So, although a detailed business plan may not be required for an online business, I am going to include it here so you can at least look at and consider each section and determine yourself if it applies to your business.
When submitting my concepts to invention hunts, licensing agents, manufacturers, retailers, engineers, and the patent office, I was asked many different kinds of questions. The questions ranged from "What problem does it solve?" to questions that required extensive research such as "Who is your target market?"
Business plans may target changes in perception and branding by the customer, client, taxpayer, or larger community. When the existing business is to assume a major change or when planning a new venture, a 3 to 5 year business plan is required, since investors will look for their investment return in that timeframe.
Estimated Manufacturing Cost: The ideal situation is to contact manufacturers to get a price quote of how much it would cost to build your invention. But this can be difficult if you don't have exact specifications. The other suggested general rule is to divide your Suggested Retail Price by a factor of 4. For example, if your suggested retail price is $80, then your Estimated Manufacturing Cost is $20.
