How to Write a Business Book: A Step-by-Step Guide

Most people who want to write a business book already know the steps. Idea, outline, draft, edit, publish. The lists are everywhere, and they are not wrong.

What the lists rarely say is that the steps are decisions, and each one depends on the one before it. Choose the reader after you have drafted three chapters and you will rewrite all three. Plan chapters before you know what material you have and the plan will ask for stories you cannot tell. In our view, most stalled business books were not abandoned for lack of discipline. They were started at the wrong step.

So this guide is a map: eight stages in the order the decisions depend on each other, each kept short, with a link to the deeper article. If you have no idea where to begin, skip to “Start here this week”.

The eight stages on one page

Each row is one decision, with a test for knowing you have made it.

Stage	The decision	You are done when	Go deeper
1. Idea	What the book does for your business	You can name the paid next step it leads to	Business book ideas for coaches
2. Reader	Who exactly it is for	You can describe one real person, not a demographic	Thought leadership books
3. Promise	What changes for that reader	You can finish “This is the first book that…”	Creating a framework
4. Material	What you already have and what is missing	Every document is in one folder, gaps listed	Extract your knowledge first
5. Plan	Chapters, order and the job of each	Each chapter answers one reader question	Outline template
6. Draft	Who writes, when, and from what	A complete first draft exists, however rough	Writing a chapter
7. Review	Is every claim true and every chapter yours	Facts checked, voice consistent, editor engaged	Editing with AI
8. Publish	Route, launch and use in your business	The book is in the hands of the reader from stage 2	Publishing a business book

Our main-site guide, how to write an authority book, walks a similar sequence in eight detailed steps with a book brief. Read it for depth; use this page to see where you are.

Stages 1 to 3: idea, reader and promise

These three take the least time and cause the most rewriting when skipped. Josh Bernoff, who coaches business authors, ran a 2024 study of about 300 respondents, mostly published authors, and found that 34% had no gross profit from their book. He names four causes: unclear goals, no clear audience, no differentiation and no marketing. He also warns that the study probably flatters books, because people with failed projects rarely fill in surveys (Bernoff, April 2025). Three of those four causes are settled, or not, before you write a page.

Stage 1: tie the idea to your business

Bernoff is blunt about this: “The only realistic reason to write a business book is to boost your own business” (Bernoff). We agree, with one adjustment. The idea should sit directly under something you already sell. A book on a topic you do not get paid for is a hobby, and hobbies get dropped in busy quarters.

Write one sentence: “When someone finishes this book, the natural next step is ___.” If the blank is “book a pricing review”, you have an idea. If it is “feel inspired”, keep going. Turning expertise into a book helps if you have too many candidate ideas.

Stage 2: one reader, described as a person

“Small business owners” is not a reader. Bernoff’s advice in his reader question method is “Don’t just define your audience, personify it”. Pick a real former client, privately, and write down their role, the problem that brought them to you, what they had tried and what they feared.

Stage 3: a promise you can defend

The promise is what changes for that reader. Bernoff’s test for differentiation is a good one: can you truthfully finish the sentence “This is the first book that…”? If every ending you write could sit on ten books already on Amazon, your promise is too broad. Narrow the reader or sharpen the method until it cannot.

A hypothetical example. Imagine a sales coach who has spent eight years helping founder-led software companies hire their first salespeople. Her idea: a book that leads to her sales-hiring diagnostic. Her reader: a technical founder at roughly $2 million in revenue who has already hired and fired one salesperson. Her promise: “This is the first book that shows founders why their first sales hire fails before the job ad is written.” That took an afternoon, and it ruled out half the chapters she had planned.

Stage 4: gather what you already know before you write

Most experts with ten years of client work are not short of material. It is scattered: a keynote deck, two webinar recordings, client session notes, three years of newsletters. The job here is collecting it in one place and seeing what it covers.

Make a simple inventory: document, date, what it says, which reader question it answers, and whether you are allowed to use it. Client material needs care; client stories and case studies covers permission and disguise. Recordings are often the richest source because they hold your spoken voice; see turning talks and webinars into a book.

The inventory will show gaps. Write them down rather than filling them. A missing case study is better discovered now than invented in chapter six.

Stage 5: plan the chapters as the reader’s questions

The most useful planning idea we know is Bernoff’s: “You should build your table of contents around the questions your reader will ask.” He describes a typical sequence: why should I care, why should I trust you, how should I think about this, the practical how-to questions, and what the future looks like (Bernoff). Experts tend to organise by how they think; readers want to know what to do and why.

On length, Bernoff writes that “many business books consist of eight to fifteen chapters” and that a typical nonfiction book runs 40,000 to 80,000 words. How-to books can work with more, shorter chapters of 1,000 to 2,000 words grouped into parts (Bernoff). Ten good questions make ten chapters.

