Automated Certificate of Insurance Audits for General Liability & Construction and Property & Homeowners – A Compliance Analyst’s Guide

Certificates of insurance (COIs) are supposed to keep the named insured protected when third parties perform work on a site, in a building, or under a contract. In reality, compliance analysts drown in thousands of ACORD forms, endorsements, and contract riders—trying to validate limits, additional insured status, waivers of subrogation, primary and noncontributory wording, and per-project or per-location aggregates before anyone steps on site. The stakes are high: a single lapse or missing endorsement can shift losses back to the owner or general contractor. The challenge has always been scale and complexity.

Nomad Data’s Doc Chat solves this problem head-on. It is a purpose-built, AI-powered suite that can read and reason across entire files of COIs, policy declarations, endorsements, contracts, and vendor onboarding packets. With Doc Chat, compliance analysts can AI audit certificates of insurance automatically, cross-check COIs against contract requirements, and find lapsed COI coverage at scale—turning weeks of manual verification into minutes, with page-level citations and audit trails you can trust.

Why COI Compliance Is So Hard in General Liability & Construction and Property & Homeowners

For General Liability & Construction and Property & Homeowners lines, COI compliance is nuanced, domain-specific, and highly consequential. A compliance analyst must reconcile COIs with contractual risk transfer language across contract agreements, scopes of work, master service agreements (MSAs), and site-specific addenda. In construction, a general contractor may require a subcontractor to carry Commercial General Liability (CGL) with specific ISO endorsements—often CG 20 10 (ongoing operations) and CG 20 37 (completed operations)—with primary and noncontributory wording and a waiver of subrogation (e.g., CG 24 04). For premises and property managers, vendor requirements often include General Liability, Workers Compensation, and Auto Liability, plus umbrella/excess limits, especially for high-hazard trades (e.g., roofing, glass, elevators, plumbing, electrical).

The documents themselves vary widely in structure and reliability:

ACORD 25 (Certificate of Liability Insurance) summarizes CGL, Auto, Umbrella, and Workers Compensation, but it does not grant rights and often lacks endorsement detail.
ACORD 28 (Evidence of Commercial Property Insurance) and ACORD 27 (Evidence of Property Insurance) are used for property exposures (e.g., tenants and vendors providing proof), but endorsements must be checked to confirm requirements like loss payee or mortgagee status.
Endorsements and policy declarations contain the truth about additional insured status, waiver of subrogation, and primary/noncontributory. They are often missing from the initial COI packet.
Contracts may require per-project aggregate (CG 25 03) or per-location aggregate (CG 25 04) endorsements, which rarely appear on the certificate itself.

On the Property & Homeowners side, building owners, HOAs, and property managers have similar complexity when onboarding contractors for routine or emergency maintenance. Handymen, HVAC techs, and roofers must present compliant COIs and proper endorsements before they’re permitted to work on premises. Turnover is high, document quality is inconsistent, and coverage often lapses mid-project. Compliance analysts must prevent uninsured work while avoiding needless delays that frustrate property teams and residents.

How COI Compliance Is Handled Manually Today

Most teams still run COI compliance with email inboxes, shared drives, and spreadsheets. Compliance analysts trawl through attachments to see if the ACORD 25 exists, whether the insured matches the vendor name, and if policy numbers, effective dates, and expiration dates are within the contractual window. Then begins the hunt for endorsements—CG 20 10/CG 20 37, primary and noncontributory language, and waiver of subrogation for both GL and WC (e.g., WC 00 03 13)—followed by follow-ups to brokers for missing items. Renewal calendars are managed in Excel, Outlook, or a GRC tool, and reminders are sent manually.

Typical failure points of the manual approach include:

Surface-level checks: Teams rely on COIs alone, trusting free-text certificate remarks rather than verifying the actual endorsements and dec pages.
Lapsed coverage: Expirations slip through, and vendors keep working with outdated COIs because renewal emails were missed.
Gaps vs. contract: Contract language (e.g., per-project aggregates, specific AI forms, completed operations duration) isn’t systematically checked against policy evidence.
Inconsistent interpretations: One analyst may accept “blanket AI where required by written contract,” another insists on enumerated endorsement forms. Results vary by desk.
Fragmented storage: COIs, policies, endorsements, and contracts live in different folders, naming conventions, or systems of record.
Audit pain: Responding to internal audit, client audit, or regulator queries becomes a file-by-file scramble without page-level citations.
Fraud risk: Edited or outdated forms can slip through; logos and policy numbers might look right but don’t match current declarations.

The result is an overloaded compliance function that spends more time copying dates and limits than mitigating risk. When a premises liability claim occurs on a jobsite or in a common area, the named insured discovers too late that a subcontractor’s coverage was expired or endorsements were never issued—shifting defense and indemnity to the owner or GC.

