Start from the very beginning understanding that your business plan ought to be specific to your business needs and objectives. Every business ought to have a plan, but not every business needs a full formal plan with carefully crafted summaries and descriptions.
A business plan is a documented set of business goals, objectives, target market information and financial forecasts that you are aiming to achieve over a certain period of time. It is important to prepare a business plan when starting or growing your business and review it regularly to keep it up to date.
Having an understanding with third parties when distributing a plan could be enough protection for some businesses, however others who have innovative business practices or products or services may wish to go further and sign a confidentiality agreement with each person to protect their innovations. It may also be a good idea to include some words in your plan asking the reader not to disclose the details of your plan.
If you don’t have a specific immediate need to show a formal business plan to a banker or investor, then you are probably better off doing just a lean business plan, for your internal use only. To make the best impression on banks and investors, your business plan outline should be presented in the standard business plan format.
