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. 1,2
What Is Coverdash Insurance?
Coverdash suits small businesses that want online shopping or an embedded partner purchase with one account for policies and billing; firms needing specialized complex-risk advice should compare broker-led programs. 4,5,6

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. 9,10,11,12
Key Differences in Professional Liability (E&O) Insurance
Coverage and Policy Design
Aon says it tailors professional-liability structures to the needs of firms in law, accounting and consulting, but does not define covered allegations on its overview. Coverdash says its policy addresses client financial harm from negligent advice or service, employee mistakes, missed deadlines and undelivered work, including legal defense for baseless claims. That gives a buyer concrete scenarios to compare against Aon’s proposed form and the contracts clients require. 3 7
Buying Route and Terms
Coverdash distinguishes its general professional-liability policy from Tech E&O and Lawyers Professional Liability, and markets it to small businesses, startups and e-commerce sellers. It offers a digital quote-to-purchase process, while Aon describes advisor-led placement. Coverdash does not publish standard limits or name the issuing insurer; Aon likewise leaves terms and carrier to the placement. Technology and legal firms should check the product split before applying. 3 7

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.[4][6][7]

Coverdash offers convenient quote comparison, but public customer feedback is sparse. A BBB unanswered-complaint record makes responsiveness worth checking before purchase.[1][4][6]

Aon vs Coverdash: Professional Liability (E&O) Insurance: documented features by provider
| Criteria | Aon Professional Liability / E&O brokerage and risk-advisory offering | Coverdash Professional Liability (E&O) Insurance |
|---|---|---|
| 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. 3Company-reported. Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement. | Coverdash arranges professional liability (errors and omissions) coverage as a broker rather than an insurer, placing coverage with a carrier under its standard brokerage terms. 6,7Company-reported. General brokerage terms applied to the professional liability page; not specific to any one carrier or state. |
| 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. 3Not found in reviewed sources. 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. | The professional liability page does not name the insurer that issues the policy. 7Not publicly disclosed. Reviewed professional liability page as of 2026-09-23; the page describes coverage without naming a specific carrier. |
| 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. 3Company-reported. Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement. | Coverdash markets professional liability to any small business, startup or e-commerce seller that gives advice, provides a service or delivers work for clients, citing examples including architects, dentists, doctors and real estate agencies. 7Company-reported. Product-page eligibility description; actual acceptance depends on underwriting and profession-specific appetite. |
| 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. 3Company-reported. 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. | Coverdash describes professional liability as covering claims that a client's financial harm came from the business's negligent advice or service, mistakes made by the business or an employee, or a missed deadline or undelivered work, and pays legal defense costs even for a baseless claim. 7Company-reported. Product-page coverage cards; the issued policy and declarations control actual wording, limits, exclusions and whether the policy is claims-made. Coverdash's coverage hub lists this general professional liability product separately from Tech E&O (for technology companies) and Lawyers Professional Liability, so a technology or legal business would typically be pointed to the more specific product instead. 8Company-reported. Coverage hub category structure; does not establish which product a given underwriter would actually issue. |
| 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. 3Not publicly disclosed. Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed. | The professional liability page does not publish specific limit, retention or deductible amounts. 7Not publicly disclosed. Reviewed professional liability page as of 2026-09-23; figures are quote-specific and not shown on the public product page. |
| 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. 3Company-reported. 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. | Coverdash describes a fully digital quote-to-purchase process for professional liability, with the option to add coverages such as general liability or cyber alongside it. 7Company-reported. Product-page company information and cross-sell section. |
