One of the advantages of being a nonfiction writer is that you can often sell a book on proposal—you don’t need to write the entire manuscript to find an agent or publisher. However, crafting a strong proposal can be just as challenging as writing the book itself. A proposal is about marketing and positioning as much as it is about the book’s content. So, what makes a compelling proposal? What do editors and agents expect, and how can yours stand out?

Below are key elements to include in a nonfiction book proposal. While these are common sections, feel free to adapt them to match your voice and style. Each proposal is unique, just like your book should be.

1. Overview

The overview should offer a clear and concise description of your book—think of it as your book’s pitch. Aim for one to two pages that summarise the essence of the project. This is your opportunity to grab the editor’s attention by highlighting the most intriguing points.

When writing your overview, think of it like an advertisement. What makes your book compelling? Why would someone want to read it?

Here are a few things to consider including:

  • Timeliness of the topic: Is it relevant to current events or trends?
  • Target audience: Who will buy this book, and how large is that market?
  • Unique angle: What sets your book apart from others on the same topic?
  • Approach: How will you present the material? Will there be special features such as charts, checklists, or photos?
  • Your platform: If you are a key selling point, be sure to mention your credentials and professional background.

2. Author Bio

Your author bio is one of the most critical elements of your proposal. Publishers want to know why you are the right person to write this book. It’s not just about expertise but also about your ability to reach readers through your platform.

When crafting your bio, highlight your most relevant qualifications first. Think about the accomplishments that give you credibility in the subject matter, such as:

  • Speaking engagements, workshops, or presentations you’ve given
  • Media appearances or articles in national outlets
  • Your social media following or newsletter subscribers
  • Any affiliations with influential organizations

Focus on what you’re currently doing to build your platform, and be specific about the reach and impact of your work. Don’t hesitate to include impressive details—whether it’s a column in Time magazine or a spot on a major radio show. This is not the time for modesty!

3. Marketing

After your platform, the marketing section is perhaps the most important part of your proposal. This is where you’ll demonstrate how your book will reach its audience. Editors are looking for authors who can actively contribute to the book’s success.

In this section, expand on your platform:

  • Speaking engagements: How often do you speak, and to how many people? Do you have upcoming events scheduled?
  • Media presence: Have you been featured in major publications? Include details and clips if relevant.
  • Social media and website: Do you have a blog, a newsletter, or social media following? If so, provide statistics on subscribers, followers, or traffic.

Don’t spend too much time on what you could do (like appearing on a national talk show) unless there’s a concrete plan in place. Focus on what you are already doing to build a readership. Publishers appreciate knowing you have existing momentum, not just ideas.

Additionally, you should include market data:

  • Market size: Provide statistics on the audience for your book, especially if it’s growing.
  • Demographics: Who will be interested in your book? Be specific.
  • Partnerships or endorsements: Do you have connections with organisations that will promote or purchase copies? Mention that here.

4. Competition

It’s essential to acknowledge the competition and explain how your book will stand out. Editors are often wary of too much or too little competition, so strike a balance here.

Identify two or three competing titles and clearly differentiate your book. What makes yours unique? Whether it’s your approach, your expertise, or the timeliness of your topic, make sure you explain why readers would choose your book over others. Demonstrating that you know your competition also reinforces your expertise in the subject matter.

5. Table of Contents (TOC) & Chapter Summaries

Your table of contents gives the editor a quick overview of your book’s structure. Make sure your chapter titles are clear and descriptive—cute or clever titles are fine, but they should also communicate what each chapter is about.

Chapter summaries are a crucial part of your proposal. They allow the editor to see how you’ll approach the material and give a sense of your writing style. Summaries should reflect the tone of your book and be engaging to read. Instead of saying, “Chapter One will cover…,” try to make each summary as lively and interesting as if it were part of the book itself.

For each chapter, mention any special features (charts, photos, case studies) you plan to include. Aim for one paragraph to a few pages per chapter summary, depending on how complex the material is.

6. Sample Chapters

Your sample chapters are the most important writing you’ll submit. These chapters should be polished, engaging, and representative of the book’s overall tone and style. Editors will judge your writing ability from these chapters, so make sure they shine.

Choose chapters that best showcase your strengths—don’t feel obligated to submit the first chapter unless it’s the strongest. Two to three chapters, or two chapters and an introduction, is typically sufficient. Avoid submitting too little material; it may give the impression that you’re not fully committed to the project.

7. Publicity

If you have past media appearances, press clippings, or articles you’ve written, include them in this section. If you’ve been interviewed or profiled on radio or TV, provide recordings or links. The more visibility you can show, the stronger your proposal will be.

Extra Tips to Keep in Mind:

  • Be Yourself: There’s no one-size-fits-all approach to a proposal. Use this guide as a framework, but make sure your unique voice and personality shine through.
  • Polish and Proofread: Typos, spelling mistakes, and sloppy grammar can undermine your professionalism. If writing isn’t your strong suit, consider getting help from an editor.
  • Details Matter: Include page numbers, author photos, and samples of any images or illustrations you intend to use.
  • Make Your Title Pop: The title is the first thing an editor sees, so make sure it’s both attention-grabbing and clear about the book’s content.

In the end, your proposal is your first and best chance to convince an agent or publisher that your book is worth publishing. Make it compelling, professional, and a true reflection of your expertise and passion.
