An online-only insurer is a company that operates solely through the Internet, without the use of traditional brick-and-mortar stores or agents. This business model allows for lower overhead costs and usually results in more competitive prices for consumers. However, it also means that customers may have limited access to in-person assistance or personalized advice. Despite this potential drawback, online-only insurers have become increasingly popular in the digital age and offer a convenient option for those seeking insurance coverage.
