Ask five authors what "editing" means and you may get five answers. One thinks of fixing commas. Another imagines a wise mentor reshaping the plot. Both are describing real jobs, but they are different jobs, done at different times, by people with different skills. Understanding the stages helps you spend your budget in the right order and avoid paying to polish text you later cut.

Stage one: developmental editing

Developmental editing looks at the whole book. For fiction, that means plot structure, pacing, character arcs, point of view and whether the ending delivers on the opening. For non-fiction it means the logic of the argument, the order of chapters, gaps in evidence and whether the book serves its intended reader.

The output is usually an editorial letter, sometimes with chapter notes, rather than a marked-up manuscript. It tells you what works, what does not and what to prioritise. If you suspect something is wrong with the middle of the book but cannot say what, this is the stage you need. Our developmental editing service follows this approach.

Stage two: line editing

Once the structure is settled, line editing works on the prose itself. A line editor improves rhythm, trims repetition, sharpens word choice and makes sure each paragraph does its job. The aim is a more fluent, confident version of your own voice, not a different voice. This is also where dialogue is tuned so it sounds like speech.

Line editing comes after developmental editing because there is little point polishing a chapter you may remove. You can read more about what this involves on our line editing page.

Stage three: copy-editing

Copy-editing is the technical clean-up: grammar, punctuation, spelling, usage, consistency of names, numbers and hyphenation, and checking that facts and timelines do not contradict one another. A copy-editor keeps a style sheet recording every decision, so that "e-mail" does not become "email" halfway through the book.

Some editors combine line editing and copy-editing into one pass. That can work well for clean manuscripts, but it is worth confirming with your editor exactly what is included so you are not surprised.

Stage four: proofreading

Proofreading happens last, on the designed pages. A proofreader compares the final layout against the edited text and looks for typos, spacing errors, broken headings, awkward line breaks and missing page numbers. Proofreaders do not rewrite. If a book skips editing and goes straight to proofreading, they will find many problems that the proofreading stage was never designed to fix.

Our proofreading service works at this final stage, and our fact-checking service can be added earlier for non-fiction.

How to decide what your book needs

  • Unsure if the story or argument works: start with developmental editing.
  • Structure is solid but the prose feels uneven: book a line edit.
  • Prose is strong, but you want it clean and consistent: copy-editing.
  • Everything is edited and designed: proofread before you upload.

Not every book needs all four stages, and budgets are real. If you can afford only one, ask for a sample edit from two or three professionals and choose the stage that would improve your book the most. An honest editor will tell you which one that is.

A final thought

The right order matters as much as the right editor. Big changes first, small changes last. When each stage builds on the one before it, your book gets better at every step, and you spend your money where it makes the most difference.
