A feasibility study is done before starting a business, when you have the idea for the business but you want to make sure it's feasible, or advisable. Put another way, is it worth your time, effort and money to create this business? Several different professionals may contribute to the study, such as an accountant, entrepreneurs who have opened successful businesses, and Realtors who advise on the worth of the location and pricing, comparing similar businesses in the area.

A business plan details how the business will operate. It assumes your feasibility study has been completed and it was determined the idea is viable. Now you're going to spell out your financial and other objectives, the methods you plan to use to achieve them, and your proposed organizational structure.
