I present an overview about the usability of the different business plans. In my study I analyze the following business plan types: The business plan valid in Hungary to be used to apply for European Union financial resource; Recommended business plan necessary for credit application by a chosen financial institution and finally the Business Model Canvas, a creative model appeared in the recent years. The goal of my work is to investigate the different business plans, which can be met by an enterprise during its activities. I recover the literature background of the planning, which is necessary for me to learn the existing research results. Furthermore by the topic choice I put forward the point of view to investigate the practical usability of the theory of the business planning in business life. The best example for this is my own enterprise.
