How to Hire a Book Editor
Hiring a book editor is one of the most consequential decisions you'll make as a publishing author. Get it right and you gain a strategic thought partner who makes your book significantly better — someone who can become a trusted collaborator across every book you publish from here on out. Get it wrong, and you're out thousands of dollars, months of time, and possibly your confidence as a writer.
The problem is that most authors don't know what they don't know when they start looking. They're evaluating editors based on vibes and price when there's a whole set of criteria — timing, experience, process, fit — that would tell them so much more.
This is your complete guide to hiring a book editor: what kind of editing you actually need, where to find qualified candidates, what to expect to pay, when to start looking, and the ten questions to ask before you sign anything.
First: figure out what kind of editing you actually need
Before you start looking for an editor, you need to know what you're looking for. "Editing" is not one thing — it's a spectrum of distinct services, and the right editor for one stage of your manuscript is not necessarily the right editor for another [link to "The difference between developmental editing, line editing, and proofreading"].
Here's the short version:
Developmental editing works on the big picture — structure, argument, narrative arc, chapter organization, and whether your book is actually doing what it needs to do for your reader. This is the edit that shapes the book.
Line editing works at the paragraph and sentence level — clarity, flow, voice consistency, and the quality of the prose itself.
Copyediting handles grammar, syntax, punctuation, and consistency. This is the technical polish pass.
Proofreading is the final read before publication — catching anything that slipped through everything else.
Most nonfiction manuscripts need developmental editing before anything else. If the structure isn't working, fixing the grammar is rearranging furniture in a house with a cracked foundation. Know what your manuscript needs before you start reaching out to editors, and look specifically for someone who specializes in that service.
Where to find a book editor
Once you know what type of editing you need, here's where to actually find qualified candidates.
Professional directories. The Editorial Freelancers Association (EFA) maintains a searchable member directory of vetted professionals across every editing specialty. If you want to work with someone who takes the craft and business of editing seriously, this is a good place to start.
Referrals from other authors. Ask in the author communities, writing groups, or nonfiction publishing spaces you're already part of. A recommendation from someone who has worked with an editor firsthand is worth more than any directory listing — you're getting a real account of what the working relationship actually looks like.
The editor's own platform. Many independent editors build their businesses through content, newsletters, or social media. If you've been reading someone's perspective on books and writing and it resonates with you, that's a meaningful signal worth following. Trust is built before you ever get on a call.
Your existing network. A direct ask — in a LinkedIn post, a Substack note, or a DM to an author you admire — goes further than most people expect. "Who edited your book and would you recommend them?" is a question most authors are genuinely happy to answer.
What to avoid: editing mills, bargain platforms that compete entirely on price, and anyone who promises a fast turnaround on a full manuscript without having read a single page of your work first.
What does it cost to hire a book editor?
Editing costs vary depending on the type of editing, the length and complexity of your manuscript, and the editor's experience level. Here are realistic ranges for a full-length nonfiction manuscript:
Developmental editing: $0.08–$0.15+ per word ($4,000–$10,000+ for a full manuscript)
Line editing: $0.06–$0.12 per word
Copyediting: $0.03–$0.07 per word
Proofreading: $0.02–$0.04 per word
Some editors price by the project rather than per word, and some offer packages that bundle multiple services. Always request a quote based on your specific manuscript length before budgeting.
One note on price shopping: the least expensive editor is rarely the best investment. Professional editing is exactly that — professional. The quality of feedback you receive from an experienced editor who specializes in your type of book will not be replicated by someone charging a fraction of the market rate. That said, price alone is not a proxy for quality either. Ask the questions below before you commit to anyone at any price point.
When to start looking for a book editor?
One of the most common mistakes authors make when putting together their publication team is waiting too long to start. Many professional editors who specialize in a particular genre or type of book are booked out months in advance.
The general rule: start reaching out when your manuscript is about ninety percent complete. Not fully polished, not through multiple rounds of beta readers — just mostly written. That gives you a realistic sense of your manuscript's length and scope, enough context for a substantive conversation with a potential editor, and enough lead time to get on the calendar of the person you actually want to work with rather than whoever happens to be available.
If you wait until your manuscript is completely finished before you start inquiring, you may find yourself rushing to hire someone who isn't the right fit simply because the timeline demands it. Don't let availability make that decision for you.
10 questions to ask before you hire a book editor
Some editors prefer to communicate by email or have you complete an intake questionnaire. Others will jump straight to a video call. If a discovery call isn't offered and you want one, ask for it. Editing is a close working relationship and you should talk to this person — ideally on video — before you hire them.
Here are the ten questions that matter most.
1. What's your training and professional background?
You're not looking for a specific degree — you're looking for evidence that this person has invested seriously in the craft and business of editing. That might be a degree in English, publishing, or creative writing. It might be a professional editing certificate or continued education through an industry association. What matters is that they can speak specifically to how they developed their skills and that they're actively staying current with publishing trends and standards.
Vague answers about always loving books are not a substitute for professional development.
