The focus of a business plan is to provide a roadmap for the future of the business. It should detail what the company will do, how it will be financed, and what return on investment investors can expect. Business plans are often written by entrepreneurs outlining their own vision for the company. But, it is important to involve other parties in the process as well. This includes investors, stakeholders, and customers. They can offer valuable insights into your product or service that you may not have considered before.
