Coverage Type

Professional Liability Insurance

Also called Errors & Omissions (E&O) Insurance. Protection when your expertise is questioned.

Professional liability insurance protects your business when a client claims your work, advice, or services caused them financial harm. Unlike general liability (which covers physical injuries), professional liability covers the mistakes, oversights, and alleged negligence that can arise from providing professional services.

What Professional Liability Covers

Negligence

Claims that you failed to use reasonable care in providing your professional services, resulting in financial harm to your client. This is the most common type of professional liability claim.

Errors & Mistakes

Claims arising from mistakes in your work—whether it's an accountant's calculation error, a consultant's flawed recommendation, or an architect's design flaw that causes problems.

Omissions

Claims that you failed to do something you should have done, such as missing a deadline, forgetting to file paperwork, or failing to disclose important information.

Failure to Perform

Claims that you didn't deliver the services you promised, didn't complete work on time, or the results didn't meet the standard your client expected.

Misrepresentation

Claims that you gave false or misleading information about your services, qualifications, or the expected outcomes of your work.

Legal Defense Costs

Attorney fees, court costs, expert witnesses, and settlements—even for claims that have no merit. Defense costs can easily exceed $50,000 even for frivolous lawsuits.

Professional Liability vs. General Liability

These two coverages protect against different types of claims. Most service businesses need both.

General Liability
Professional Liability
What It Covers
Physical harm—bodily injury and property damage caused by your business
Financial harm—losses caused by your professional advice, services, or mistakes
Type of Claims
Customer slips in your office, your employee damages client property
Your advice caused a client to lose money, you missed a critical deadline
Example
Client trips over a cord in your office and breaks their arm
Your tax advice results in IRS penalties for your client
Who Needs It
Every business with physical premises or customer interaction
Businesses that provide advice, services, or specialized expertise

Key Point: General liability won't cover claims that your professional advice or services caused financial harm. If a client sues because your work cost them money (not because they were physically injured), you need professional liability insurance.

Who Needs Professional Liability?

Any business that provides advice, services, or specialized expertise. If clients rely on your knowledge and judgment, you're exposed to professional liability claims.

Consultants

Strategic advice that affects client business decisions and outcomes

Accountants & CPAs

Tax preparation, audits, and financial advice with significant consequences

IT Professionals

System implementations, data management, and technology recommendations

Real Estate Agents

Property valuations, disclosure requirements, and transaction guidance

Architects & Engineers

Design errors, specification mistakes, and project oversight

Insurance Agents

Coverage recommendations and policy advice that affects client protection

Financial Advisors

Investment recommendations and retirement planning guidance

Lawyers

Legal advice, court filings, and representation (called malpractice insurance)

Marketing Agencies

Campaign strategy, advertising claims, and ROI promises

Home Inspectors

Property condition assessments and defect identification

Contract Requirements: Many clients—especially larger companies and government agencies—require proof of professional liability insurance before they'll sign a contract. Having adequate E&O coverage opens doors to better opportunities.

Claims-Made vs. Occurrence Policies

Understanding this distinction is critical when buying professional liability insurance:

Claims-Made Policy

Covers claims made during the policy period, regardless of when the incident occurred (as long as it's after your retroactive date). Most professional liability policies are claims-made.

Advantages:

  • Usually lower initial premiums
  • Coverage can be extended with "tail" coverage
  • Common for professional services

Considerations:

  • Must maintain continuous coverage
  • Need "tail" coverage when you retire or change carriers
  • Retroactive date matters significantly

Important: If you cancel a claims-made policy without purchasing tail coverage, you lose protection for past work—even if it was done years ago while you were insured.

Occurrence Policy

Covers incidents that occur during the policy period, regardless of when the claim is filed. Less common for professional liability but preferred when available.

Advantages:

  • Coverage remains even after policy cancellation
  • No need for tail coverage
  • Simpler to understand

Considerations:

  • Higher premiums
  • Less commonly available for professional liability
  • May have longer discovery periods

Important: Occurrence policies provide more peace of mind but come at a higher cost. For many professions, claims-made is the only option available.

Real Claims Examples

See how professional liability responds in common scenarios:

Consultant's Bad Advice

Scenario: A management consultant recommends a restructuring strategy that results in significant revenue loss for the client company.

Coverage: Professional liability covers your legal defense ($75,000) and the settlement ($200,000) when the client sues for the financial damage caused by your recommendation.

Accountant's Error

Scenario: A CPA makes an error on a corporate tax return, resulting in $45,000 in IRS penalties and interest for the client.

Coverage: Professional liability pays for your defense and the client's claim for reimbursement of the penalties, plus any additional damages they claim.

IT Implementation Failure

Scenario: An IT consultant's software implementation causes data loss and three weeks of system downtime for a client business.

Coverage: Professional liability covers the client's claim for lost revenue, data recovery costs, and any contractual penalties they incurred—potentially $500,000 or more.

Real Estate Agent Oversight

Scenario: A real estate agent fails to disclose known foundation issues, and the buyer discovers major structural problems after closing.

Coverage: Professional liability defends you against the lawsuit and covers the settlement for repair costs that can easily exceed $100,000.

Missed Deadline

Scenario: An attorney misses a statute of limitations filing deadline, causing their client to lose the right to pursue a legitimate legal claim.

Coverage: Malpractice insurance covers the attorney's defense and the potential settlement for what the client would have recovered in their case.

What Affects Your Premium?

Professional liability premiums vary significantly based on your risk profile:

Profession Type

Higher-risk professions (medical, legal, financial) pay more than lower-risk fields (marketing, consulting)

Annual Revenue

More revenue typically means larger projects and higher potential damages if something goes wrong

Coverage Limits

$1M/$2M limits are common, but some professions need $5M or more; higher limits cost more

Deductible Amount

Higher deductibles ($5,000-$25,000) lower premiums but increase your out-of-pocket costs

Claims History

Previous claims or lawsuits significantly increase premiums and may limit coverage options

Years in Business

Newer businesses may pay more; established track records can lower rates

Contract Types

Working with large corporations or government contracts often requires higher limits

Retroactive Date

Coverage going back further in time (older retroactive date) costs more but provides better protection

Typical Range: Low-risk consultants might pay $500-$1,500/year for basic coverage. Higher-risk professions like accountants, architects, or IT consultants typically pay $2,000-$10,000+ annually. Lawyers and medical professionals often pay significantly more. Your specific rate depends on your profession, revenue, and coverage needs.
