Your proposal should have a logical and coherent structure that guides your client through your offer. To begin, a brief executive summary should provide an overview of your proposal, value proposition, and main recommendations. After that, you should include a detailed problem statement that explains your client's pain points, challenges, and gaps with data and evidence. Next, you should provide a high-level explanation of your solution to address the problem, the deliverables you will provide, and the outcomes you will achieve. Following that is a breakdown of the specific tasks, activities, methods, and resources involved in your solution along with the timeline, milestones, and responsibilities. Then you can present your pricing and terms clearly and transparently. Lastly, a strong call to action should be included to invite your client to take the next step.
