## Research Scope and Use

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

Coverdash markets professional liability to small businesses, startups and e-commerce sellers generally. Marsh's professional liability practice instead names specialized industries it serves, including banking, asset managers, venture capital and healthcare and biotechnology, and says it draws on attorneys, economists and actuaries to assess exposure.

## What Is Professional Errors and Omissions (E&O) Insurance?

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. [12](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [13](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [14](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [15](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

### Who Each Company's Page Is Aimed At

Coverdash markets professional liability broadly to small businesses, startups and e-commerce sellers that give advice or deliver work, naming examples including architects, dentists, doctors and real estate agencies. [4](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance") Marsh's professional liability practice instead names a set of specialized industries:

Marsh names specialized industries its professional liability experts serve, including banking and broker/dealers, insurance companies and asset managers, merchant banking and venture capital, accountants, attorneys, architects and engineers, media and entertainment, technology, and healthcare and biotechnology. [10](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") (Evidence: Company-reported; scope: Marsh professional liability page, What We Offer section..)

### How Each Describes What the Policy Covers

Coverdash's page describes coverage through four cards: negligent advice or service, mistakes by the business or an employee, a missed deadline or undelivered work, and legal defense costs even against a baseless claim. [4](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance") [10](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Ask both companies to name the issuing insurer; neither's reviewed page names one. [4](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance") [10](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
- If privacy or computer-security exposure matters to your business, confirm whether Marsh's placed policy includes it and whether Coverdash's policy would need a separate cyber product. [10](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
- Get the limit and retention on your quote from each; Coverdash's page doesn't publish figures, and Marsh's pages don't either. [4](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance") [10](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
- If your business falls outside Marsh's named specialty industries, ask which team or product it would route you to instead. [10](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
