How to write a nonfiction book proposal: sections, template and a worked example
A nonfiction book proposal is the business case for your book, and it is how most nonfiction is sold to a traditional publisher, usually before the book is written. It has seven standard parts, and each one has to prove a single thing. Here is what each must prove, a fill-in template for every section, and a worked example.
Who needs a book proposal
Anyone who wants a traditional publisher to buy a nonfiction book. Novels are generally sold as finished manuscripts. Nonfiction works the other way round: as Jane Friedman, a long-time publishing industry writer and educator, explains in her guide to book proposals, a nonfiction author can sell the book before writing much of it, and if the proposal persuades a publisher, it contracts and pays the author to write it.
Two exceptions. A first-time memoir writer is often judged on the writing itself, so agents may ask for the full manuscript as well. And a finished manuscript does not replace a proposal: if an agent asks for one, write one.
Not sure traditional publishing is right for you? Stage 10 compares all four paths.
What a proposal is for
A publisher that buys your book is taking a financial risk on something that does not exist yet. The proposal has to win three yeses:
- Will people buy this? A clear group of readers has a need, and evidence shows they buy books like this.
- Can this author reach them? You already have ways to put the book in front of those readers.
- Can this author deliver? The structure is sound and the writing is good enough.
Test every paragraph against those questions. If it answers none of them, cut it. The classic failure: pages on what the book is about, none on why it will sell.
| Section | What it must prove | Your raw material in this guide |
|---|---|---|
| 1. Overview | The book is worth publishing, now | Stage 2 promise |
| 2. About the author and platform | You are the right person, and you can reach readers | Stage 9 bio, expanded |
| 3. Target readers | A specific group needs this and buys books | Stage 1 reader profile |
| 4. Comparable titles | Readers like yours already buy books like this | Stage 2 Amazon research |
| 5. Marketing plan | You will sell copies yourself | Your existing audience and channels |
| 6. Chapter outline | The book is complete and well built | Stage 3 outline |
| 7. Sample chapters | You can write it | Stages 6 and 7 |
The seven sections, one at a time
1. Overview
What it must prove: the book has a sharp idea, a clear reader and a reason to exist now. It comes first, but write it last, once the other sections have forced you to decide what the book really is.
Common mistakes: opening with your life story; calling the book "comprehensive" as if that sells it; saying it is for everyone.
Template: overview
Hook: [A fact, story or question your reader recognizes from their own life.]
The problem: [What your reader struggles with, in their words, and what it costs them.]
The book: [Title: Subtitle] is for [specific reader]. It shows them how to [result] by [your method or insight].
Why it is different: [What existing books miss, and what yours does instead.]
Why now: [What has changed that makes this book needed today.]
Why you: [One line on your expertise and reach. Detail goes in section 2.]
2. About the author and platform
What it must prove: you have earned the right to write this book, and you can reach its readers. Your platform is the people you can already reach: an email list, clients, a podcast, talks, media, an organization you lead. For business and how-to books it can matter as much as the idea.
Common mistakes: pasting in your website bio; listing every achievement rather than the relevant ones; describing an audience you hope to build; giving no numbers anyone could check.
Template: about the author
Credibility: [Your role and the experience that taught you what the book teaches.]
Proof: [Results, clients, research or recognition a stranger could verify.]
Reach today: [Each channel with its current, real number: subscribers, followers, downloads, talks last year and audience size.]
Relationships: [Organizations and well-known people who know your work and could help.]
3. Target readers
What it must prove: a specific, findable group needs this book and buys books. Describe the readers who will buy first and tell others, not every possible reader.
Common mistakes: huge, meaningless numbers (a country's population, a topic's search results); a demographic with no need attached; several unrelated audiences in one book.
Template: target readers
Primary reader: [Role, situation and the moment they would reach for this book.]
What they want: [The result they are after, in their words.]
Where they gather: [Associations, conferences, publications, podcasts, communities.]
Evidence they buy books: [Books they already read and recommend. This feeds section 4.]
4. Comparable titles
What it must prove: readers like yours already buy books like this one, and yours offers them something new. Comparable titles ("comps") are not rivals to beat; they are evidence a market exists. How to choose them is below.
Common mistakes: claiming there are no comparable books (to a publisher, that means no buyers); only famous mega-bestsellers; old or obscure books with few reviews; harsh criticism of the comps.
Template: one comparable title (repeat for each)
Details: [Title: Subtitle], [author], [publisher], [year], [format], [page count], [price], [ISBN].
What it does well: [Briefly and generously.]
Who reads it: [How its readers overlap with yours.]
How yours differs: [What your book adds for the same reader, and why that matters.]
5. Marketing plan
What it must prove: you will sell copies, with resources you already have. The Scribe Method calls this the most important section, because publishers count on the author to drive sales. Write only what you can and will do, with names and numbers.
Common mistakes: "I would be willing to" and "I hope to"; a long list of ideas unconnected to any existing audience; promising media you have no contact with.
Template: marketing plan
Your own channels: [Each channel, its real size today, and exactly how you will use it at launch.]
Speaking: [Talks held or booked each year, typical audience, and whether books can be sold or included.]
Bulk sales: [Organizations or clients that could buy copies in quantity, and any that have said they would.]
Partners and endorsers: [People and organizations who have agreed to share the book, by name.]
6. Chapter outline with summaries
What it must prove: the book is thought through from first page to last, every chapter earns its place, and the whole keeps the overview's promise. List each chapter with a working title and a short summary.
Common mistakes: summaries that only name a topic ("Chapter 4 is about hiring"); chapters making the same point twice; a book that is strong for three chapters and then fades.
