# Harper vs Vouch Professional Liability (E&O) Insurance

Vouch's partner Corix names two possible insurers for its E&O product; Harper's broader-purpose policy names none.

## Research Scope and Use

Use this comparison to evaluate Harper and Vouch 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. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Vouch places E&O for a named set of professional-services segments through partners such as Corix, which names two possible insurers, while Harper writes a broader-purpose policy without naming a carrier.

## What Is Professional Errors and Omissions (E&O) Insurance?

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. [13](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [14](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [15](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [16](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

### Which Businesses Each Targets

Harper writes its policy around the applicant's actual services for consultants, agencies, tech firms and other licensed professionals broadly. [3](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. [10](https://www.vouch.us/professional-services "Insurance for Professional Services Firms")

### 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. [12](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. [12](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. [3](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. [3](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. [11](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") [10](https://www.vouch.us/professional-services "Insurance for Professional Services Firms")

## What to Confirm in 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. [12](https://www.corixinsurance.com/legal/disclosures "Legal Disclosures")
- Ask Harper for the issuing insurer and policy limit, since neither is published. [3](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. [10](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. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [11](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions")

## Offering Details

| Criteria | Harper Professional Liability Insurance | Vouch Errors & Omissions Insurance |
| --- | --- | --- |
| Role in This Line | Harper places professional liability coverage as a broker, writing the policy around the applicant's actual services rather than underwriting it, and describes a specialist handling the placement. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page introduction and 'Why Harper' section..)<br><br>Harper markets the identical policy under two catalogue entries, "Professional Liability" and "Errors and Omissions"; the E&O page states it is the same policy, just named what a given industry calls it. [4](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") [5](https://www.harperinsure.com/coverages "What We Cover") (Evidence: Company-reported; scope: Coverage directory listing plus the E&O page's own description; a naming convention Harper states about itself, not a distinction between two products..) | Vouch is a broker, not an insurer, for professional errors & omissions coverage. It lists Errors & Omissions among the core coverages it places for professional-services clients, and one of its named program partners, Corix, has a dedicated E&O product. [10](https://www.vouch.us/professional-services "Insurance for Professional Services Firms") [11](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") (Evidence: Company-reported; scope: Vouch's Professional Services page and Corix's cyber/E&O product page..) |
| Issuing Insurer | The reviewed pages name pricing drivers (services performed, revenue, contract size) but do not name the issuing insurer or publish specific limit, retention or premium figures for this line. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [4](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") (Evidence: Not publicly disclosed; scope: Checked both the professional-liability and errors-and-omissions pages on 2026-09-23; neither names a carrier or a limit figure..) | 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. [12](https://www.corixinsurance.com/legal/disclosures "Legal Disclosures") (Evidence: Company-reported; scope: Corix disclosures page..) |
| Who It’s For | Harper targets consultants, agencies, tech firms and licensed professionals whose work product is advice, design or a decision, since general liability doesn't cover a client claiming that work caused a financial loss. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page introduction and FAQ distinguishing it from general liability..) | Vouch markets professional E&O to accounting and finance, architecture/engineering/construction, IT consulting, management consulting, and marketing and creative agency firms. [10](https://www.vouch.us/professional-services "Insurance for Professional Services Firms") (Evidence: Company-reported; scope: Vouch's Professional Services page; not an underwriting appetite guarantee for any specific applicant..) |
| Coverage Features | Harper describes coverage for errors and omissions in the work itself, negligence allegations about professional judgment, and legal defense costs, with limits it says are matched to the client contracts that require the policy. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [4](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") (Evidence: Company-reported; scope: Professional liability page's four coverage tiles; the E&O page adds that claims often surface a year or more after the work was delivered. The issued policy and its exclusions control actual scope..) | Corix describes E&O as protecting a business against claims of negligence, mistakes or inadequate work that cause a client financial loss in the provision of professional services, including legal defense costs and any damages awarded, even when the claim is ultimately groundless. [11](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") (Evidence: Company-reported; scope: Corix's cyber and E&O product page; actual insuring agreements and exclusions are set by the issued policy..) |
| Limits and Retentions | Not described in the reviewed sources. | Neither the Vouch nor Corix pages publish E&O policy limits or retentions. [10](https://www.vouch.us/professional-services "Insurance for Professional Services Firms") [11](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") (Evidence: Not publicly disclosed; scope: Pages checked on 2026-09-23..) |
| Risk Services | Harper says it reads a policy's exclusions line by line before a client buys, because two E&O policies with the same limit can respond very differently to the same claim. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page 'We know this' section; a described review practice, not an independently verified outcome..) | Not described in the reviewed sources. |
| How to Apply | You request a quote online or by phone; if a client contract requires E&O, Harper says it places coverage matching that requirement and issues the certificate the same day. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page quote form and FAQ 'My client contract requires E&O. What now?'..) | Corix's E&O product page offers a downloadable application and directs brokers to start an appointment process; Vouch's own site routes prospective buyers to its online "Get Started" application flow. [11](https://www.corixinsurance.com/products/cyber-and-errors-omissions "Cyber and Errors & Omissions") [10](https://www.vouch.us/professional-services "Insurance for Professional Services Firms") (Evidence: Company-reported; scope: Corix product page and Vouch site navigation..) |
