The BOP Option

A Business Owner's Policy (BOP) bundles general liability with commercial property coverage into one policy, typically at a 10-20% discount compared to purchasing each separately. BOPs are designed for small businesses and include both GL and property coverage in a single premium. You can often add professional liability (E&O) as an endorsement to a BOP, creating a single comprehensive policy. This is the most cost-effective approach for professional service businesses with a physical office.

FAQ

What is the difference between professional liability and general liability?
Professional liability (E&O) covers financial harm caused by your professional services or advice. General liability (GL) covers bodily injury and property damage. A consultant whose bad advice costs a client $100,000 needs E&O. A contractor who damages a client's property needs GL. Most professional service businesses with client-facing offices need both. The key distinction is financial harm (E&O) vs physical harm (GL).
Can I bundle professional liability and general liability?
Yes. Many insurers offer bundled policies that combine GL and E&O coverage at a 5-15% discount compared to purchasing them separately. A Business Owner's Policy (BOP) bundles GL with commercial property coverage, and you can often add E&O as an endorsement. Bundling simplifies administration (one renewal, one insurer) and eliminates coverage gap disputes between separate policies.
How much does it cost to have both GL and E&O?
For a solo professional service business, expect to pay $1,000-$3,000/yr for both. GL alone costs $400-$1,500/yr for small businesses. E&O alone costs $500-$3,000/yr depending on profession. Bundled or BOP-based pricing typically saves 10-20% compared to separate policies. A CPA with a small office might pay $800/yr for GL and $1,200/yr for E&O, but a bundle could bring the total to $1,700 instead of $2,000.
