Styling a business proposal involves paying attention to design, layout, language, and presentation to create a professional and compelling document.  You can start with a clean and visually appealing cover page with the proposal title, client name, company logo, and date. Next, use consistent formatting, such as clear headings, subheadings, and bullet points, to organize content logically and improve readability. Incorporate visuals, such as charts, graphs, and images, to effectively illustrate key points, data, or concepts.
