Starting any new business will entail risk, which is also true for opening a franchise. Trends might change, and your sales drop through the floor, a multitude of competitors open up in your area, your business might not make enough money to pay back your financing, or extremely high inflation springs up, meaning your costs rise and your customers can’t buy as much.
For a franchise, risks are the same, you still need customers and need to be able to sell your product or service. However, there are also some added elements with the business model, such as the restrictions on what you can provide or what suppliers you use, which can limit your flexibility. However, overall the franchise model actually has a number of built-in factors which limit potential risk.
