Book coach vs editor: which do you need, and when?
A book coach works with you while the book is being decided and written. An editor works on pages that already exist. If you have no draft, you almost certainly need a coach (or a plan) first. If you have a full draft, you almost certainly need an editor. Many books need both, in that order.
Different points in the process
The simplest way to tell the two apart is to ask: does the help start before the pages exist, or after?
- Idea. You know roughly what you want to say. Coach territory.
- Plan. Reader, promise, table of contents, chapter outline. Coach territory.
- Drafting. Months of writing, revising as you go. Coach territory.
- Full draft. Beginning to end exists. Developmental editor.
- Revision. You rework the book based on the edit. Editor's letter as the map; a coach can help if you stall.
- Line and copy edits, proofreading. Sentences, consistency, errors. Line editor, copyeditor, proofreader.
A coach's work is front-loaded and ongoing. An editor's work is concentrated on a finished (or nearly finished) manuscript. That difference in timing drives almost every other difference between them.
What a developmental editor does
The Editorial Freelancers Association describes developmental editors (also called substantive, structural or content editors) as dealing with "content, organization, and genre considerations." Their output is usually either a manuscript evaluation, which is an overall critique, or an editorial letter that lays out the big problems and suggests how to fix them, often with comments in the manuscript itself.
In practice, a developmental editor reads your whole book in one sitting or close to it, the way a reader would, and answers questions like:
- Does the book deliver what the introduction promises?
- Is the order right, or does chapter seven need to come third?
- Where does the argument repeat, wander or skip a step?
- Which chapters are carrying the book and which are padding?
- Is anything missing that the reader will need?
That fresh, whole-book read is the editor's main value. It is also the one thing a coach who has been with you through every chapter cannot really give.
What a book coach does
A coach helps you get to a draft worth editing. That means settling the reader and the promise, building the outline, setting a writing rhythm, reading pages as they come, and keeping you going through the long middle. The coach's feedback is incremental: this chapter, this week. Read what a book coach does for the full picture.
Side by side
| Book coach | Developmental editor | |
|---|---|---|
| Starts | Before or during drafting | Once a full draft (or most of one) exists |
| Main job | Shape the book and get it written | Diagnose a finished manuscript and show how to fix it |
| Works on | Ideas, outline, chapters as they arrive, your process | The manuscript as a whole |
| Rhythm | Ongoing: calls and page reviews over weeks or months | Concentrated: one deep read, then a letter and notes |
| Typical output | A plan, a table of contents, a chapter outline, a draft you wrote | An editorial letter or evaluation, often with comments in the manuscript |
| Who writes | You | You (the editor suggests; you revise) |
| How it is priced | Per session, monthly, or as a package | Usually per word, per hour or per project |
| Best for | Stuck on structure or momentum, first-time authors, stalled projects | Finished drafts, experienced writers, anyone about to publish |
| Main limit | Too close to the book to judge it cold | Cannot help much until the pages exist |

When you need both
You probably need both if two or more of these are true:
- You do not have a full draft yet, and you plan to publish the book, not just write it.
- This is your first book.
- You have stalled before, so you need help getting to the end, and you also want a professional verdict once you are there.
- The book will represent you or your business, so the quality bar is high.
In that case the order is almost always coach first, editor second. A developmental edit on half a book wastes money: the editor cannot judge the structure of something that does not exist yet, and much of what they comment on will change anyway.
An example of the usual order
A consultant has years of client talks and a folder of notes but no chapters. She hires a coach for a few months. Together they settle the reader (operations leaders at mid-sized firms) and the promise, build a twelve-chapter outline, and she drafts on a weekly schedule. When the draft is done, she hires a separate developmental editor, who reads it cold and says chapters three and nine make the same case and the last third loses the reader. She revises with the editor's letter, then the book goes to a copyeditor and a proofreader.

When the order flips
If you already have a complete draft, start with the editor, even if you also want coaching. The editor's letter tells you what the revision needs to do. Then decide whether you can carry out that revision alone or want a coach to keep you moving through it. Revisions are where a lot of finished drafts quietly stall, so this is a reasonable place to bring in a coach.
When you need only one
Only a coach, at least for now: you are early, the problem is shape or momentum, and you will decide about editing once there is a draft. Many coaching engagements end with a plan or a draft and a recommendation to hire an editor next.
Only an editor: you have finished long work before, you have a full draft, and what you want is a professional, independent read. Paying for months of coaching would buy you support you do not need.
Neither yet: if you have the hours, like writing alone and want to keep costs low, write the draft first and budget for an editor at the end. The tool will tell you if your answers point this way.
Questions to ask either one
- What exactly will I receive, and when? (A letter, comments in the file, calls, a revised outline?)
- How many of my pages will you read, and how closely?
- Have you worked on books like mine (same kind of reader, same kind of argument)?
- Can I see a sample of your feedback, with the client's permission, or a short sample on my own pages?
- What happens if I disagree with your feedback?
- What is not included that I might assume is?
For a coach specifically, the full list of 24 first-call questions is in how to choose a book coach.
Still unsure which you need? The coach, editor or ghostwriter tool weighs where your manuscript is, how much feedback you want and your budget, and tells you whether to start with a coach, an editor, or both in order.
Common questions
Can my book coach also be my editor?
Sometimes, and many coaches have editing backgrounds. The trade-off is distance. A coach who watched every chapter being written is too close to judge the whole with fresh eyes. If you can afford it, a separate developmental editor at the end catches what you and your coach both stopped seeing.
What is a manuscript evaluation?
A lighter form of developmental editing. The editor reads the whole manuscript and writes a letter (often a few pages) on what works and what needs to change, without marking up every page. The Editorial Freelancers Association lists it as one form developmental feedback can take. It costs less than a full developmental edit and is a good first step.
Do I need a copyeditor if I had a developmental editor?
Yes, if you are publishing. Developmental editing deals with structure and content. Copyediting and proofreading catch errors in grammar, consistency and typing. They are separate jobs done at the end, usually by different people.
Is it worth paying for an editor if I am self-publishing?
For most nonfiction books, yes. Readers and reviewers notice structural problems and errors, and you cannot see them in your own writing. If budget forces a choice, a manuscript evaluation plus a careful copyedit covers the most ground.
