You may excuse yourself from writing a business plan by reasoning that you would learn through your experiences and follow your instincts. However, that approach has certain limitations that will hold you back. You will not have a clear idea of where your company fits into the market and how you want the business to progress. Making a business plan does not come with any negatives, and it is always safer to have one ready.
Once you decide to write a business plan, you have to ensure that the document has the correct anatomy to attract investors. Providing a good business overview will convince the readers that you know what you have set out to achieve. Your research will open your eyes to what your target audience wants, based on which you will be able to adjust your plans.
