Aon tailors E&O structures to professional firms; Kinro assesses services, contracts and retroactive dates to match applicants with a carrier. ## Research Scope and Use Use this comparison to evaluate Aon and Kinro for Professional Liability (E&O) Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote. ## Summary Aon describes tailored professional-liability placement for law, accounting and consulting firms. Kinro brokers E&O and reviews client types, contract terms, prior claims and retroactive dates before approaching carriers. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://kinro.com/products/professional-liability "Professional Liability / E&O") ## What Is Aon? Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account.

Kinro fits U.S. small businesses that want a free review of an existing policy or renewal packet and agent help comparing quotes online. Its pages don't name the insurer behind a given quote, so ask which markets Kinro approached before you switch. [4](https://kinro.com/ "Kinro Business Insurance") [5](https://kinro.com/policy-review "Free Review Of Your Insurance Policy") [6](https://kinro.com/partners/carriers "For Carriers And MGAs") [Kinro profile](https://spot.insure/insurance-providers/kinro) ## What Is Professional Errors and Omissions (E&O) Insurance? Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [8](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [9](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [10](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [11](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance") ## Key Differences in Professional Liability (E&O) Insurance ### Professional Class and Product Scope Aon describes professional liability as a structure tailored to professional-services firms’ needs and names law, accounting and consulting as its practice audience. Kinro says E&O fit depends on the operation and carrier appetite; to quote, it gathers the services performed, client types, revenue, contract terms, prior claims and retroactive dates. That intake gives buyers a clear list of materials to prepare and makes the carrier-matching role explicit. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://kinro.com/products/professional-liability "Professional Liability / E&O") ### Placement Detail and Buyer Decisions Kinro often reviews E&O alongside cyber, general liability and D&O, while Aon’s overview describes professional-services advisory support without naming a specific placement workflow. Kinro’s page does not publish limits, retentions or premiums; Aon also leaves account terms open. Both routes require a quote to establish coverage. Ask how each broker will treat regulated or technical advice and whether the retroactive date preserves prior work. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://kinro.com/products/professional-liability "Professional Liability / E&O") ## What to Confirm in Professional Liability (E&O) Insurance Quotes - Ask Kinro which markets will consider your services and what retroactive date and limits are available. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://kinro.com/products/professional-liability "Professional Liability / E&O") - Ask Aon for the application details, carrier and how it coordinates E&O with cyber and D&O. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://kinro.com/products/professional-liability "Professional Liability / E&O") ## Offering Details | Criteria | Aon Professional Liability / E&O brokerage and risk-advisory offering | Kinro Professional Liability / E&O | | --- | --- | --- | | Role in This Line | Aon presents Professional Liability / E&O as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement..) | Kinro is a broker: it matches a business to a professional liability/E&O carrier rather than underwriting the policy itself, saying the product "can underwrite differently" by operation and that market fit depends on carrier appetite. [7](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page "Routing" and "Market fit" sections..) | | Issuing Insurer | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not found in reviewed sources; scope: Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement..) | Confirm in your quote. | | Who It’s For | Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice. That audience scope does not establish eligibility for every firm or other business. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement..) | Kinro says this coverage commonly fits consultants, agencies, tech services and professional firms, and typically comes up when clients rely on the business's professional advice or deliverables, or a contract requires E&O or professional liability. [7](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page "Common fit" and "Triggers" sections..) | | Coverage Features | Aon describes professional liability as addressing professional-services firms’ liability exposure and says it tailors coverage structures to a firm’s needs. It identifies E&O as a commonly used name for professional-liability insurance; actual policy terms are not stated. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage..) | Kinro describes professional liability/E&O as addressing claims tied to alleged errors, omissions, missed deadlines or service mistakes, and says it covers defense and claim-handling questions that a general liability policy may not address. [7](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page introduction and "Coverage" section; actual terms depend on the carrier and policy placed..) | | Limits and Retentions | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not publicly disclosed; scope: Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed..) | The reviewed page does not publish limits, retentions or premiums for professional liability/E&O; amounts would appear on a quote. [7](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Not found in reviewed sources; scope: Professional Liability / E&O page as read on 2026-09-23..) | | Risk Services | Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions. This is a company-described advisory service, not a claim outcome or policy benefit. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) | Confirm in your quote. | | How to Apply | Confirm in your quote. | To quote professional liability/E&O, Kinro collects the services provided, client types, revenue and contract terms, prior claims and retroactive dates, and whether the business handles regulated, technical, financial or operational advice, and often reviews it together with cyber, general liability and D&O coverage.
