You typed "The End" three weeks ago and you still haven't opened the file since. That's normal. After a year with the same characters, you literally cannot see the sentences anymore. This is the exact moment a book editing service earns its fee, and it's also the moment most writers underestimate how much editing there actually is.
People hear "editing" and picture someone fixing commas. That's a sliver of it. A real edit works in layers, and knowing which layer you need saves you money and a lot of frustration.
The three edits are not the same job
A developmental edit looks at the whole thing: does the plot sag in the middle, does your protagonist want something clear enough to carry a reader for 300 pages, do the chapters land in the right order? No one touches your commas here. They're asking whether the book works.
A line edit comes next. This is about how each sentence sounds — rhythm, repeated words, a character who says "actually" nine times a page. Then, last, proofreading catches the typos and the stray double space. If you pay for a proofread when what you needed was a structural edit, you'll get a clean copy of a book that still doesn't work. Ask any editing service which stage they're quoting for.
Why order matters
Proofreading a chapter you're about to cut is wasted money. Always fix the big things first, then work down to the small ones. A good editor will tell you honestly if your manuscript isn't ready for a line edit yet.
What you should get back
Beyond the tracked changes, you want an editorial letter — a few pages that explain the pattern behind the fixes. "Your dialogue is strong but you keep explaining the joke in the next sentence" is worth more than a thousand isolated corrections, because it teaches you to catch it yourself next time.
You should also get a style sheet: the record of how names are spelled, whether you use the Oxford comma, that your world calls it "the Council" and not "the council." This keeps a 400-page book internally consistent, which readers feel even when they can't name it.
How to brief an editor well
Tell them the genre and the audience up front. A cozy mystery and a literary novel get edited by different instincts. Say what you're worried about — "I think chapter twelve drags" — because editors read differently when they know where you already feel the weak spots. And be honest about your deadline. A rushed edit on a 90,000-word manuscript is rarely a good one.
If you can, send a short sample first and pay for a test edit of ten pages. You'll learn quickly whether this editor gets your voice or wants to rewrite you into someone else. That fit matters more than the hourly rate.

The part writers dread
Good editing stings a little. When an editor flags a scene you loved, the instinct is to defend it. Sit with the note for a day before you reply. Usually you'll find they were right about the problem even if you disagree about the fix — and the fix is yours to make, not theirs. That's the deal: they diagnose, you decide.
The manuscript that comes back won't be someone else's book. It'll be your book, with the fog cleared. That's the whole point of hiring a book editing service — not to sound like everyone else, but to sound like the best version of you, on every page.
