If an online business, you need to go into detail how you will attract customers to your website. General statements like "I will use Face Book ads and email marketing" will contribute almost nothing to helping your cause unless you have detailed statistical analysis of tests you have conducted or of another similar business you have been associated with. If you do not have any data upon which you reference your estimates, it could show lack of proper thought to the remainder of your business plan.
Start by writing a description of your business, including what stage of development it is currently in (conception, start_up, first year, mature, exit) and your plans for growth. Discuss the nature of your business, the main products and services you offer, the market for your products and services, and how and by whom the business is operated.
Right now, growth may sound like an unattainable goal as businesses are grappling just to survive, but hey, "flat is the new up." If a business can keep its doors open and lights on, then it's doing better than many others. But lights and open doors don't make sales, so making changes that attract business is in a sense, striving for growth. It won't be this tough forever, but for now, putting some growth strategies into action may be what keeps your business alive, if not thriving.
Personnel: The success of any company depends on their ability to recruit, train and retain quality employees. The amount of emphasis in your plan for this section will depend on the number and type of employees required.
