Start by writing a description of your business, including what stage of development it is currently in (conception, start_up, first year, mature, exit) and your plans for growth.

Basically, consumers are hunkering down to limit spending, save money, conserve resources, and change the way they've been living. The major influence on the health of an economy is the psychological state of its consumers. When there exists a broad belief that spending beyond necessity is unwise, people will change their habits and as a result, some businesses will have to close their doors. The economy is molting into a new, leaner animal. Rather than react in desperation to avoid doom, firms should interact with the current situation with innovative and forward thinking actions.
Business Description: After the executive summary, you need to write a short description of the business you are going into. You need to give a general description of the industry your business belongs to. You will write about your company's mission statement, goals and objectives, business philosophy, as well as its legal form of ownership (sole proprietor, corporation, LLC, etc.).
