7 Insurance Mistakes Small Business Owners Make (And How to Avoid Them)

Most small business owners don't realize they have an insurance problem until something goes wrong. By then, it's too late. Here are the 7 most common and most expensive mistakes — and exactly how to fix each one.

Mistake 1: Assuming your homeowner's policy covers your business

If you run a business from home — cleaning, pet sitting, photography, personal training, anything — your homeowner's insurance policy almost certainly excludes it. A client injured at your home studio, equipment stolen while on a job, or a vehicle accident while driving to a client will all likely be denied.

Fix: Get a separate business liability policy before your next client interaction. For most home-based businesses it runs $300–$800/year.

Mistake 2: Buying only GL when you need professional liability too

General liability covers accidents — someone trips, something breaks. Professional liability (E&O) covers claims that your work or advice caused harm. A yoga instructor who adjusts a student's form, a personal trainer whose program leads to a back injury, a photographer who loses wedding photos — these are professional liability claims that GL won't cover.

Fix: Anyone who provides a service or advice needs both. Combined GL + professional liability typically costs $300–$700/year for service businesses.

Mistake 3: Not having a certificate of insurance ready

Venues, GCs, property managers, and commercial clients ask for a Certificate of Insurance (COI) before you can start work. Many small business owners scramble to get one when a deadline is looming — some lose contracts entirely. Getting insurance after you need it is always harder and sometimes impossible.

Fix: Get insured before you start marketing to any clients who might ask. Online carriers can issue a COI the same day.

Mistake 4: Confusing a surety bond with liability insurance

They're different products that protect different parties. Your liability insurance protects you. A surety bond protects your clients and the state if you fail to perform or violate a law. Contractors who say "I have insurance" when a licensing board asks for a bond are in for a surprise.

Fix: Check your state's contractor licensing requirements. Most trades need both a GL policy AND a license bond. They're separate purchases.

Mistake 5: Letting coverage lapse between jobs or seasons

Some business owners cancel insurance during slow seasons to save money. But many policies have prior acts exclusions — if your coverage lapsed when damage occurred, the claim gets denied even if you've since renewed. Worse, some incidents (like mold from a leak) aren't discovered until months after they start.

Fix: Keep coverage continuous. If cost is the issue, ask about lower-limit seasonal options rather than cancelling entirely.

Mistake 6: Not listing clients or venues as additionally insured

When a GC, venue, or property manager requires your COI, they almost always also require themselves to be listed as an "additionally insured" on your policy. This extends some of your coverage to them. Missing this detail can mean a delayed start or lost contract.

Fix: Adding an additional insured is free with most online carriers and takes 2 minutes. Get in the habit of doing it for every new job that requires a COI.

Mistake 7: Buying the cheapest policy without reading what it excludes

A $200/year policy that excludes the most likely claim against your business is worthless. Common exclusions that catch people off guard: pollution exclusions (relevant for pressure washers, pool cleaners), professional services exclusions (relevant for consultants and coaches), and work-at-height exclusions (relevant for window washers and tree trimmers).

Fix: Before binding any policy, ask your carrier specifically: "Does this cover [your most likely claim]?" Get the answer in writing. If it doesn't, find a policy that does.
