A business plan allows a company to create a written projection of how it will succeed. Because the plan is written out, others involved in the business can understand where the company is going and what is needed to get it there. Additionally, the plan is used for attracting investors, since all investors will want to review a detailed analysis of how the company will become profitable.
The business plan includes several important components — market size, marketing plan, costs, budget, customer profile, competitors, and timeframe to profitability. From the business plan, additional analysis can be performed, making the plan more accurate. Without a business plan, founders will have a difficult time describing their vision to others in detail, attracting investor money, or even getting a loan.
