## What Is Nationwide?

Nationwide’s commercial catalogue includes common small-business policies and separate specialty products. A catalogue listing does not establish eligibility or policy terms; confirm the issuing company and coverage for your state and business.

## 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

### Product scope and published limit

Markel describes miscellaneous E&O for professional-services claims in selected small-business industries, with a revenue scope up to $5 million and a product-page maximum of $2 million. Nationwide describes E&O for claims alleging errors or omissions in professional services and says exact eligible classes depend on underwriting; it does not publish a comparable limit in the reviewed claim. A buyer should compare the actual offered limits and verify that the profession is eligible with both providers. [3](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage") [7](https://www.nationwide.com/business/insurance/errors-and-omissions/ "Errors and Omissions Insurance")

### Quote route

Nationwide directs buyers to contact an agent or request a quote, while Markel invites prospective customers or brokers to contact its team. Neither overview establishes bind timing, so provide identical services, revenue and claims details to both before comparing terms. [7](https://www.nationwide.com/business/insurance/errors-and-omissions/ "Errors and Omissions Insurance") [3](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")


Nationwide describes program tailoring through research and financial analysis, whereas Markel publishes a target revenue range and cap for its product. [7](https://www.nationwide.com/business/insurance/errors-and-omissions/ "Errors and Omissions Insurance") [3](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

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

- Ask Nationwide which professional classes, limits and exclusions apply to your service.
- Ask Markel whether your revenue and industry qualify and what limit, trigger and quote timeline it offers.
