What is professional liability insurance?
Professional liability insurance (errors and omissions) covers claims that your professional advice or services caused a client financial loss. It matters for consultants, agencies, and service providers. Most product-focused eCommerce sellers do not need it, unless they also sell advice, design, or done-for-you services.
