Walk along Green Bay Road through Winnetka, Wilmette, and Glencoe, or through downtown Lake Forest and Highland Park, and you'll pass a dense concentration of professional service firms — financial advisors, attorneys, real estate agents, consultants, accountants, architects. These businesses don't sell products; they sell advice, judgment, and expertise. That's exactly the kind of business a standard insurance policy doesn't fully protect.
The Coverage Gap Hiding in Plain Sight
General liability insurance covers physical risks — a client slipping in your office, property damage, that kind of thing. It does not cover a client claiming that your advice, a missed deadline, or an error in your work cost them money. That's an entirely different category of risk, and it requires an entirely different policy: professional liability insurance, also called errors and omissions (E&O) insurance. If a client alleges negligence, a missed filing, bad financial advice, or a contract dispute over the quality of your work, general liability simply doesn't respond. Without E&O coverage in place, that exposure sits entirely on the business.
What It Actually Costs
The national average for professional liability insurance runs $56-88 per month (roughly $675-1,051 per year) for a small firm with one to four employees carrying $1 million per claim / $1 million aggregate limits — the standard most client contracts require. Higher-risk fields like accounting, financial advising, and architecture tend to run higher, often $3,000-12,000+ per year, reflecting the size of the claims those professions typically face.
It's Often Not Optional
Beyond the risk itself, many corporate clients simply won't sign an engagement letter or contract without proof of E&O coverage — it's become a standard condition of doing business for consultants, advisors, and agencies working with larger clients. If you've never checked whether your contracts require it, that's worth a look before it becomes a deal-breaker mid-negotiation.
A Quick Gut-Check
If your business gives advice, manages money, designs something, or delivers a professional service where a mistake could cost a client real money — and general liability is the only coverage in place — that's a gap worth closing before a claim, not after.

Frequently Asked Questions
Is professional liability insurance the same as general liability? No. General liability covers physical risks like customer injuries and property damage. Professional liability (E&O) covers financial losses arising from professional negligence, errors, or failure to deliver a service as promised. Who typically needs professional liability insurance? Any business that gives advice or provides a professional service — financial advisors, attorneys, real estate agents, consultants, accountants, architects, marketing agencies, and similar fields. Why do some clients require proof of E&O coverage before signing a contract? It protects the client too — if your work causes them financial harm, E&O coverage is what would respond. Many corporate clients now make it a standard contract requirement for exactly that reason.
