A Developmental Edit gives you the detailed, structural report of a manuscript assessment but on a deeper, more in-depth level.

Get detailed, structural feedback from a professional book editor

Our Developmental Editing Service provides the same level of rigour you would expect from a Big-Five publishing house.

Undertaking a developmental edit will get your work into the best possible shape to submit to agents or to self-publish, and you’ll get to experience the process of working with a professional editor.

Don’t take just our word for it…

We’ve been helping writers achieve their goals for over 20 years. Here’s what some of them had to say about our editorial services:

I’m so glad I found Jericho Writers. I had been looking for developmental editing on my manuscript and found the very, very best.

Claire W

Developmental Editing customer

The critique I received from Jericho Writers was instrumental in my eventual offer of representation. The feedback lit a spark of ideas in me that meant I was able to overhaul the whole book in the right way to get an agent’s attention. I cannot recommend it highly enough.

Charlotte O

Manuscript Assessment customer

I couldn’t be more delighted with the results. My editor gave me so many amazing suggestions and some much needed

Allison M

You kindly gave me some excellent feedback on the initial stages of my novel. Well, it’s “finished”, and I have been fortunate to have it shortlisted for the Wilbur Smith Foundation Award for Adventure novel of the year (unpublished).

Richard F

Your comments on the random points of view in my opening paragraph left me stunned! I take all your advice gratefully, and all of the technical points like POV, tense, dialogue, etc., went straight on the to do list.

Steve K

Opening Section Review customer

Thank you again for your encouragement and many brilliant suggestions for my Cuba novel. I found them very perceptive and incorporated them into another draft.

Marion D

Thank you so much for thorough feedback, kind words and encouragement. It means a lot. I found your report very clear and it sparked many ideas

Aman K

I remain impressed by both the quality and the quantity of Liz’s work. Apart from the overall comments, she goes into such great detail, character by character, chapter by chapter, missing nothing.

Carmella A

I was also blown away with your encouragement and thoughtfulness. You have given me excellent advice on how to focus on not only the query and synopsis, but also the plot. I encourage other writers to use your service.

Milo P

Thank you for your perceptive and incisive report. I’ve been desperate for help like this and so much wish that I had found Jericho Writers a few years ago.

Richard F

Editorial customer

Pippa’s very clear report was full of encouraging, knowledgeable advice on how to improve the reader experience of the picture-book texts I sent her. Also, because I’m a newcomer to the world of children’s publishing, she filled me in on what the market is like at the moment.

Frequently asked
questions

1

How should I format my manuscript?

Please use an easy-to-read font like Times New Roman, 12pt. Don’t forget to also number your pages and use double spacing.

2

How long will it take to match my manuscript with an editor?

We aim to match you with the right editor within 2-4 days. We’ll get back to you as soon as the choice has been confirmed.

3

How do you choose the editor?

We match manuscripts based on over 20 years of experience working with our editors. We consider editor experience, their genres of interest, and whether they themselves feel they are the right fit for your work. As all our editors are freelance, this depends on availability.  

4

Can I choose my editor?

If you have a particular editor in mind, we will of course do our best to match you with them. We cannot guarantee this, however, as all of our editors are freelance and there are times when they are unavailable due to demand and/or other commitments.

Once you have placed your order, you’re welcome to send a shortlist of 4-5 editors from our website (and we’ll do our best to place you with your preferred editors).

5

What if my book is good enough? Will you help me find an agent?

On some occasions, an editor will flag a manuscript as submission ready. When this happens, a member of the Jericho Writers team will look at the author’s agent submission pack and provide some free advice on it, plus access to AgentMatch. On some occasions, where the manuscript shows real promise, we’ll also approach agents on the author’s behalf.

It’s worth noting however, that this service is reserved for manuscripts which editors believe have strong commercial potential and are of a very high quality. Please don’t be disappointed if yours isn’t selected – most manuscripts require quite a few rewrites before reaching submission standard!

6

Which editorial service is right for me?

We offer quite a few editorial services, so you’re right to take the time to consider all of your options. The writing process is a long one, so whether it’s line editing or copy-editing, or something on a larger scale, like a manuscript evaluation or developmental edit, we have the service for you. You can take a look at all of our editorial services here. You might also like to read our article explaining all the different types of editorial services. If you’re still not sure, feel free to get in touch with us and we’ll be happy to offer more advice.

7

How and when do I submit my manuscript?

After purchase, we’ll invite you to upload your full manuscript via our online submission form. Once we’ve received your submission, we’ll get back to you as soon as we’ve matched your work up with the right developmental editor.

8

How do I know if a developmental edit is the right choice for my manuscript?

We recommend our developmental editing service if:  

  • Your manuscript is in pretty good shape (ie: this should be the last major round of work before submitting to publishers or self-publishing the manuscript). 
  • You want both broad and narrow comments. 
  • You want the opportunity to talk at length with one of our developmental editors. 
  • You are OK paying for a premium service. 

We recommend a manuscript assessment if: 

  • Your manuscript is still at a somewhat earlier stage in its journey. 
  • You feel able to handle the narrower issues yourself, so long as you have reasonable guidance from your manuscript assessment report.   
9

What does a developmental editor work on?

The developmental editing process looks at both the broad and the small aspects of a manuscript. Your professional developmental editor will write a long written report containing structural commentary that looks at the big picture elements of your story, such as themes, characterisation, and your narrative arc. Developmental editing involves the more minute details too (like sentence structure, unclear dialogue, and grammar), and our freelance developmental editors provide page-by-page feedback along with annotations on the manuscript itself.

10

What is the difference between substantive and developmental editing?

Developmental editing is also called substantive editing, and the two services are now generally considered to be one and the same. Though this hasn’t always been the case. While developmental editors focus on both large and small scale edits, substantive editors have traditionally dealt with improvements made at the scene, paragraph, and sentence levels. However, the terms are now largely used interchangeably, with both offering enhancements that can be made on a small and a large scale.
