A business plan is much more than just words; it is your business. How you present that business to others has significant impact on its ultimate success.
Perhaps in your research
This is your plan. Allow it to speak for you. You may change the order in which specific sections of your plan are presented, with a few exceptions.
What's Set in Stone? What's Flexible?
Always begin your plan with an executive summary and end it with supporting documents.
What appears between these two components is up to you. Add a section, drop a section, or change the section title to better represent your content. Again, your plan is a direct reflection of you and your business idea. Don't be afraid to adapt the content and its order to fit your idea of coherence and fluidity.
