A business plan contains several main elements. First, it lays out the mission and the goal of the business. The plan will spell out whether your company is in business to serve a greater good or simply to fulfill an unmet need. Determine whether your business will serve other businesses or supply products to consumers. These are all important elements that should be included.
As a matter of fact, did you know that the Small Business Administration says that 50% of small business owners will fail sometime during their first 5 years?
