## 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")

## What Are the Key Differences Between Liberty Mutual and Pie Insurance Professional Liability (E&O) Insurance?

### Alleged harm from professional services

Pie Insurance describes E&O as covering legal fees, costs and damages for claims that business advice or services caused harm, including inaccurate advice, misrepresentation and negligence. Liberty Mutual’s program directory names Physicians & Surgeons Professional and marks it “PL Only.” One page describes alleged professional-service harm; the other names a clinical program category. For either route, compare the proposed form’s covered-services definition, defense treatment and exclusions. [7](https://www.pieinsurance.com/errors-and-omissions-insurance "Errors and Omissions Insurance") [3](https://business.libertymutual.com/commercial-solutions/programs/ "Programs")

### Audience and policy wording

Pie Insurance frames E&O for professionals whose advice or services may lead to client claims; its product page names examples of occupations that often carry the coverage. Liberty Mutual’s listing identifies physicians and surgeons as a specialty program. A buyer comparing these audiences should request the actual covered-services definition and exclusions from either source of a quote; the listings do not promise that a specific applicant qualifies. [7](https://www.pieinsurance.com/errors-and-omissions-insurance "Errors and Omissions Insurance") [3](https://business.libertymutual.com/commercial-solutions/programs/ "Programs")

## What Should You Confirm in Liberty Mutual and Pie Insurance Professional Liability (E&O) Insurance Quotes?

- Ask Pie Insurance which professional-services definition and exclusions appear in the proposal for your business. [7](https://www.pieinsurance.com/errors-and-omissions-insurance "Errors and Omissions Insurance")
