Understanding the Service
What is Developmental Editing?
Developmental editing — also called structural editing — addresses the big picture of your manuscript. Rather than focusing on language at the sentence level, it examines argument, structure, chapter organisation, logical flow and narrative coherence across the entire text.
It is the most in-depth editorial service available and is typically carried out before copyediting or proofreading. For authors whose draft is complete but whose manuscript needs strategic reshaping before submission, developmental editing provides the framework to transform a strong draft into a compelling, publishable work.
Ideal for
Non-fiction authors, academic book authors, researchers with complex manuscripts, and writers preparing a book proposal or full manuscript for submission to a publisher.
Typically €40–€60 per 1,000 words, depending on the manuscript’s length, complexity, and the level of editorial input required. Project-based pricing is also available for ongoing or multi-stage editorial support.

Developmental Editing
“Developmental editing doesn’t rewrite your book — it shows you how to make it the book it is meant to be.”

Frequently Asked Questions
What is the difference between developmental editing and copyediting?
Developmental editing addresses the big picture — structure, argument, flow and coherence. Copyediting works at the line level — grammar, clarity and style. Developmental editing always comes first, before any language work begins.
Is developmental editing suitable for academic manuscripts?
Yes — developmental editing is particularly valuable for academic monographs, edited volumes, and postdoctoral manuscripts being prepared for academic publishers. Dr. Sarah's PhD background means she engages deeply with complex theoretical and interdisciplinary texts.
Will developmental editing change my argument or ideas?
Never. Developmental editing works with your argument — identifying how to present it more clearly, logically and compellingly. Your ideas, interpretation and scholarly perspective remain entirely yours throughout.
How long does developmental editing take?
A full book manuscript typically takes 3–6 weeks depending on length and complexity. The timeline is confirmed before work begins so you can plan your revision and submission schedule accordingly.