No outline yet? The free outline builder takes you through five proven structures and asks for each chapter's point, story and takeaway. Those three answers are most of a chapter summary.
Template: one chapter summary (repeat for each)
Chapter [number]: [Working title]
[One sentence stating the chapter's point.] [One or two sentences on the story, case or evidence that proves it.] [One sentence on what the reader can do differently by the end.] [Optional: how it leads to the next chapter.]
7. Sample chapters
What it must prove: you can write the book you described. Include one or two polished chapters. For a teaching book, choose the chapter that best shows your method at work, not the introduction. For memoir or narrative, start at the beginning.
Checklist: sample chapter
[ ] It is a core chapter that delivers on the book's promise, not a warm-up.
[ ] It stands on its own without the chapters before it.
[ ] It has been revised the way Stage 7 describes, structure first and sentences last.
[ ] A reader who matches your target reader has read it and can say what it taught them.
How to choose comparable titles
Good comps prove a buying market and show where your book fits. Do this research first; it may reshape the idea.
Search the way your reader would
Use your reader's words, not your jargon. Note every book a reader with this problem might buy instead of yours.
Keep the recent, successful ones
Favor books from the last several years, from established publishers, with plenty of reviews and signs they still sell.
Read the middling reviews
Three-star reviews are where readers say what was missing. If they keep asking for what your book does, say so in your "how yours differs" lines.
Mix the closeness
Include books on the same problem for the same reader, and books that share your reader but tackle a neighboring problem.
Describe each fairly
Say what each does well, then what yours adds. The author you criticize may be published by the editor you are pitching.
Decision rule: if you cannot find any successful comparable books, do not write "there is nothing like it." Either readers describe the problem in other words (search again), or they do not buy books about it (rethink the idea, and test it as Stage 2 describes).
A worked example
This example is fictional. We wrote it for illustration; the book, the author and her clinics do not exist. It shows an overview paragraph and two chapter summaries for a teaching book.
Example overview paragraph (fictional book)
Most physical therapy clinic owners open a second location for the same reason: the first one is full. Many then discover that what made the first clinic full was them. The Second Location: How to Grow a Clinic Without Cloning Yourself is a practical guide for owners of single-site practices who are ready to expand but cannot be in two places at once. Drawing on her own expansion from one clinic to four, Dr. Maya Okafor shows readers how to turn what lives in their head into systems, choose and train a clinic director, and decide with real numbers whether a new site is ready to open. Existing practice-management books cover marketing and billing well; none walks a clinical owner through the moment of letting someone else run a clinic with their name on the door.
Example chapter summary
Chapter 3: Write down what you do without thinking. Before anyone else can run a clinic the way you do, your way has to exist outside your head. The chapter follows Okafor's first attempt at a second site, which stalled when new staff kept phoning her for decisions she had never explained. Readers leave with a one-week method for capturing their daily judgment calls and turning the most frequent into written rules a director can follow.
Example chapter summary
Chapter 6: Hire the director before the lease. Signing for space first and finding a leader second is the costliest order to do things in. Through two owners who did it in opposite orders, the chapter shows what a clinic director needs to be good at and how to test for it before making an offer. It ends with an interview guide and a ninety-day handover plan, setting up Chapter 7 on the numbers that say a new site is ready.
Each summary states the point, names the proof and says what the reader can do afterward.
Length and format
There is no official length. Jane Friedman's guide gives useful ranges: most proposals run about 10 to 25 double-spaced pages before sample chapters; the overview is about two to three pages; comps typically cover 5 to 10 books at roughly 100 to 200 words each; and she suggests keeping the chapter outline under about 3,000 words. Follow any length or format an agent or publisher asks for.
If you plan to self-publish
You do not need to send a proposal to anyone. Work through its core sections anyway, because each forces a decision your book needs:
- The overview becomes your back cover copy, your retailer description and your answer when someone asks what the book is about.
- Comparable titles show where your book sits on the shelf, what it should not repeat, and which categories fit it.
- The marketing plan becomes your launch plan. If it is thin, better to learn that now, while there is time to fix it.
- Chapter summaries become your writing brief, and the best document to hand an editor, coach or ghostwriter.
Self-publishing lets you skip the proposal. It does not let you skip the thinking behind it. If you would like to talk a book plan through with people who publish books for a living, Scribe offers a free consultation.

The Scribe Method, Scribe's free book on writing and publishing, has a chapter on how to write a nonfiction book proposal, including why publishers ask for proposals rather than manuscripts, with a downloadable template.
Common questions
Do I need to finish my nonfiction book before writing a proposal?
Usually not. Nonfiction is typically sold on a proposal and one or two sample chapters, and the publisher pays you to write the rest. Memoir is the main exception: a first-time memoir writer may be asked for the full manuscript too.
How long is a nonfiction book proposal?
There is no fixed rule. Jane Friedman says most run about 10 to 25 double-spaced pages, not counting sample chapters, and complex projects can pass 50 pages with the chapters included.
How many comparable titles should a book proposal include?
Jane Friedman's guidance is typically 5 to 10, or fewer for a specialized or niche topic. Choose recent books from known publishers that your reader would actually buy, and never claim there are none.
Do I send my proposal to publishers or to a literary agent?
For the large traditional publishers, to an agent, who pitches it for you. University presses, regional and independent presses and niche publishers often do not require an agent. Follow each agent's or publisher's own submission guidelines.
Is a book proposal worth writing if I plan to self-publish?
The document is optional; the thinking is not. Working through the overview, readers, comparable titles, marketing plan and chapter summaries forces the decisions that make a book clear, and gives you a brief for any editor or writer you hire.
