Why Your $1M General Liability Policy Won't Save You From a $5M Mistake

One million dollars sounds like a lot of coverage. But that's the standard per-occurrence limit on a commercial general liability policy (IRMI). It's what most client contracts require. And it is not enough.

Here's the thesis: If you provide any kind of professional service, you need professional liability insurance. General liability covers bodily injury and property damage. It does not cover mistakes in the advice you give, the designs you draw, or the code you write. The Hartford puts it plainly: general liability handles physical risks, professional liability covers the abstract ones (The Hartford). Most small business owners have the first and skip the second. That's a catastrophic gap.

The $1 Million Trap

Think about what a professional liability claim looks like. A client sues you because your advice cost them money. They're not claiming you broke their leg. They're claiming you broke their business. That's a financial loss, not property damage. Your general liability policy won't respond.

Professional liability limits commonly start at $1 million per claim, but higher limits of $2 million to $5 million or more are available for larger projects (IRMI). And here's the kicker: defense costs are usually included within the policy limit (IRMI). That means a $1 million policy can shrink fast when legal fees start eating the limit. The Hartford says attorney fees in E&O claims can run from $3,000 to $150,000, and settlements can reach millions (The Hartford).

Occurrence vs. Claims-Made: The Timing Trap

General liability is usually occurrence-based. Professional liability is usually claims-made-and-reported (IRMI). That difference matters more than most people realize.

Under an occurrence policy, a loss that happens during the policy period is covered even if the claim is filed after the policy expires (The Hartford). Under a claims-made policy, you're only covered if the claim is filed and reported during the policy period—unless you buy an extended reporting period. That's the tail. The Hartford notes it's typically 30 to 60 days, but you can extend it to a year or more for an extra cost (The Hartford).

So if you switch insurers, you need to buy tail coverage for the old policy, or you lose protection for work you did years ago. That's an expense most business owners don't budget for.

The Counter-Argument: "I Have a BOP"

Some readers are thinking, "But I have a Business Owner's Policy. That bundles general liability, property, and business income coverage." True. The Hartford says a BOP combines those three essential coverages (The Hartford). But a BOP is not a substitute for professional liability. It's a bundle of property and casualty coverages, not errors and omissions.

You can add professional liability as a standalone policy or endorsement. The Hartford's average minimum monthly premiums for professional liability include $62 for miscellaneous standalone coverage, $41 for miscellaneous endorsements, $239 for architects and engineers, $38 for healthcare professionals, and $146 for technology-company E&O (The Hartford). Those numbers are per month. Compare that to the average $810 a year for general liability (The Hartford). Professional liability costs more because it covers a risk that can sink you.

What a Real Claim Looks Like

Let's make this concrete. You're a small tech consultancy. You sell a software package to a client. It has a bug that causes a data breach. The client sues you for the cost of notifying customers, credit monitoring, and lost business. That's not a bodily injury. That's a financial loss from your error. Your general liability policy won't touch it. Your cyber policy might cover some third-party costs, but that's separate (The Hartford).

Products liability is included in general liability, but it covers bodily injury and property damage from defective products, not financial losses (The Hartford). If you make a physical product, you're covered for a design defect that injures someone. But if your product fails to perform and the client loses money, that's a professional or contractual claim.

The Market Is Shifting—But Not in Your Favor

You might think you can wait. But the market is getting more complicated. WTW reports that general liability and medical malpractice are behaving counter-cyclically to the overall insurance market, with concerns about social inflation, nuclear jury verdicts, and litigation funding (Insurance Journal). That means rates could rise even while other lines fall. And the Triple-I identifies four drivers of social inflation: third-party litigation funding, plaintiff attorney advertising, increasing contingency fees, and eroding caps on damages (Triple-I). None of that is going away.

The Florida example shows what tort reform can do—the Perryman Group calculated that property-casualty costs there are 14.5% lower because of reforms (Insurance Journal). But most states haven't done that. And even with reforms, the risk remains.

The Bottom Line

Don't rely on your general liability policy to cover professional mistakes. Buy professional liability insurance. If you are a professional, it's not optional. The $1 million limit is a starting point, not a finish line. And if you're in a high-risk field like medicine, the stakes are even higher—45.2% of physicians aged 55 and over have been sued (Insurance Journal).

Quick tip: When you buy professional liability, ask about the retroactive date. Make sure it covers all the work you've done, not just work from today forward. And if you ever switch carriers, budget for tail coverage.

Bottom line: Add professional liability to your portfolio before you need it. The cost is a fraction of the claim.
