A business proposal is a critical document used to persuade someone to adopt an idea and put it into action. It outlines a proposal to change company procedures, hire staff, obtain funding, solicit contracts, or start a new business. The proposal should define the idea, anticipate objections, and explain how to implement it. Key elements include a title, headings to structure the argument, a summary, appendices with supporting data, and a cover for longer proposals. The tone should convey enthusiasm for the believable idea using facts, logic, and a sense of urgency.
