A Fort Worth IT contractor runs a server migration for a manufacturing client over a weekend. Monday morning, three years of production records are gone. Nobody was hurt. Nothing was physically damaged — the hardware is fine, sitting right there. The client's loss is entirely financial: reconstruction costs, missed shipments, a compliance headache.
The contractor calls his agent, confident, because he carries a $1 million general liability policy.
That policy will not respond. Not because a carrier is being difficult, but because that loss falls outside what the form was ever written to cover.
GL covers physical harm. That is the whole boundary.
A commercial general liability policy insures bodily injury and property damage. Physical injury to a person, physical injury to tangible property. Someone slips on your wet floor. Your crew puts a ladder through a customer's window. Those are GL claims all day.
What GL does not cover is
economic loss caused by your professional advice, design, or service when nobody was hurt and nothing was physically damaged. Most forms make this explicit with a professional services exclusion, and where there isn't one, the definitions of "bodily injury" and "property damage" do the work anyway.
That is the entire territory professional liability — errors and omissions, E&O — was invented to cover.
The distinction sounds academic until you're the one holding the wrong policy. Ask any of these people:
- A consultant whose staffing recommendation costs the client a season of revenue.
- A bookkeeper who misses a franchise tax deadline and the client eats penalties and interest.
- A real estate agent who omits a known defect in a disclosure.
- An insurance agent who binds the wrong limits and the client is short at claim time.
- An architect or engineer whose drawings force a partial rework on a build near Decatur.
- A marketing firm that runs a campaign using a photo it didn't have rights to.
Not one of those is a bodily injury or property damage claim. Every one of them is a real lawsuit with real defense costs.
The non-obvious part: E&O is almost always claims-made
This is the single most important structural fact about professional liability, and most business owners have never had it explained.
Your general liability policy is almost certainly
occurrence based. The policy in force when the incident happened is the policy that responds — forever. Someone falls in your shop in 2024, sues in 2027, and your 2024 GL policy answers the phone even if you switched carriers twice since.
Most E&O is
claims-made. The policy that responds is the one in force
when the claim is made against you, not when you did the work. Do a project in 2023, get sued in 2026, and it's your 2026 policy that matters. If you don't have one in 2026, nothing responds — even though you were fully insured the entire time you did the work.
That flip has consequences most people learn the hard way.
The retroactive date is the most important number on the policy
Because coverage triggers on the claim date, a claims-made policy needs a second date to define how far back into your past work it reaches. That is the
retroactive date (or prior acts date).
Work performed before the retro date is not covered, period, no matter when the claim comes in. A policy issued today with today's retro date covers you for claims arising from work you do starting today — and gives you nothing for the ten years of work sitting behind you.
When you renew with the same carrier, they normally carry your original retro date forward. That's how continuous coverage builds. Each year of unbroken renewal keeps another year of your history protected.
Break the chain — let the policy lapse for two months between carriers, or take a new policy that resets the retro date to inception — and years of prior work quietly fall out of coverage. Nobody sends a letter about it. It just shows up as a declination on a claim three years later.
When you shop E&O, the retro date is the first thing to check on the new quote, before you look at anything else. A policy that resets your retro date is not the same product. It is a different, much smaller one.
Tail coverage: what happens when you stop
If you switch to an occurrence-form product, retire, sell the business, or simply stop buying E&O, claims-made logic means you have no policy in force when a future claim arrives. Everything you ever did becomes uninsured on the day the policy ends.
The fix is an
extended reporting period, universally called tail coverage. It doesn't cover new work — it extends the window during which a claim arising from prior work can be reported. Tails are typically offered in one, three, five year, or unlimited increments, priced as a percentage of the expiring annual premium, and that percentage climbs steeply with duration.
Two practical notes. First, the option to buy a tail is usually time-limited — often 30 or 60 days after the policy ends. Miss the window and the carrier is not obligated to sell it to you. Second, the tail is bought from the carrier you're leaving, not the one you're joining. If you're winding down a professional practice in Wise County, budget for the tail as a cost of closing, right alongside the final tax filing.
Defense costs usually come out of your limit
On a typical general liability policy, defense is outside the limit. A $1 million GL policy will spend on lawyers and still have the full $1 million available to pay a settlement.
Most E&O is written the other way:
defense inside the limits, sometimes called a wasting or eroding limit. Every dollar your defense attorney bills reduces the money left to settle. Professional liability claims are argument-heavy — expert testimony, standard-of-care disputes, document review — so defense spend is rarely trivial. A $500,000 limit that spends $180,000 on defense has $320,000 left.
That is a real reason to buy a higher limit than the number in your contract, and a real reason to ask how the deductible works too. Some E&O deductibles apply to defense costs from the first dollar. Others apply only to the indemnity payment. Different products, same-looking quote.
Your contracts may already require it
Here's the quiet one. A growing share of Texas client contracts — municipal work, larger commercial clients, general contractor subcontracts, staffing and vendor agreements — now specify a professional liability limit alongside the GL and workers comp requirements. Many owners sign, file the contract, and never read that clause until a certificate request comes back rejected.
If you've signed anything in the last year with an insurance requirements exhibit, go read the exhibit. That's often where the answer to "how much do I need" already lives.
What to do with this
If your business sells advice, design, judgment, or a professional service, the question isn't whether GL is good coverage. It is. The question is whether you've noticed that it was never built for your biggest exposure.
Bring us the full picture — your GL, your
commercial package, your
workers comp if you have employees — and any client contract with an insurance exhibit. We'll tell you plainly whether there's a gap, and if there isn't, we'll tell you that too. If you're a contractor, our guide to
general liability for contractors explains what your GL does cover, which makes the E&O gap much easier to see.
