How to get feedback on your non-fiction book before you publish

Each rung costs more and sees more than the one below it, and none of them sees everything. Readers tell you where they got lost; editors tell you why. Start at the bottom, because each cheap fix leaves the expensive reader more time for problems only they can find. Prices are for an 80,000-word book. If you are not sure the draft is ready for anyone, run the ten-point readiness checklist first.

Self-editing is free and comes first: seven passes through your own draft, from structure down to sentences. It is the only rung where every fix costs nothing but time.

It catches what has a number. The middle half of bestsellers in The Anatomy of a Bestseller (47 books; 46 measured, the Bhagavad-gita being unscoreable) run 72,102 to 125,807 words, with chapters of 4,367 to 6,697 words and a reading grade of 8.3 to 11.3. You can measure all three alone, and you can search for every "studies show" that lacks a source. Paste a passage into the readability checker for its Flesch score and grade, and list each chapter's word count to see which run past one sitting.

It misses what you are too close to see: the step you skipped because you know it. Work through the self-editing checklist, then move up a rung.

Beta readers are ordinary readers who read the finished draft and tell you how it landed. Most are free, through swaps and critique groups. Paid beta readers charge 0.5–0.8¢ a word at the EFA's 2026 rates, a median of $150 a project; at those rates an 80,000-word book costs $400–$640 (our arithmetic).

They catch reactions no tool can: where a reader skimmed, which claim they doubted, what they would tell a friend the book is about. For non-fiction, recruit people who would buy the book, plus one expert if your subject is technical. Swap reads with other writers in a critique group if you have no budget. Never ask "did you like it?": people say yes to be polite. Ask where they stopped reading and which chapter they would cut.

They miss causes. A reader says chapter 6 dragged; they rarely say why or what to cut. Rounds take weeks and not every reader finishes. The beta readers guide lists where to find them, what each platform costs and a 15-question questionnaire.

The Manuscript AI report costs $19 and reads the whole manuscript (a Word file up to 16 MB) in one run, usually in under 10 minutes. It answers eight editorial questions: the main message, the writing style, flow between chapters, the author's personality, accessibility, chapter openings and closings, the reader's next step, and how easy the concepts are to follow.

For every chapter it gives a summary, recommendations, the word count, reading time, Flesch reading ease and Flesch-Kincaid grade. It also answers your own questions about the book. Set the chapter numbers against the bestseller bands above to see which chapters run long or read hard.

It does not fact-check, line-edit or tell you how a real reader feels. If you want feedback on one chapter, or rewrites, ChatGPT, Claude or Gemini will do that well. Your file is deleted within 48 hours of delivery and never used to train AI; how we keep your book safe has the detail. See a sample report on Atomic Habits before you decide.

An editorial assessment is an editor's letter on the whole book: what works, what does not and what to fix first, with no edits in the text. Editors report a median of $600 per assessment (EFA, all lengths). For an 80,000-word book, per-word rates come to $1,200–2,000: $1,200–1,440 at EFA rates and $2,000 at Reedsy's 2.5¢ average.

It catches what a reader cannot name: a structure that does not hold, an argument that skips a step, a chapter in the wrong place. Reedsy says a developmental edit "will typically cost 30% more than an assessment letter".

It misses the line level, and you make every change yourself. Turnaround is set by each editor, so ask for it in the quote. Ask too whether the editor reads the full manuscript or a sample of pages, and whether a call to discuss the letter is included. Read more on what a manuscript assessment covers and costs.

A developmental edit is the top rung: an editor works through the book's structure and argument with you. A developmental edit of an 80,000-word non-fiction book costs $3,200–4,000 at the EFA's 2026 median rates of 4.0–5.0¢ a word, and $2,080–4,240 on Reedsy.

It catches the most, because the editor reads closely enough to rebuild the book with you. It is the right buy when the cheaper rungs agree that the structure is broken and you cannot see how to fix it. Before you book, ask for the editor's non-fiction titles and an example of their notes, since developmental rates for business books run higher than for memoir on the EFA chart (4.5–6.0¢ against 3.5–4.5¢ a word).

It misses typos and consistency, which a copyedit and a proofread handle later. At EFA rates those cost $2,400–3,200 and $1,600–2,400 for 80,000 words. See what a developmental edit includes.

Get feedback cheap and fast first, slow and expensive last, and fix structure before sentences at every stage. Each round should change the draft before the next reader sees it, or you pay twice for the same note.

A 12-week runway looks like this:

1. Weeks 1–3: self-edit in seven passes.
2. Week 4: run the $19 report, then fix the structural notes.
3. Weeks 5–9: one round of three to five beta readers, with a deadline and one question per chapter.
4. Weeks 10–12: if the readers agree on a structural problem you cannot fix, book an assessment or a developmental edit and ask for its turnaround in the quote.

Tell every reader and editor what you want from them: structure, argument or reader reaction. Track every note in one spreadsheet, by chapter. When two sources flag the same chapter, fix it first; a lone complaint may be one reader's taste. If your launch date is closer than 12 weeks, keep the order and shorten each step.
