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")

## What Are the Key Differences Between CNA and Pie Insurance Professional Liability (E&O) Insurance?

### Provider Role and Eligible Professions

Pie says it helps small businesses obtain E&O from carrier partners rather than underwriting the policy itself, and names architects, contractors, attorneys, engineers, consultants, marketers, counselors, and real-estate agents as professions that often carry it. CNA describes MPL for non-licensed classes such as consultants, staffing firms, and advertising agencies, with a separate Technology E&O product. Ask which carrier and professional class a Pie quote uses, especially for licensed work. [9](https://www.pieinsurance.com/errors-and-omissions-insurance "Errors and Omissions Insurance") [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions")

Pie says E&O can pay legal fees, costs, and damages for claims that advice or services caused harm, including inaccurate advice, misrepresentation, negligence, or violation of good faith; its page distinguishes criminal prosecution. CNA names target classes for MPL and describes a separate Technology E&O route. Ask Pie which carrier and form apply to your profession, and CNA which class or product matches the services.
