While it’s not essential to have a business plan, you may find it easier to get funding if you have one that is well thought out and contains all of the necessary detail about your prospective business.
Any funder worth his or her salt wants to see it right off the bat. Moreover though, a solid business plan is a living document that will continue to guide your efforts as your business grows. A lot of those mistakes (most of them, in fact) are the result of poor planning. Bad location, a marginal niche, having no specific user in mind, raising too much or too little money--all of these issues can be prevented or at least mitigated with good planning.
Executive Summary. The executive summary goes near the beginning of the plan but is written last. It should provide a short, concise and optimistic overview of your business that captures the readers attention and gives them an interest in learning more about it. The executive summary should be no more than 2 pages long, with brief summaries of other sections of the plan.
It is definitely not the most exciting part of starting a business. In fact, if you are like a lot of entrepreneurs, you are probably going to find yourself pulling a few all-nighters to get one done before heading into your first pitch for funding. Because that is the thing--your business plan is a pretty important.
