## 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")

## What Are the Key Differences Between Markel Insurance and Simply Business Professional Liability (E&O) Insurance?

### A Stated Product Ceiling Versus Online Quote Shopping

Markel states a $2 million maximum for its miscellaneous E&O product and describes a target of small businesses up to $5 million in revenue. Simply Business focuses on process: answer business questions online, compare quotes, and select a policy. For a buyer, Markel's published maximum offers an initial limit reference, while Simply Business's workflow is the documented route for seeing panel options; its terms say an online quote is not guaranteed and binding requires panel-member approval. [3](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage") [6](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage") [5](https://www.simplybusiness.com/terms-conditions/ "Terms of Service")

### Which Work the Pages Address

Markel calls its product miscellaneous E&O for professional-services claims and identifies targeted small-business industries. Simply Business names consultants, IT professionals, real-estate agents, and bookkeepers as examples of businesses it can help find coverage for. These examples can guide an initial inquiry, but Simply Business says they do not guarantee eligibility; compare the exact services and revenue on the application rather than relying on an industry label. [3](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage") [6](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage")

### Covered Claim Costs

Simply Business lists attorney fees, court costs, settlements, and judgments among costs its E&O policies may cover, subject to policy wording. Markel's product page describes miscellaneous E&O for claims arising from professional services but does not provide the same itemized cost list in its offering record. Ask both to show how defense expenses affect the limit and which contract or service disputes are covered. [6](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage") [3](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

## What Should You Confirm in Markel Insurance and Simply Business Professional Liability (E&O) Insurance Quotes?

- Ask Markel which industries qualify under its targeted appetite and whether a quote can approach its stated $2 million maximum. [3](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

- Ask Simply Business which panel member issues the quote, whether approval is still required, and how attorney fees reduce or sit outside the stated limit. [5](https://www.simplybusiness.com/terms-conditions/ "Terms of Service") [6](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage")
