## 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

### Industry Reach and Named Classes

Heffernan says its small-business group serves sole proprietors through fast-growing companies across construction, food, healthcare, hospitality, nonprofits, real estate, technology, and other industries, and can design a package for unlisted industries. Zurich specifically names technology, manufacturing, and third-party service providers as E&O classes. If your work is outside Zurich’s stated classes, ask both insurers to confirm appetite using your actual service description. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [7](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance")

### Broker Package and Policy Terms

Heffernan shops E&O with insurers and says it researches a custom package after a buyer contacts its small-business team; the reviewed page publishes no limits or retentions. Zurich describes a modular Pro Plus suite and admitted availability in most states, without amounts in the reviewed record. Get the issuing carrier, limit, deductible, and state form in writing from either placement.
