A creative agency proposal is a document that outlines the services and solutions offered by an advertising or creative agency for a client. It presents the goals, plans, strategies, tactics and budgets of the agency and how they will help the client meet their objectives. The proposal should be written in an engaging tone with clear visuals and the explanation of how and why the agency’s services are effective for the problem specified by the client. This document should also explain why the specific agency is best suited to provide the services requested.
