Counterpart describes a broker-focused platform for small businesses and lists management and professional liability programs. Buyers should compare the named profession, carrier, state, policy wording and any package component on the actual quote. [1](https://yourcounterpart.com/ "Counterpart | Agentic Insurance™") [2](https://yourcounterpart.com/about "About Counterpart") [Counterpart profile](https://spot.insure/insurance-providers/counterpart) ## 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.

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. [12](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [13](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [14](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [15](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance") ## What Are the Key Differences Between Counterpart and Nationwide Professional Liability (E&O) Insurance? ### Service Allegations Described Nationwide describes E&O for claims alleging errors or omissions in professional services. Counterpart’s MPL page describes service-related negligence and financial-loss examples, and its lawyers page identifies claims arising from lawyers’ professional services. Those are related professional-liability subjects, but the examples are not interchangeable policy wording. When comparing proposals for the same service, trace the allegation language into each offered form rather than treating the public descriptions as identical coverage.

Counterpart names distinct occupation programs: miscellaneous professionals, A&E/contractors, allied healthcare, and lawyers. A buyer can use those descriptions to prepare the same services-and-class explanation for both submissions; the class labels provide context for a quote, not a decision that the risk qualifies.

Counterpart: name the relevant occupation program and compare its proposed services wording for the same work.
