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.
