As Subway soon discovered, franchising is an excellent business model if you are thinking of going global. A franchisor does does not need to worry about the laws or taxes of the foreign countries it operates in; it doesn’t need to relocate staff to set up and run subsidiaries abroad; nor does it need to offer language training or cross-cultural courses to staff. The franchisee is responsible for running the business on a day-to-day basis and making sure it complies with the legislation of the country it operates in.
Subway currently operates in more than 86 countries ... so if you have a good idea, such as how to make and sell a submarine sandwich, perhaps you should consider franchising if you want to go global.