For each chapter, write one line on the question it answers and list the material from stage 4 that answers it. Our business book outline template gives you the format, and how to structure a business book covers order and parts. If your material spans decades, start with organising years of experience into chapters.

Software can do part of stages 4 and 5. WritebookAI, for example, analyses the PDF, Word and text files you upload (or notes you paste), shows what the material covers and what is missing, and asks you about conflicts and gaps in a verification interview before building a book strategy and chapter plan with beat sheets. It does not choose your goal or reader for you, and the plan is only as good as your documents. A book coach or an afternoon with index cards does the same job by hand.

Stage 6: draft from the plan, in your own voice

Drafting is where the hours go. The most detailed public record we found is from Mo Bunnell, who logged every 15-minute block of his traditionally published book, The Snowball System. Planning and the first draft took 255 hours. Revisions took 62.5 and the copy edit 71.5, so 389 hours went on the manuscript itself. The whole project, including the book proposal, agent search, blurbs, audiobook and launch preparation, came to 813.25 hours (Bunnell Idea Group). That is one author and one route; a self-publisher skips the roughly 158 hours spent on the proposal and agent.

You have three ways to produce the draft: write it yourself in fixed weekly blocks, hire a ghostwriter who interviews you, or use AI, which only helps if it works from your own documents and writing samples. Given a general prompt, AI returns the consensus your readers have already read. We compare the routes in AI book writer vs ghostwriter, and writing a book with AI in your own voice covers keeping it sounding like you.

Two opinions. Write the introduction last, once you know what the book says. And do not edit while you draft: a rough complete draft is worth more than three polished chapters, because only a complete draft shows you what the book is. If your calendar is the problem, writing a book when you have no time has realistic weekly schedules.

Stage 7: review in separate passes

Read the draft three times, each time for one job.

1. Claims. Every number, result and quote needs a source you can produce, especially if AI touched the draft; see stopping AI inventing facts.
2. Structure. Does each chapter answer its question from the plan? Cut what does not.
3. Voice. Do chapters two and nine sound like the same person? Our guide to consistent voice across chapters has a routine for this.

Then pay a professional editor. We would spend on editing before design every time: a beautiful cover on a muddled argument does more harm than a plain cover on a sharp one. Two readers who resemble your stage 2 reader are worth more than ten colleagues.

Stage 8: publish, then put the book to work

Choose a route: traditional, hybrid or self-publishing. For most coaches and consultants we would self-publish, because speed and control matter more than bookshop distribution for a book whose job is to start client conversations. Our guides on publishing a business book and publishing on Amazon KDP cover the choice and the mechanics.

If you publish on KDP and used AI, check the rules. As of November 2026, Amazon’s content guidelines require you to disclose AI-generated text, images or translations, and count text as AI-generated “even if you applied substantial edits afterwards”. AI-assisted work, where you wrote it and used AI to edit, refine or brainstorm, does not need disclosing. You are responsible for both.

Then remember Bernoff’s fourth failure cause, no marketing. Plan how the book reaches your stage 2 reader before launch; see how to market a business book and using a book to attract clients.

Start here this week

If you still do not know where to begin, do this. Five sessions of about an hour, one per working day. No chapters.

Monday: the business sentence. Finish “When someone finishes this book, the natural next step is ___.” Write three versions and keep the one closest to what you already sell.

Tuesday: the reader. Describe one former client in a paragraph: role, problem, what they tried, what they feared. Do not use their name anywhere but your own notes.

Wednesday: the promise. Write ten endings to “This is the first book that…”. Cross out any that describe a book you have already read. Keep the best one.

Thursday: the folder. Put every talk, deck, recording, article, course module and set of client notes you can find in an hour into one folder. Do not read them yet.

Friday: the questions. List the ten questions your Tuesday reader would ask you, in the order they would ask them. That list is your first table of contents.

All five ticked? Go to stage 4 and start the inventory. If one is blank, that is next week’s job, and a better use of the time than drafting.

Stuck later? Go back one stage, not forward

Books stall at stage 6 for reasons that started earlier. Before you blame your discipline, find your symptom.

Symptom	Usually starts at	What to do
Every chapter feels like it could go anywhere	Stage 2, no single reader	Rewrite the reader paragraph, then reread the plan
The book sounds like every other book on the topic	Stage 3, weak promise	Rerun the “first book that” test
You keep stopping to look for an example	Stage 4, no inventory	Build the inventory and list the gaps
Chapters overlap or repeat each other	Stage 5, chapters not tied to questions	One question per chapter; merge or cut
You have rewritten chapter one five times	Stage 6, editing while drafting	Freeze it and draft chapter two
The draft is done but you dread sending it out	Stage 7, unchecked claims	Do the claims pass, then hire the editor

Our guide to finishing the book you have been planning goes further on restarting a stalled draft.

Find your row in the first table, settle that one decision, and only then move on. If you are at the very beginning, Monday’s sentence takes ten minutes. Write it today.
