A good presentation enhances and highlights information. It adds clarity and aids understanding. Presentation is always important but only to communicate content. Good charts are dynamite when they make numbers easier to read quickly, and they can be essential when numbers are complex.
Good text formatting will make the plan easy to read. Use a legible font and a good mix of section headings and subheadings to make the organization visible. Bullet points are generally easier to read than long paragraphs. Color is good for charts, when it makes numbers easier to understand, but gets in the way when used for text.
Fancy paper, expensive bindings, and excessive presentation are not really needed. Make the paper whatever quality it takes to make the plan easy to read, avoiding some of the more fibrous papers that end up interfering with the printed content. Make the binding a good coil, or some other binding that will hold up to use, but keep it practical so you impress with content, not expense.
