Professional Liability (E&O) Insurance
When clients pay for your expertise, mistakes — even alleged ones — are lawsuits.
What is professional liability insurance?
If clients pay for your judgment, advice, designs, or services, you carry an exposure general liability doesn't touch: financial harm from your professional work. A consultant's recommendation goes wrong, an accountant misses a deadline, an IT firm's deployment corrupts data, an agent overlooks a coverage need — the client sues for the money they lost. Professional liability (errors & omissions) insurance defends those claims and pays settlements and judgments.
Here's the uncomfortable truth: you don't need to make a mistake to face a claim. A significant share of E&O claims are brought by clients who suffered losses and went looking for someone to blame. Defense costs alone — easily $50,000–$150,000 — can sink a small firm even when the claim is groundless. E&O coverage means the carrier's lawyers fight that battle, not your bank account.
What it covers
- Negligence, errors, and omissions in delivering professional services
- Defense costs — attorneys, experts, court fees — even for meritless claims
- Settlements and judgments for client financial losses
- Missed deadlines, project delays, and failure to deliver as promised
- Negligent misrepresentation and breach of professional duty
- Many forms include personal injury (libel/slander) arising from professional services
What it doesn't cover
- Bodily injury and property damage (general liability)
- Intentional fraud or dishonest acts
- Employment disputes (employment practices liability)
- Data breaches (cyber — though combined E&O/cyber forms exist for tech firms)
- Work performed before your retroactive date (see FAQs — this matters enormously)
Coverage components explained
1Claims-Made Coverage Trigger
Most E&O policies are 'claims-made': they cover claims made while the policy is active, for work performed after your retroactive date. This makes continuous, uninterrupted coverage critical — a gap can void coverage for years of past work.
2Retroactive Date
The earliest work date your policy covers. When switching carriers, we always preserve your original retroactive date so your earliest covered work stays covered. Letting it reset is the most expensive invisible mistake in E&O.
3Limits & Defense Costs
Typical limits run $1M/$1M to $2M/$2M. On many forms defense costs erode the limit, so a long lawsuit can consume coverage before any settlement — worth understanding when choosing limits.
4Extended Reporting Period (Tail)
If you retire, sell, or close the business, a 'tail' endorsement extends the window to report claims for past work — essential protection at the end of a professional career.
5Industry-Specific Forms
Real E&O is written for your profession: tech E&O (usually paired with cyber), consultants, architects/engineers, real estate, accountants, healthcare professionals, and insurance agents each get tailored forms. We place coverage with carriers that know your industry.
When you need professional liability coverage
- Clients pay you for advice, analysis, design, or professional services of any kind
- Client contracts require E&O coverage before signing (standard in consulting, tech, and real estate)
- Your state or licensing body mandates it for your profession
- Your work product could cause a client financial loss if it's late, wrong, or incomplete
- You're closing or selling a practice and need tail coverage for past work
Frequently asked questions
I'm careful and good at my job. Do I really need E&O?
Quality reduces risk; it doesn't eliminate claims. Clients sue when projects lose money regardless of true fault, and defending even a baseless claim costs tens of thousands. E&O is less about whether you'll make a mistake and more about who pays the lawyers when a client decides you did.
What's the difference between general liability and professional liability?
GL covers physical harm — bodily injury and property damage. E&O covers financial harm from your professional work — bad advice, errors, missed deadlines. A client tripping in your office is GL; a client losing $200,000 because of your report is E&O. Most service businesses need both.
What does 'claims-made' mean and why should I care?
It means the policy must be in force when the claim is made, not just when the work was done. Practical consequences: never let coverage lapse, always preserve your retroactive date when switching carriers, and buy tail coverage when you close or sell the business. We manage all three for our clients.
How much E&O coverage do I need?
Start from contract requirements (commonly $1M), then consider the size of client engagements — your exposure scales with the financial impact your work can have, not your revenue. A $200k/year consultant advising on $20M decisions needs more than minimum limits. We'll benchmark against your actual engagements.
