Franchising refers to the method of practicing and using another person's philosophy of business. The "franchisors" authorize the proven methods and trademarks of their businesses to "franchisees" for a fee and a percentage of gross monthly sales. Various tangibles and intangibles such as national or international advertising, training, and other support services are commonly made available by the franchisor. Agreements typically last five to twenty years, with premature cancellations or terminations of most contracts bearing serious consequences for franchisees.
