A business plan should be detailed. In listing your products and services for example, you should not really stop by just enumerating them. You also should write down the descriptions and scope of your products and services, touch base on production and identify means on how you can market your "brain - child" to your targeted niche.
Business plans are decision-making tools. The content and format of the business plan is determined by the goals and audience. For example, a business plan for a non-profit might discuss the fit between the business plan and the organization’s mission. Banks are quite concerned about defaults, so a business plan for a bank loan will build a convincing case for the organization’s ability to repay the loan. Venture capitalists are primarily concerned about initial investment, feasibility, and exit valuation. A business plan for a project requiring equity financing will need to explain why current resources, upcoming growth opportunities, and sustainable competitive advantage will lead to a high exit valuation.
It also needs to be written in formal format and style. You have to remember that a business plan is something that you may have to present to your business partners, financial firms and banks. So if you can, refrain from using slang in any part of your plan.
The primary difference between profit and non-profit organizations is that "for-profit" organizations look to maximize wealth versus non-profit organizations, which look to provide a greater good to society. In non-profit organizations, creative tensions may develop in the effort to balance mission with "margin" (or revenue).
