The length of a business proposal will vary depending on your target audience, list of products, and industry. Some business proposals are only a few pages, while others are more than 50 pages. Regardless, while business proposals should be comprehensive, they should also focus on critical details and concise information. Additionally, building a longer business proposal than necessary may discourage your buyer from reading it. As many business proposals target a potential customer's senior management team, you must understand they have limited time to sit down and read large documents.
