What Are the Key Differences Between Aon and Coverdash Professional Liability (E&O) Insurance?

Coverage and Policy Design

Aon says it tailors professional-liability structures to the needs of firms in law, accounting and consulting, but does not define covered allegations on its overview. Coverdash says its policy addresses client financial harm from negligent advice or service, employee mistakes, missed deadlines and undelivered work, including legal defense for baseless claims. That gives a buyer concrete scenarios to compare against Aon’s proposed form and the contracts clients require. [1] [3]

Buying Route and Terms

Coverdash distinguishes its general professional-liability policy from Tech E&O and Lawyers Professional Liability, and markets it to small businesses, startups and e-commerce sellers. It offers a digital quote-to-purchase process, while Aon describes advisor-led placement. Coverdash does not publish standard limits or name the issuing insurer; Aon likewise leaves terms and carrier to the placement. Technology and legal firms should check the product split before applying. [1] [3]
