The business plan is a road map just like Google Map. We use Google Maps to find any location where we want to reach. Same as we use the business plan to see our business direction and destination. The sky is the limit, to take your business to the top level, a business plan is very important. No matters what is your business, planning is required in every business. One of my friends refused to develop a business plan for his book writing service business, but then I exhorted him to plan for his business if he want to take off his business to the sky.
