A formal business proposal is an official proposal of a business idea written by one party to another, usually as a means for gaining a partnership or financial backing in business. While there is no set format for a written business proposal, an effective and thorough business proposal will include specific information and leave no question unanswered. Writing a thorough business proposal can increase your chance of getting the attention of a party who has the resources to help you launch your business.
Outline the financial elements of the business (where funding will come from), the day-to-day operation of the business and business promotion ideas. Tailor this section to the person or organization you're propositioning so it will be clear what the individual or company's role will be.
