## Research Scope and Use

Use this comparison to evaluate Coalition and Simply Business for Professional Liability (E&O) Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable.

## Summary

Coalition lists duty-to-defend protection and in-house claims handling for MPL and cyber together. Simply Business describes possible E&O legal costs and requires panel approval before binding. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") [9](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage") [8](https://www.simplybusiness.com/terms-conditions/ "Terms of Service")

## What Is Coalition Insurance?

Coalition fits businesses that want cyber insurance bundled with free attack-surface monitoring and alerts, and technology companies that want Tech E&O alongside it. You can't buy it online yourself: you need an appointed broker, and the final price isn't published. [1](https://www.coalitioninc.com/control "Coalition Control") [2](https://www.coalitioninc.com/technology-errors-and-omissions-insurance "Tech E&O Insurance Coverage") [3](https://help.coalitioninc.com/hc/en-us/articles/7608339418395-How-do-I-qualify-for-and-buy-cyber-insurance-from-Coalition "How do I qualify for and buy cyber insurance from Coalition?")

## Simply Business: Online Small-Business Insurance Marketplace

Simply Business describes a digital marketplace and licensed-producer service for small businesses. The policy and selected insurer determine coverage, fees, servicing and claims responsibilities.

## 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. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](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

### Cyber package requirement

Coalition sells miscellaneous professional liability only as an add-on to an Active Cyber Insurance quote, not as a standalone policy. It markets the coverage to businesses providing professional services and includes defense costs, settlements and judgments for alleged errors or misstatements. Simply Business offers an online E&O flow for listed occupations without stating a cyber policy prerequisite. Buyers should compare the total package cost and whether cyber coverage is needed. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability") [9](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage")

### Claims handling and quote approval

Coalition says its in-house team manages both MPL and cyber claims in one place. Simply Business says an online quote is not guaranteed and panel-member approval is required before binding; its reviewed E&O record does not describe a combined claims team. Ask who receives notice for a professional claim and how the quote becomes effective under either route. [6](https://www.coalitioninc.com/legal/disclaimer "U.S. Disclaimers") [8](https://www.simplybusiness.com/terms-conditions/ "Terms of Service")

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

- Ask Coalition whether Active Cyber is required for your MPL quote, what combined limits apply and whether the same claims team handles both lines. [5](https://www.coalitioninc.com/insurance/miscellaneous-professional-liability-insurance "Miscellaneous Professional Liability")
- Ask Simply Business which carrier is proposed, what costs and claims are covered, and what panel approval remains. [8](https://www.simplybusiness.com/terms-conditions/ "Terms of Service")
