One of the first things a starting entrepreneur should do is compile a business plan. Compiling a business plan forces you to thoroughly think through the planned activities and analyse the business idea in regards to different aspects and thus, helps to avoid mistakes in planning financial decisions.

A starting business does not have a history, i.e. the data, to provide a statistically adequate prediction. Therefore, a business plan and in particular, its financial part, can be taken as a tool for playing through the perspectives.
