It offers comprehensive features such as automated filing, accurate tax reports, economic nexus alerts, and assistance with state registration. It positions itself as an all-in-one solution to eliminate sales tax headaches for US-based businesses. Its strength lies in automating the complexities of US state sales tax, including the ability to ignore marketplace data.
