If your business is all in your head, it’s hard to convince lenders, investors and shareholders that you have a credible company and that you’ll use their funding well. And that’s precisely where a business plan comes in. This highly recognized management tool is basically a written document that describes who you are, what you plan to achieve, how you plan to overcome the risks involved and provide the returns anticipated. Often people think of business plans are limited to starting up new companies or applying for business loans. However, they are also essential to running a business with a clear, well-documented plan.
