What can a franchise do for an entrepreneur that he cannot do for himself?
Buying a franchise means that you are buying into a functioning and proven business model. There is a significantly lower rate of failure for franchisees than for entrepreneurs with original business concepts. Almost 80% of new business start-ups fail each year, but with a franchise you will be buying into a proven and successful concept. Additionally, many franchises profit because the items/services they sell already have a name and a reputation behind them.
