state rule change creating/expanding obligations on publicly funded projects; (2) a defined compelled filer class — every contractor and subcontractor on IL public works; (3) an existing state submission surface — the IDOL certified transcript of payroll portal. Per the system's own heuristic (confidence 0.79), this mandate-portal-filer shape is the founder's highest-fit pattern.
Customer pain
HYPOTHESIS (structural, not sourced from complaints): monthly certified payroll is recurring, deadline-bound, penalty-backed paperwork that small subcontractors do by hand — re-keying payroll data into state-specific formats, tracking apprentice ratios and fringe classifications, and now absorbing a new law they learn about from lawyer alerts. Errors risk withheld payments and debarment from public work, which is existential for a public-works contractor.
Who pays
Illinois public-works contractors and subcontractors (especially 5–50-employee subs without compliance staff), their bookkeepers/outsourced payroll firms, and prevailing-wage consultants who could white-label it. The buyer is compelled: filing is not optional and recurs monthly for the life of every public project.
Solved today
HYPOTHESIS from known market structure: manual entry into the IDOL portal; spreadsheets; national certified-payroll SaaS (LCPtracker, eBacon, Points North) that centers on federal WH-347 and agency-side workflows and is priced/designed for GCs and awarding bodies, not $99/mo subs; or paying a prevailing-wage consultant per project.
Why current solutions are bad
National tools are federal-first and agency-sold — the small IL sub is an afterthought paying enterprise-ish prices for features they don't need. Manual portal entry is re-keyed monthly per project and breaks silently when the law changes (as it just did). Consultants charge a fee that software can undercut — that consulting spend is the wedge, not a moat against us.
Proposed product
A narrow filing bot: connect or upload payroll output (QuickBooks/ADP/Gusto/Foundation/CSV), map employees to classifications once, then every month it generates the exact IDOL-compliant certified transcript of payroll and submits (or produces a one-click upload package) per project, with a deadline calendar, an audit trail, and a plain-English tracker for the new worker-protection obligations (notices, certifications). Charge per contractor/month or per filing. This is the founder's proven ELDT shape: read the mandate → identify the compelled filer → automate the portal submission → charge per transaction.
MVP version
One payroll format (QuickBooks export) → IDOL-formatted certified payroll for one project, plus the deadline tracker and a one-page 'what the new IL law requires of you' checklist. Manual-assisted submission at first (concierge), automated once the portal's bulk-upload/API path is confirmed. 3–5 design-partner subs filing free for one month, then paid.
30-day build
(1) Pull the actual Public Act and IDOL guidance; enumerate the exact new obligations (kills or confirms the 'new burden' half). (2) Register a test IDOL portal account; document the submission format, bulk-upload spec, and whether third-party submission on the contractor's behalf is permitted — the single biggest technical/legal unknown. (3) Build the QuickBooks→IDOL transform. (4) Scrape public bid-award records (founder strength) to build a named list of currently-filing IL contractors.
60-day build
Concierge-file for 5–10 design partners at $49–99/mo; harden the transform against real payroll edge cases (fringes, apprentices, multi-trade weeks); add ADP/Gusto imports; automate submission if the portal path allows; publish an SEO/LLM-quotable 'Illinois certified payroll — new 2026 requirements' guide to catch the compliance-panic search traffic the law alert wave creates.
90-day revenue plan
Convert concierge users to self-serve paid; direct outreach to the bid-award-derived contractor list (every name on it is a compelled filer with a monthly deadline); partner with 2–3 IL bookkeepers/prevailing-wage consultants on a rev-share. Target: 25–50 contractors at ~$79/mo or per-filing equivalent = $2–4k MRR by day 90–120, inside the founder's 180-day window.
Distribution path
Outbound to a self-built list of proven filers from public bid awards and IDOL debarment/contractor records (public-records strength); IL contractor associations and union-signatory subcontractor groups; bookkeepers serving construction; content targeting the new-law search spike. No ad spend, no marketplace, no procurement.
Pricing hypothesis
$79/mo per contractor (unlimited projects) or $15/filing per project per month; consultant white-label tier at $299/mo. Anchored against consultant fees and the labor cost of manual monthly filing; trivially cheaper than enterprise certified-payroll SaaS.
Technical difficulty
Low-moderate: payroll-format parsing, a classification-mapping UI, deterministic output formatting, and portal submission automation. Well inside solo+AI capability; the ELDT app proves the founder has shipped exactly this architecture against a federal portal. Main technical risk is portal automation friction (CAPTCHA, no bulk path) — fallback is generating the upload file for one-click customer submission, which preserves most of the value.
Legal / regulatory risk
Low. Filing agent/preparer roles are normal in payroll compliance. Must verify IDOL permits third-party submission and get customer authorization in the ToS; accuracy liability managed by making the contractor certify before submission (the certification is legally theirs). Founder does not need a license to operate.
Platform dependency
The IDOL portal is a government system — no platform owner can deplatform the tool (per system scoring rules, no platform_policy_risk). Dependency risk is portal redesigns, which are infrequent and hit all competitors equally; being the fastest to re-adapt is itself the service.
Founder fit
Maximal within this system's thesis: state rule change + compelled filer class + government portal + per-filing monetization is a structural clone of his shipped FMCSA ELDT product. Adjacent strengths all fire: public-records mining for the customer list, industrial/construction operational credibility, AI-assisted fast prototyping, demonstrated-value sales.
Breakout potential
Every state with a prevailing-wage law runs a variant of this filing (many with their own portals/forms) — a genuine 50-market replication path where the parser core is reused and only the state format layer changes. Expansion into adjacent compelled filings (apprenticeship ratios, OCIP/insurance certs, workforce-participation reports) on the same customer base.
Final recommendation
PURSUE, gated on a 2-week diligence sprint. The shape is the founder's proven playbook and the demand is structural (compelled monthly filers, recurring deadlines, penalty-backed). But two facts must be verified before building: (1) what the new Illinois Act actually requires (the source is a headline), and (2) whether the IDOL portal permits automated/third-party submission or bulk upload. If both check out, this is a top-decile fit; if the Act is toothless AND the portal is smooth, kill it and reuse the research for the next state.
Next action
Retrieve the full text of the new Illinois Public Act and the IDOL certified transcript of payroll portal documentation; create a test filing account; simultaneously pull 200 IL public-works bid awards to name the first outbound list.
