A business plan contains several main elements. First, it lays out the mission and the goal of the business. The plan will spell out whether your company is in business to serve a greater good or simply to fulfill an unmet need. Determine whether your business will serve other businesses or supply products to consumers. These are all important elements that should be included.
Next you will need to carefully examine what actually goes into your offering. How many hours does it take to create those one_of_a_kind bracelets? How much does it cost to bake a dozen of your special recipe cookies? How much research goes into "whipping up" a website? Making tangible goods requires space. Do you have room to grow enough squash to actually generate profits? Are these numbers you could sustain beyond the occasional personal or family use of your product or service? The business planning process can be very helpful to "accidental entrepreneurs" as it allows you to decide which ideas are best left as hobbies and which ones could provide some real cash flow.
