Small Business Buddy: "How long should a business plan be? A business plan needs to be whatever length is required to excite the investor, prove that management truly understands the market, and detail the execution strategy. From surveys of investor needs, Growthink has found that 15 to 25 pages of text is the optimum length in which to accomplish this. Any more and the time-constrained investor will be forced to skim certain sections of the plan, even if they are generally interested, which could lead them to miss essential elements. Any less and the investor will think that the business plan has not been fully developed, or he or she will simply not have enough information to make an investment decision."
