Professional Liability Insurance (Errors & Omissions)

Professional liability — also called errors & omissions (E&O) — covers claims that a mistake, missed deadline, or bad advice in your professional service caused a client financial harm. Unlike general liability, which covers physical injury and property damage, E&O covers purely financial losses: a marketing campaign that used the wrong figures, a missed filing deadline, a software bug that broke a client's workflow. Any business that gives advice, designs something, or manages a client's money, data, or campaigns is exposed to this kind of claim even when the work was done in good faith.

Rates vary by state, revenue, and claims history — always compare multiple quotes.

Not legally mandated for most professions, but frequently required by client contracts before work can begin.

What's covered

  • Legal defense for claims of negligence, error, or omission in professional services
  • Settlements or judgments tied to a covered mistake
  • Claims of missed deadlines or failure to deliver as contracted
  • Copyright/trademark claims tied to creative or marketing work product

What's excluded

  • Bodily injury or property damage (covered by general liability instead)
  • Intentional wrongdoing or fraud
  • Claims arising from services outside your stated professional scope
  • Cyber breaches of client data (a cyber liability policy handles this)

Covers financial harm from a mistake in your advice or work product — not physical injury or property damage.

What drives the price

  • Type of professional service and its typical claim severity
  • Annual revenue and average contract size
  • Claims history and years in business
  • Coverage limit and whether clients contractually require a specific minimum

Real claim example

An agency publishes a paid ad campaign with an incorrect discount code that costs the client six figures in unplanned discounts.

E&O covers the agency's legal defense and a negotiated settlement with the client — roughly $60,000 total.

E&O covers the agency's legal defense and a negotiated settlement with the client — roughly $60,000 total.
Payout from a single real claim — well above the monthly premium
This is exactly why businesses don't skip this coverage.

Professional Liability (E&O) is commonly required for businesses in this situation. At $45–$150/mo, it is one of the most cost-effective ways to protect against a potentially six-figure claim.

FAQs

Is E&O the same as malpractice insurance?

They're the same concept — "malpractice" is just the term used in licensed fields like medicine and law, while "E&O" is the general business term.

Do I need this if I already have general liability?

Yes — GL and E&O cover different things. GL won't pay a claim that your advice or work product caused a purely financial loss.

Does E&O cover work my subcontractors do?

Only if your policy explicitly extends to subcontracted work — confirm this with the carrier if you regularly use subs.
