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 Liberty Mutual and Simply Business Professional Liability (E&O) Insurance?

### Quote comparison is not binding

Simply Business describes an online flow to answer business questions, compare panel quotes and select a policy; its June 30, 2026 terms say an online quote is not guaranteed and binding requires panel-member approval. Liberty Mutual identifies a Physicians & Surgeons Professional program and says administrators manage its specialty programs. A buyer should wait for Simply Business’s binding confirmation and effective date, while a physician should ask the Liberty Mutual administrator what approval steps apply. [6](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage") [5](https://www.simplybusiness.com/terms-conditions/ "Terms of Service") [3](https://business.libertymutual.com/commercial-solutions/programs/ "Programs")

### Example buyers and named specialty

Simply Business lists consultants, IT professionals, real-estate agents and bookkeepers among examples for which it can help find E&O; those examples do not guarantee eligibility. Liberty Mutual lists a physician-focused professional-liability program marked “PL Only.” A small business should ensure the panel proposal covers its actual services; a medical practice should confirm its specialty and entity directly with the administrator. [6](https://www.simplybusiness.com/business-insurance/professional-liability-insurance/ "Professional Liability Insurance Coverage") [3](https://business.libertymutual.com/commercial-solutions/programs/ "Programs")
