The length of a business plan depends on the complexity and scope of your business, but generally, it should be as concise as possible while covering all essential details. For small or startup businesses, a plan can be as short as 10-15 pages, covering key aspects like business objectives, market analysis, marketing strategy, financial projections, and operational plans. Larger businesses or more complex ventures may require a more detailed plan, extending to 20-30 pages or more. The goal is to be comprehensive but not overwhelming?focus on clarity, purpose, and actionable insights to keep the plan engaging and informative.
