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

Contract Requirements and Exclusion Review

Harper places professional liability through a specialist and says it reads exclusions line by line because policies with the same limit can respond differently. It also says it can match coverage limits to client-contract requirements. Insureon describes E&O for service businesses but its public overview does not detail contract review or policy exclusion analysis. If a customer agreement specifies limits or wording, ask Harper to map those requirements and ask Insureon for the proposed form and a written comparison against the contract. [2] [6]

Work Definition and Defense Costs

Harper describes coverage for errors in work, negligent professional judgment, and legal defense; Insureon describes claims alleging mistakes or unsatisfactory professional work. Those summaries overlap at a high level, but do not establish identical professional-services definitions or exclusions. Have both providers identify coverage for your actual deliverables, client reliance, and any subcontractor work. [2] [6]

Certificate Timing

Harper says buyers can request a quote online or by phone and that it issues a certificate the same day when placing coverage to meet a client contract. Insureon provides an online quote request but its overview does not establish a certificate timeline. Neither source publishes an issuing insurer or standard limit. Ask for binding confirmation and the certificate only after the policy terms meet the contract. [1] [6]

Areas of coverage

Harper

  • role: 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. Professional liability page introduction and 'Why Harper' section.company-reportedSource ↗
  • role: 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. Coverage directory listing plus the E&O page's own description; a naming convention Harper states about itself, not a distinction between two products.company-reportedSource ↗Source ↗
  • eligibility: 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. Professional liability page introduction and FAQ distinguishing it from general liability.company-reportedSource ↗
  • coverage: 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. 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.company-reportedSource ↗Source ↗
  • 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. Professional liability page 'We know this' section; a described review practice, not an independently verified outcome.company-reportedSource ↗
  • application: 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. Professional liability page quote form and FAQ 'My client contract requires E&O. What now?'.company-reportedSource ↗
  • 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. Checked both the professional-liability and errors-and-omissions pages on 2026-09-23; neither names a carrier or a limit figure.not-disclosedSource ↗Source ↗

Insureon
