Questions for a formatterFormatting is one link, and the chain is the cost
A dedicated formatter does its job well. Before you buy one, ask each vendor how it handles revision after layout, the audiobook, each translated edition and the second formatting pass a translation needs, and which file you take away at the end. Any of those steps that starts again somewhere else is part of the real cost.
Folio keeps the book production workflow together: draft and revise chapters, run the consistency audit or a focused editorial pass, validate an ISBN you already hold and generate its barcode, and export EPUB, editable DOCX and a print-ready interior PDF. Freeze an edition and review its actual proof before preparing an author handoff. Audiobook and international edition services use the same source book through their separate access and purchase workflows; you review each result.
Keep the chapter plan, source passages, recorded review and frozen proof with the same book. When the files are ready, you upload them to the distributor you choose. Specialist editing, design, rights review and destination requirements may still need outside work.
Folio validates an ISBN you already hold, converts between ISBN-10 and ISBN-13, and generates the barcode for your print cover. It does not issue ISBNs. Folio prepares downloadable book files; it does not publish them to a retailer, provide human copyediting, or guarantee publishing or commercial outcomes.
Buy formatting software first ifThe draft is already final
If the manuscript has already gone through revision and the main work left is layout, typography, and distribution formatting, formatting software is the right first purchase.
That is especially true if the draft was written elsewhere and already approved.
Buy Gixo Folio first ifThe manuscript still needs planning, drafting, or review
If the book still needs structure, chapter development, revision, export selection, or edition planning, the workflow tool should come first. That keeps the manuscript, export, and later localized editions connected.
For many nonfiction buyers, that means they may not need a second tool at all.
Book formatting softwareWhat book formatting software actually does
Book formatting software takes a finished manuscript and turns it into files you inspect against store or printer requirements. In practice that is five jobs: interior layout and typography, chapter and section styling, trim size and margins for print, front and back matter, and export to a reflowable EPUB plus a print-ready PDF. It is a presentation tool, and a good one is worth having when presentation is the problem that is left.
Atticus combines writing and formatting in a browser-based product. Vellum focuses on formatting on macOS. Both can prepare book files; compare platform support, editing, and interior controls with a sample manuscript rather than assuming a formatter cannot support writing. Checked 6 November 2026 against both vendors' sites, linked below.
That scope is also why a formatter can be bought too early. Layout tools do not finish an unfinished manuscript, so buying one for layout alone before the draft is stable can mean paying for a tool that waits while the writing continues elsewhere. If the product also has a writing editor, as Atticus does, test that editor on your own draft first.
When you can skip itDo you need book formatting software at all?
Not always. If your destination accepts a reflowable EPUB or a standard print-ready PDF, which covers most ebook stores and most print-on-demand paperbacks, the export built into a manuscript workspace is usually enough. Gixo Folio exports EPUB, editable DOCX, chapter PDF, HTML, and Markdown without an active subscription, including static SCORM, so for a straightforward text-driven book the second purchase is often unnecessary.
Where dedicated formatting software still earns its price: illustrated or heavily designed interiors, unusual trim sizes, box sets and omnibus editions, and any book where the typography is part of the reading experience rather than a container for it. If that describes your book, buy the formatter — but buy it after the manuscript is done, not before.
