When I ask entrepreneurs and small business owners, it is not unusual for not having any marketing plan. I once read that Sir Richard Branson never had any marketing plan when he started the 1st Virgin business many years ago. In fact in one study of entrepreneurship (I couldn't recall the name of the study) was that as much as 50% of entrepreneurs and business owners don't have a business plan and marketing plan when they first started the business.
You will need to develop or define important information about your company. In your business plan, you should have developed a Mission Statement, a Vision Statement, and a Culture Statement. If you did not develop these three items, you must create them immediately before continuing onward. It is vitally important that everyone knows about and buys in to these three company statements with all employee staff so that every person inside the business will communicate these items correctly to all external people outside of the business. You want their belief and confidence as high as the owners or top executives.