What a Modern Certificate of Insurance Compliance Tool Must Do

If you are evaluating a certificate of insurance compliance tool, it should exceed basic OCR and keyword search. It must read like a seasoned compliance analyst, reconcile policy and endorsement language with contract terms, and provide defensible, page-cited conclusions. It should also integrate with vendor onboarding and procurement so non-compliant vendors don’t get a purchase order or site pass. That’s exactly the standard Doc Chat was built to meet.

Doc Chat in Action: AI Audit Certificates of Insurance, End-to-End

Doc Chat by Nomad Data automates the COI compliance process for General Liability & Construction and Property & Homeowners with a rigorous, enterprise-grade workflow that scales from dozens to hundreds of thousands of files.

1) Ingestion & Classification at Scale

Doc Chat ingests documents from email inboxes, SFTP, APIs, or vendor portals. It automatically classifies COIs (ACORD 25/27/28), policy declarations, endorsements (e.g., CG 20 10, CG 20 37, CG 24 04), binders, cancellation notices, and contract agreements or vendor onboarding documents. Entire vendor packets can be processed at once—no manual splitting required.

2) Structured Extraction That Mirrors Your Checklist

Beyond standard fields (insured, insurer, NAIC, policy numbers, effective/expiration dates, limits), Doc Chat extracts the specific compliance signals your playbook demands:

Additional insured evidence and form numbers (e.g., CG 20 10 04 13 for ongoing operations; CG 20 37 04 13 for completed operations).
Primary and noncontributory wording (e.g., via CG 20 01 or blanket language in the policy).
Waiver of subrogation on GL, Auto, and WC (e.g., CG 24 04; WC 00 03 13).
Per-project and per-location aggregates (CG 25 03, CG 25 04), designated construction projects, premises schedules.
Umbrella/excess occurrence and aggregate limits; follow-form indicators.
Auto Liability symbols and limits; Hired/Non-Owned auto.
Workers Compensation statutory limits and Employers Liability limits.
Named insured vs. legal entity name matching to vendor master records.
Cancellation/change provisions and notices, with the reminder that COIs don’t confer rights.

Every extraction is backed by page-level citations to the exact line of the endorsement or dec page, so reviewers and auditors can see and verify instantly.

3) Contract-to-Coverage Cross-Check

Doc Chat compares extracted coverage facts against contractual requirements from MSAs, subcontracts, SOWs, or tenant/vendor agreements. If a contract requires completed operations AI for at least two years post-completion, the system checks for CG 20 37 or equivalent blanket forms. If primary and noncontributory wording is required, it confirms the presence of such language in the policy or endorsement—not just the COI remarks box.

4) Compliance Scoring, Gap Reports, and Remediation

Doc Chat outputs pass/fail flags with precise gap explanations and remediation guidance you can share with brokers or vendors. Example: “Fail – Waiver of Subrogation missing for WC. Please provide WC 00 03 13 or employer-specific waiver endorsement. See contract requirement §6.2(b).” The platform can generate vendor-level or project-level compliance dashboards and automatically attach the cited pages for transparency.

5) Monitoring, Renewals, and Alerts

To find lapsed COI coverage at scale, Doc Chat maintains a living calendar of expirations by policy line and vendor. It alerts compliance analysts—and optionally vendors—30/15/7 days before expiration, and can suspend work authorizations in your vendor management or procurement system until compliant renewals are provided and verified. When new documents arrive, the agent re-runs the contract cross-checks; no human rekeying required.

6) Fraud and Anomaly Detection

Doc Chat flags inconsistencies that human reviewers often miss: mismatched policy numbers across COI and dec pages, out-of-date endorsement versions, carrier/NAIC mismatches, or suspicious formatting. Optionally, it can enrich files with third-party data (e.g., carrier identifiers) to strengthen verification, and it keeps a transparent history of every extraction and decision for audit readiness.

7) Real-Time Q&A Across Entire Vendor Files

Analysts can ask natural-language questions and get instant, cited answers across thousands of pages: “List all vendors with completed ops AI,” “Which policies expiring next 30 days lack a waiver of subrogation?” or “Show me the exact primary and noncontributory wording for Acme Roofing’s GL.” This capability transforms reviews from manual scrolling to strategic, question-driven workflows.

Use Cases: From Jobsite Risk Transfer to Property Vendor Onboarding

Construction – General Contractors and Risk Transfer Teams

A GC engages ten subcontractors for a mixed-use development. Contracts require $2M per occurrence / $4M aggregate CGL, per-project aggregates, AI for ongoing and completed ops, primary and noncontributory, waiver of subrogation on GL and WC, Auto Liability with HNOA, and $5M umbrella. Doc Chat ingests every subcontractor’s COIs, endorsements, and dec pages; extracts the required fields; and compares them to the subcontract clauses. Within minutes, the compliance analyst has a pass/fail dashboard with remediation instructions and source citations, preventing non-compliant subs from mobilizing.

Property & Homeowners – Owners, HOAs, and Property Managers

A property manager supports 400 buildings with hundreds of small vendors (HVAC, plumbing, roofing). Doc Chat automates onboarding: vendors upload COIs and endorsements; the agent verifies additional insured and waiver language; and the system syncs status back to the work order platform. When coverage expires, the vendor and property manager are alerted, and the work order is paused until renewal is verified. The result: real protection for the named insured and a smoother vendor experience.

