I work in office with a lot of documents routine. In my work I often use template for on https://thegoodocs.com/freebies/business-proposal-templates/ Generally say a business proposal provides a detailed explanation of the goals you have, how you will conduct business and what expenses and profit you can expect; it's a road map for your company that, in theory, anyone should be able to follow if the proposal is written well enough.
