Finally, a business plan should be error - free. This is important because your business plan defines who you are as a business person. If it turned out sloppy, then that does not speak too highly of you.
Financial Plan- This is the most important part of the business plan where you need to show the three year projection of the projected financial statements, including income statements, pro-forma balance sheets, and monthly cash flow and annual cash flow statements which will help in forecasting your revenues and expenses.
The business goals may be defined both for non-profit or for-profit organizations. For-profit business plans typically focus on financial goals, such as profit or creation of wealth. Non-profit, as well as government agency business plans tend to focus on the "organizational mission" which is the basis for their governmental status or their non-profit, tax-exempt status, respectively—although non-profits may also focus on optimizing revenue.
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.
