If you are thinking about buying into a franchise system, it is important that you understand exactly how franchising works, what fees are involved, and what is expected of you from the franchise company.
An individual who purchases and runs a franchise is called a "franchisee." The franchisee purchases a franchise from the "franchisor." The franchisee must follow certain rules and guidelines already established by the franchisor, and in most cases the franchisee must pay an ongoing franchise royalty fee, as well as an up-front, one-time franchise fee to the franchisor. Franchising has become one of the most popular ways of doing business in today's marketplace. In most states you cannot drive three blocks without seeing a nationally recognized franchise company.
