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.
Explain the fundamentals of the proposed business: What will your product be? Who will your customers be? Who are the owners? What do you think the future holds for your business and your industry?
Include details about all of the following that are applicable to your business in the marketing section of your plan: location and distribution, and promotional strategies, such as packaging, public relations, advertising, and customer service. As a result of exploring these areas, you will naturally need to consider how much you will budget for your marketing efforts. This question is closely connected to your sales forecast, which leads us into the next section of the business plan.
Another key element to the marketing section of your business plan is an outline of your marketing objectives, strategies, and tactics. Writing down the avenues you travel in order to market your business will afford you the opportunity to record what worked and what didn't work. You must be able to measure and calculate the results of your marketing efforts, otherwise, what's the point? If you don't know if something is working for or against you, then it's working against you.
