A Sales and Marketing Proposal is a written document that lays out an organization’s strategy for boosting sales revenue and growing its customer base. It typically outlines the proposed methods, objectives, goals, and timeline of an organization’s marketing initiative—while also laying out key selling points, contracts, and agreements between buyers and sellers. A successful Sales and Marketing Proposal should clearly define expected outcomes, costs, and risks associated with the strategy in order to ensure buy-in from stakeholders.
