When should you write the introduction and overview of your business plan?

The introduction and overview of your business plan should be written after you have thoroughly researched and outlined the key components of your business, including your objectives, target market, and competitive landscape. This allows you to create a compelling narrative that encapsulates the essence of your plan and aligns with the detailed information provided in the following sections. Writing these sections last ensures that they accurately reflect the insights and strategies you've developed throughout the planning process.
