Professional Liability

What Is Professional Liability?

Professional liability insurance is a type of coverage designed to help protect professionals and service-based businesses when a client claims their work, advice, or services caused a financial loss.

Also called Errors & Omissions or E&O, professional liability insurance helps protect your business if a client claims your professional services, advice, or work caused them a financial loss.

This coverage fills an important gap that general liability doesn’t cover, especially for service-based and knowledge-based businesses.

What Does Professional Liability Cover?

Professional liability is designed to cover you when you need it most, even years after the work is done.

Coverage How It Works Why It Matters For E&O

Occurrence

Policy responds based on when the incident/error happened (during the policy period), even if the claim is made later

Many of Insurance Canopy’s policies are occurrence-based E&O, so you generally wouldn’t need tail coverage to protect past work

Claims-made

Policy responds when the claim is made and reported, not just when the work was done

You must have active coverage when the claim comes in

Retroactive date

The earliest date your work can have occurred and still be covered

Work done before this date is generally not covered

Continuous coverage

Keeping your claims-made policy active year after year without gaps

Helps protect work from prior years, as long as the retro date stays the same

Extended reporting period (tail coverage)

Extra time to report claims after the policy ends (for past work)

Helpful if you retire, close your business, or switch policies

General liability and professional liability insurance both protect your business, but they’re designed for very different kinds of risk.

General liability insurance covers physical risks, like bodily injury, property damage, or certain advertising-related claims that can happen during everyday business operations.

Professional liability insurance covers claims tied to your work itself. It helps protect you when a client says your professional services or advice caused them a financial loss. Physical injury or property damage doesn’t have to be involved.

Many service-based businesses carry both types of liability coverage because they cover different, yet equally important risks.

Professional liability insurance is especially important for businesses where clients rely on your expertise, advice, or work product.

You Probably Need Professional Liability If…

  • You give advice, recommendations, or professional opinions that clients rely on
  • You design plans, strategies, programs, or systems that others implement
  • Your work is more intangible (ideas, strategy, training, code, design) than physical
  • Your contracts mention “professional services,” “E&O,” or “professional liability”
  • A mistake in your work could cause a client financial loss (even if no one gets hurt)
  • Clients ask for proof of professional liability or specific coverage limits


Professional liability insurance provides peace of mind, allowing you to do your best work with a little more confidence.
