No matter how great your idea is, most people expect that you have it written down. When I was new to inventing, I had no idea what that meant. I searched around but didn't find any universal format for documenting my ideas.
Invention Business Plan Example: The Main Elements : Many different readers and audiences need to see your idea in writing. You will be surprised how many different questions will be asked about your invention. In order to efficiently answer such questions, the document should be designed such that it serves as a detailed yet practical guide and resource to be used by a broad audience. Thus, the elements and content of your plan should be both comprehensive (i.e. can answer most questions about your invention) and adaptable (i.e. can be easily modified) for the purpose of a specific use or audience.
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.
You have to do research and you have to put your thought in to it. You have to follow a certain format that will put everything in perspective. Luckily enough, you can find business plans examples or even templates if you just know where to look.