Business Impact: Speed, Cost, Accuracy, and Risk Reduction

Moving from manual to automated COI audits with Doc Chat changes the economics and risk posture of compliance operations.

Cycle time: Reviews that took hours per vendor drop to minutes—even across thousands of documents—thanks to bulk ingestion and instant cross-checking.
Labor savings: Teams reclaim 50–80%+ of analyst hours previously spent on data entry and document hunting. Those hours reallocate to higher-value tasks (contract negotiation, vendor education, risk analytics).
Accuracy and consistency: The AI reads every page with identical rigor and applies your playbook consistently. No fatigue, no missed endorsements.
Real risk reduction: Proactive alerts and verified endorsements reduce the odds that a premises or jobsite claim lands on your policy due to vendor non-compliance.
Scalability for spikes: Surge events or seasonal project ramps no longer require new hires or overtime. Doc Chat scales instantly with volume.
Audit readiness: Page-level citations and immutable audit logs make internal, client, and regulatory audits far simpler.
Vendor experience: Faster onboarding and clearer remediation guidance reduce friction with brokers and vendors.

These outcomes are consistent with what we’ve seen across insurance workflows: when document-heavy processes are automated, accuracy rises while costs and cycle times fall.

Governance, Security, and Auditability

COI compliance touches procurement, legal, operations, and risk. Doc Chat is designed to satisfy each stakeholder:

Compliance and audit: Page-level citations link every decision to the source. Immutable logs record the who/what/when of every action.
IT and security: Nomad Data maintains robust security and privacy controls (including SOC 2 Type 2). Data handling aligns with enterprise standards.
Legal: Doc Chat distinguishes between certificate remarks and enforceable policy language, highlighting where endorsements must be verified.
Operations: Automated reminders and system-enforced holds reduce risk without increasing friction for field teams.

Measuring Program Success

Compliance leaders often begin by benchmarking the current-state program and then tracking improvement across a handful of metrics:

Time-to-compliance: Average days from vendor submission to verified compliance.
Coverage integrity: Percentage of vendors with verified AI/WOS/PNC endorsements (not just COI remarks).
Renewal discipline: Percentage of policies renewed before expiration and verified within 48 hours.
Audit outcomes: Time to respond to audits; number of findings related to documentation or verification gaps.
Loss attribution: Reduction in owner/GC-paid losses due to vendor non-compliance.

As these metrics improve, risk and cost decline while vendor relationships get smoother—fewer back-and-forths, faster approvals, clearer requirements.

Implementation: White-Glove, Fast, and Tailored

Nomad Data’s approach is service-led. You’re not buying a generic tool—you’re gaining a strategic partner. In a 1–2 week implementation, we:

Codify your playbook: Translate your COI and contract requirements into Doc Chat presets (limits, AI forms, WOS, PNC, aggregates, durations).
Validate on real files: Run Doc Chat on your recent vendor packets; compare outcomes to known answers; refine the rules to your exact standards.
Launch and train: Enable drag-and-drop usage on day one; then roll out integrations to vendor management, CLM, and repositories.

This is the same pragmatic approach we’ve used to transform other document-heavy insurance workflows. For perspective on how AI changes the economics of document review, see Reimagining Claims Processing Through AI Transformation.

FAQ: Your Top COI Compliance Questions, Answered

Can AI audit certificates of insurance?

Yes. Doc Chat can run an AI audit of certificates of insurance and their supporting endorsements, declarations, and contracts. It extracts the fields that matter, verifies endorsement language, and cross-checks against the contract to produce pass/fail results with cited evidence.

How do we find lapsed COI coverage at scale?

Doc Chat maintains a live expiration calendar across all vendors and policy lines, sending proactive alerts to vendors and compliance analysts. It can also place holds in procurement or site-access systems for non-compliant or lapsed coverage. This is how teams reliably find lapsed COI coverage at scale.

What fields should we always verify beyond the COI?

COIs alone are insufficient. Verify additional insured status (e.g., CG 20 10 and CG 20 37), waiver of subrogation (CG 24 04 and WC endorsements), primary and noncontributory wording, per-project/per-location aggregates, completed operations duration, and umbrella follow-form status—all on the actual endorsements or policy forms.

Does Doc Chat handle Property & Homeowners vendor workflows?

Yes. Property owners, managers, and HOAs often deal with high vendor turnover and variable document quality. Doc Chat automates onboarding, verifies endorsements, manages renewals, and syncs status to work order systems—preventing uninsured work on premises.

How accurate is Doc Chat on mixed or messy files?

Doc Chat was built for inconsistent, real-world documents. It reads across COIs, dec pages, endorsements, and contracts—even when layouts vary—and returns page-cited answers. For a deeper explanation of why this is different from simple OCR, see Beyond Extraction.

Putting It All Together

Strong contractual risk transfer is only as good as your ability to verify it.
