A third way to differentiate your proposal is to customize your design and format to suit your client's preferences and expectations. Design and format are the visual elements of your proposal, such as the layout, colors, fonts, images, charts, and graphs. They can have a significant impact on how your client perceives your proposal and how easy it is to read and understand. To customize your design and format, you need to do some research on your client's brand identity, culture, and style. You can then use their logo, colors, and fonts to create a consistent and professional look. You can also use images, charts, and graphs to make your proposal more appealing and clear. You can also consider the format of your proposal, such as whether it is a PDF, a PowerPoint, or a web page, and how it fits your client's needs and preferences.
