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

### Which Businesses Each Targets

Harper writes its policy around the applicant's actual services for consultants, agencies, tech firms and other licensed professionals broadly. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") Vouch instead names a specific set of professional-services segments it markets E&O to: accounting and finance, architecture/engineering/construction, IT consulting, management consulting, and marketing and creative agencies. [4](https://www.vouch.us/professional-services "Insurance for Professional Services Firms")

When comparing Harper and Vouch, use the stated fit categories to rule either provider in or out before spending time on an application.

### A Named Insurer, for One Program

Vouch's program partner Corix discloses that its proprietary products, including its E&O line, are issued by State National Insurance Company or United Specialty Insurance Company:

Corix's disclosures say its proprietary products, including its E&O line, are issued by State National Insurance Company or United Specialty Insurance Company. That names an insurer for Corix-branded E&O products specifically, not for every Vouch professional-liability placement. [6](https://www.corixinsurance.com/legal/disclosures "Legal Disclosures") (Evidence: Company-reported; scope: Corix disclosures page..)

That names a carrier only for Corix-branded placements, not every policy Vouch might place for a professional-services client. [6](https://www.corixinsurance.com/legal/disclosures "Legal Disclosures") Harper's reviewed pages, by contrast, name pricing drivers for this line but no issuing insurer at all. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

### Buying the Policy

Harper describes reading a policy's exclusions line by line before a client buys and issuing a certificate the same day a quote is requested online or by phone. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") Vouch's partner Corix instead offers a downloadable application and directs brokers into an appointment process, while Vouch's own site routes prospective buyers into an online "Get Started" flow rather than an instant certificate. [5](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") [4](https://www.vouch.us/professional-services "Insurance for Professional Services Firms")

## What Should You Confirm in Harper and Vouch Professional Liability (E&O) Insurance Quotes?

- Ask Vouch which carrier would issue your policy if you're placed outside the Corix program named in its disclosures. [6](https://www.corixinsurance.com/legal/disclosures "Legal Disclosures")
- Ask Harper for the issuing insurer and policy limit, since neither is published. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- If your business falls outside Vouch's named professional-services segments, confirm it can still place your E&O coverage. [4](https://www.vouch.us/professional-services "Insurance for Professional Services Firms")
- Ask how long each firm's application-to-certificate timeline actually runs for your business.
