## biBerk vs Harper Professional Liability (E&O) Insurance Compared

| Criteria | biBerk Professional Liability / E&O | Harper Professional Liability Insurance |
| --- | --- | --- |

[7](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") [8](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..) |
| Issuing Insurer | Confirm in your quote. | 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.

[6](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [7](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..) |
| Risk Services | Confirm in your quote. | 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. [6](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..) |
