## 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. [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

### What the Published Offering Defines

Alliance Risk describes E&O for consultants, accountants, architects, agents, technology firms and other professional services, with claims for negligence, breach of contract, misrepresentation and missed deadlines. Berkshire Hathaway Specialty Insurance identifies staffing firms, management consultants, marketing firms and real-estate firms as targets for its Miscellaneous Professional Liability product. If your firm falls into one of those categories, compare the actual professional-services definition and policy exclusions rather than relying on broad audience labels. [4](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") [10](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")

### Buying and Policy Details to Resolve

Alliance Risk says its placement can include review of client contracts, claims-trend analysis and structuring claims-made details such as prior acts, retroactive dates and tail coverage. Berkshire Hathaway Specialty Insurance’s Professional First portfolio describes an in-house claims group experienced in complex, high-value claims. Those are distinct support points: placement-stage contract review versus claims handling. Ask both providers who reviews contract requirements and how prior work, reporting periods and claims assistance are addressed in your proposal.
