A great way of adding value to your business plan is by writing it yourself as this will give you the opportunity of confronting all the major issues a business plan deals with. This will provide clarity and a great over view. The thing that scares most of the entrepreneurs out there is the fact that writing a business plan can be a task that would take months. This is not true. If using a professional business plan template, you can easily finish your business plan in less than a day.
Just remember that not hiring a professional writer for putting together your business plan is a great way of adding value to your business plan and, finally, to your company as it is the business plan that will help you raise external capital.
