Meet Your Metrics: The 3Cs of Book Proposals (with Debra Eckerling!)

How to write a nonfiction book proposal: the 3 sections every publisher wants to see

If you've been sitting on a book idea for months or years because you think you need to finish the whole manuscript first, here's the part nobody tells you early enough: most nonfiction books are sold via book proposal, not a completed draft. You need a clear idea, a plan for execution, and proof that people will buy it. That's the document that gets you in front of agents and publishers.

A book proposal makes the case for why your book will sell and why you need to be the one to write it. It's part business plan, part writing sample, part marketing strategy. And it breaks down into three sections that are a lot less intimidating than most people assume.

Here's what actually goes in a nonfiction book proposal and why each section matters.

Concept: what is this book and why does it need to exist

The first section of a book proposal is about the book itself. What is this thing, what makes it different from everything else on the shelf, and why are you the right person to write it.

This section typically includes an overview (the pitch for your book in a few pages), a summary of what's inside, and book specs like estimated word count and timeline. Think of it as the answer to a very specific question: if someone picked this up in a bookstore, why would they buy it instead of the five books next to it?

This is also where your passion has to come through. You're going to be talking about this book for a long time if things go well, so it needs to be a topic you genuinely care about. Agents and publishers can tell the difference between someone who wrote a book because they had something to say and someone who wrote one because they thought they should.

Context: who you are, who will buy it, and how you'll sell it

The second section is about you and your audience. It starts with your author bio and photo, because publishers are investing in you as an author, not just your manuscript.

Then comes your author platform. This doesn't mean you need a million followers. It means showing where you already have presence and credibility, online and off. A newsletter, a podcast, speaking engagements, board memberships, community involvement. One author landed an agent primarily through her offline presence: she sat on the board of five organizations full of her ideal readers. That was enough.

After platform comes your marketing plan. This is where you show that you're willing to partner with the publisher on getting the book out there. You're not expecting them to do all the work while you collect royalties. You're showing skin in the game.

The section wraps up with audience research (proof that readers for this topic exist and are buying) and comp titles. Comp titles are books similar enough to yours that the same reader would want both, but different enough that your book fills a gap the others left open. If you're struggling to find your differentiator, start with comp titles. Seeing what's already out there often reveals exactly where your book fits.

Content: the table of contents, outline, and sample chapters

The final section is the most straightforward. It includes a table of contents, a detailed outline with a paragraph or two about each chapter, and two to three sample chapters. Usually that means the introduction plus one or two chapters that best represent the book's voice and structure.

This is referred to as the writing sample, though realistically the entire proposal is a writing sample. By the time you're done, you'll have written 30 to 50 pages, and those pages double as the roadmap for writing the actual book. That's not a small point. One book proposal expert wrote all three of her traditionally published books in under three months each, because the proposal had already mapped out every chapter.

What a book proposal actually costs you (less than you think)

There are a lot of inflated numbers floating around the publishing world. Six-figure price tags for book deals. Claims that the process takes three or more years. Requirements of 125,000-word manuscripts before you can even begin.

Most of that is either outdated, exaggerated, or coming from people who want to sell you something expensive. A book proposal is a document you can build over time. The investment is your effort, your expertise, and the willingness to actually plan before you write. You don't need a massive platform. You don't need a completed manuscript. You don't need $100,000.

You need a good idea, proof that readers exist, and a clear plan on paper. That's what gets you in the room.

If you're a small business owner with a book idea that keeps tapping you on the shoulder, and you're not sure whether the concept would land with a real audience, that's exactly what Will This Sell? is for.
