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

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. [9](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [10](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [11](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [12](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

### Contract Requirements and Exclusions

Harper says it matches E&O limits to client contract requirements and reads exclusions line by line before purchase. Zurich describes E&O for professional mistakes and failure to deliver services through a modular Pro Plus suite. If a contract sets a minimum limit or a client requires particular wording, give both the contract and service description and ask for written confirmation against the quote. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [8](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance")

### Quote and Availability Details

Harper accepts quote requests online or by phone and says it can issue a certificate the same day when placing coverage that matches a client requirement. Zurich says admitted E&O is available in most states and names technology, manufacturing, and third-party service providers as target classes. Confirm your profession and state with both; Zurich’s record describes broad availability, not universal availability. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [8](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance") [8](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Ask Harper to match the client contract’s required limit and exclusions, then confirm certificate timing; ask Zurich for your state’s form and admitted status.

## Offering Details

| Criteria | Harper Professional Liability Insurance | Zurich Errors & Omissions / Professional Liability |
| --- | --- | --- |
| 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..) | Confirm in your quote. |
| 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..) | Confirm in your quote. |
| 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..) | Zurich names technology, manufacturing and third-party service providers among targeted E&O classes. [8](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance") (Evidence: Company-reported; scope: Zurich U.S. brand; exact underwriting company may vary by policy and state; professional errors and omissions; United States. Company-reported product description; actual coverage, underwriting, limits and state availability are governed by issued policy terms..) |
| 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..) | Zurich says E&O can address professional-service negligence, mistakes or failure to deliver promised services, including defense costs, court fees, settlements and judgments. [8](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance") (Evidence: Company-reported; scope: Zurich U.S. brand; exact underwriting company may vary by policy and state; professional errors and omissions; United States. Company-reported product description; actual coverage, underwriting, limits and state availability are governed by issued policy terms..)<br><br>Zurich’s Pro Plus is a modular suite of coverages in one policy; admitted E&O coverage is available in most states. [8](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance") (Evidence: Company-reported; scope: Zurich U.S. brand; exact underwriting company may vary by policy and state; professional errors and omissions; United States. Company-reported product description; actual coverage, underwriting, limits and state availability are governed by issued policy terms..) |
| 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..) | Confirm in your quote. |
| 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?'..) | Confirm in your quote. |
| Claims Support | Confirm in your quote. | Zurich describes E&O claims specialists and underwriters and says claims are reviewed under policy terms with legal counsel coordination. [8](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance") (Evidence: Company-reported; scope: Zurich U.S. brand; exact underwriting company may vary by policy and state; professional errors and omissions; United States. Company-reported product description; actual coverage, underwriting, limits and state availability are governed by issued policy terms..) |
