If you're thinking about starting a business, you likely already have an idea of what you want to sell, or at least the market you want to enter. Do a quick search for existing companies in your chosen industry. Learn what current brand leaders are doing and figure out how you can do it better. If you think your business can deliver something other companies don't (or deliver the same thing, but faster and cheaper), you've got a solid idea and are ready to create a business plan.
Another important component when you are determining how to form an LLC is the creation of an LLC operating agreement. While operating agreements are not required under state law when forming an LLC and do not have to be filed with the state, they are very important documents to create because they help you and any other members of the LLC organize your business, plan for the future, and put all pertinent facts in writing.
