## 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. [7](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [8](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [9](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [10](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

### Zurich names target business classes
Zurich identifies technology, manufacturing and third-party service providers as E&O target classes. Simply Business gives consultants, IT professionals, real-estate agents and bookkeepers as examples, with eligibility depending on the offer. A manufacturer or service provider should check that the proposed marketplace insurer accepts its operations, while Zurich buyers should confirm class fit in underwriting. [6](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance") [3](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage")

### Zurich describes a modular policy structure
Zurich says Pro Plus is a modular suite of coverages in one policy and admitted E&O is available in most states. Simply Business describes online quote comparison but does not establish whether a specific E&O offer is standalone or part of a package. Ask for the complete schedule of coverage and identify any lines bundled together. [6](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance") [3](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage")

### Claims resources are specified at Zurich
Zurich describes E&O claims specialists and underwriters who review claims under policy terms and coordinate with legal counsel. Simply Business’s published overview identifies possible legal expenses but does not describe claims handling. Ask its proposed insurer who receives notice and coordinates counsel for an E&O claim. [6](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance") [3](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage")