2. How long have you been working as an editor, and what kinds of books do you typically work on?
Experience matters — but so does the right kind of experience. An editor who has spent a decade working primarily in fiction may not be the right fit for a nonfiction business book built around your framework or your body of expertise. Ask how long they've been working professionally and dig into the specifics: what genres, what types of authors, what stages of manuscript development. Ask to see their portfolio or client list if it isn't already visible on their website.
3. What type of editing do you specialize in?
A strong developmental editor is not automatically a strong copyeditor, and vice versa. Know what type of editing your manuscript needs before you get on the call, and confirm that the editor genuinely specializes in that service — not just lists it as an offering [link to "What type of editing does my book actually need?"].
4. Do you have experience working with authors at my stage?
There's a meaningful difference between editing for a debut author who has never written a book and editing for a thought leader who has published before and knows what they want. Some editors specialize in first-time authors. Others prefer working with writers who already have a strong draft. Be honest about where you are in your process and ask whether they regularly work with authors at that stage.
5. Do you have experience in my genre or category?
Genre conventions are real. A memoir has different structural expectations than a framework-driven business book. A prescriptive self-help title operates differently than a narrative nonfiction book. Your editor should understand the category you're writing in — not just editing in general. If they've worked on books similar to yours, they'll be able to tell you what works, what readers in your category expect, and where your manuscript is or isn't meeting that bar.
6. What does your editing process actually look like?
A professional editor should be able to walk you through their process clearly: how they read your manuscript, how and when they deliver feedback, what the revision cycle looks like, and what happens after they return their edits. This is also the moment to ask about their feedback philosophy. Are they directive or collaborative? Do they explain the reasoning behind their suggestions or just mark up the page? Will you receive a revision letter, tracked changes, an editorial memo — or some combination?
Knowing what to expect before you're in the middle of it makes the whole process significantly less stressful.
7. What's your fee structure, and what's included?
Clarify exactly what you're paying for before you sign anything. Does the quoted price include a revision round? What happens if your manuscript runs longer than estimated? Are there additional fees for a follow-up call, a query letter review, or proofreading? Professional editors are transparent about their pricing. If you're getting vague answers or feeling pressured to commit before you have clear numbers, pay attention to that [link to "Red flags to watch for when hiring a book editor"].
8. Can I see a sample edit?
Many editors will complete a short sample — typically five to ten pages — before you commit to a full project, either as a complimentary service or for a small fee. Read the sample carefully. Does their feedback make your writing better? Does it feel like they understood what you were trying to do? Do you feel energized or deflated reading their notes? All of that is useful data, and it's the clearest signal you'll get before signing a contract.
9. Why do you want to work on this book?
By the time you ask this, the editor should have enough context about your manuscript to answer it meaningfully. You're not looking for flattery — you're looking for genuine engagement. An editor who can speak specifically to what drew them to your premise, your voice, or your subject matter is an editor who's paying attention. That attention is what you're paying for.
If the answer feels generic, it probably is.
10. Do you work with a contract, and what does it cover?
The only acceptable answer is yes. A professional editor will always provide a written agreement that outlines scope of work, timeline, deliverables, fee structure, revision policy, and cancellation terms. A contract protects both of you. If an editor balks at providing one, walk away. This is non-negotiable.

Frequently Asked Questions
What is the best way to find a book editor?
Start with professional directories like the Editorial Freelancers Association, ask for referrals from authors you respect, and look for editors who create content in the publishing space — someone whose perspective resonates with you before you've even spoken is a meaningful signal. Always schedule a discovery call or video meeting before hiring.
How much does it cost to hire a book editor?
Costs vary by service and manuscript length. Developmental editing typically runs $0.08–$0.15+ per word. Line editing runs $0.06–$0.12 per word. Copyediting is generally $0.03–$0.07 per word, and proofreading $0.02–$0.04 per word. Always request a project-specific quote before budgeting.
When should I start looking for a book editor?
Start reaching out when your manuscript is about ninety percent complete — not fully finished. Many professional editors book out months in advance, and starting early gives you time to find the right fit rather than defaulting to whoever is available.
What's the difference between developmental editing and copyediting?
Developmental editing addresses the big picture: structure, argument, narrative arc, and whether the book is working for the reader. Copyediting addresses the technical layer: grammar, syntax, punctuation, and consistency. Most manuscripts need developmental editing before copyediting — always in that order.
Do I need a contract when hiring a book editor?
Yes, always. A professional editor will provide a written agreement covering scope of work, timeline, fees, revision terms, and cancellation policy. A contract protects both parties and is a non-negotiable mark of a legitimate professional working relationship.
What should a sample edit tell me?
A sample edit shows you how an editor engages with your specific writing — where they push back, what they prioritize, and how their feedback voice lands. Does their feedback make your writing better? Do you feel energized or deflated? The right editor's notes should make you want to keep going.
How do I know if an editor is the right fit for my book?
Beyond credentials and process, pay attention to how they talk about your specific book. Do they engage with your premise and voice, or does their feedback feel generic? Do they have real experience in your genre? Does the relationship feel collaborative? The right editor makes you want to keep writing — not question whether you should have started.
