Harper describes coverage for work errors and defense costs with specialist placement and same-day certificates. Simply Business names common professional services as examples but requires insurer eligibility and approval.

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

Contract requirements and policy review

Harper says it reads policy exclusions line by line because policies with the same limit can respond differently, and it matches limits to the client contracts requiring E&O. Simply Business lists consultants, IT professionals, real-estate agents and bookkeepers as examples, but says eligibility is not guaranteed. If a client requires a certificate or particular limit, ask Harper to compare the wording with the contract and ask Simply Business for the carrier form. [1] [6]

Placement and turnaround

Harper places coverage through a specialist and says it can issue a certificate the same day after a contract-driven placement. Simply Business provides an online application and quote comparison, with panel approval needed before binding. Confirm both the actual effective date and the certificate language before starting contract work. [2] [7]

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

  • Ask Harper to map the contract’s required limit and exclusions to the proposed form and confirm certificate timing. [1]
  • Ask Simply Business which insurer is quoting, whether the limit meets the contract, and what panel approval remains. [7]

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 ↗

Simply Business

Company-published professional-errors-omissions information for U.S. small businesses; availability and actual policy terms depend on the insurer, state and buyer.company-reportedSource ↗
  • eligibility: Simply Business lists consultants, IT professionals, real-estate agents and bookkeepers among the business examples for which it can help find E&O coverage. The examples do not guarantee eligibility.
