Self-Publishingon Amazon KDP & Beyond

Full publishing setup across all major platforms — you keep 100% of your rights and every royalty you earn.

Your book is edited, formatted, and covered. Now you need to publish it. The actual process — creating accounts, configuring metadata, choosing categories, uploading files, and getting everything approved — is more involved than it looks. And the decisions you make at this stage (which platforms, which categories, KDP Select or wide distribution) have real consequences for your royalties and discoverability. We handle the entire process, configure it correctly, and make sure you understand every decision before it's made — because it's your book, and you should be fully satisfied with how it goes out into the world.

What is self-publishing?

Self-publishing is the process of distributing your book directly through retail platforms — primarily Amazon KDP, but also Barnes & Noble Press, Apple Books, Kobo, and others — without a traditional publisher acting as intermediary. Self-published authors retain all rights to their work and receive royalties directly: typically 35–70% on ebook sales depending on price and market, and around 60% of the print list price minus production costs on print-on-demand titles. Opus Publishing Co. handles the technical publishing process on your behalf. You retain ownership of your account, your book, and every royalty it generates. For the best results, your files should be professionally formatted and your cover should be designed for the platform before upload.

Who is this for?

Authors with formatted files ready to publish who find the platforms confusing

KDP's interface has improved, but configuring metadata, categories, and keywords correctly is not intuitive — and the decisions you make here have real consequences for discoverability. We set everything up correctly from the start.

Authors who published before but want professional metadata and keyword setup

Many authors who published their first book by themselves left discoverability on the table — wrong categories, unused keywords, weak descriptions. We can update existing listings or get your next book set up the right way from launch day.

Writers going wide for the first time

Publishing across Amazon, Apple Books, Kobo, and Barnes & Noble involves four separate platform interfaces, each with its own requirements. We manage the full process and make sure your book is correctly configured everywhere it goes live.

Our process

  1. 01

    Submit your files and publishing brief

    Send your formatted manuscript files and cover (or we prepare them as part of a bundle). Tell us your preferred platforms, pricing goals, and whether you want KDP Select or wide distribution.

  2. 02

    Metadata preparation

    We write or refine your book description, research the optimal categories and keywords for your genre, and prepare all metadata for each platform. We share everything with you for review and approval — nothing goes live until you've seen it and confirmed it's right.

  3. 03

    Upload and configuration

    We handle all the platform logistics — uploading your files, configuring pricing, categories, and keywords, and submitting for platform review. We manage any back-and-forth with platform support, and keep you updated at each stage so you always know where things stand.

  4. 04

    Live confirmation

    We confirm when your book goes live on each platform and send you direct links to your published listings. Your royalties start flowing to your account from day one — it's your book, your account, and your earnings.

Frequently asked questions

Yes — 100%. We publish your book to platforms where you own the account and receive all royalties directly. Amazon KDP pays ebook royalties of 35% or 70% depending on pricing (70% applies to books priced between $2.99 and $9.99 in most markets). Print royalties vary by page count and trim size. We never take a cut of your royalties — you pay us a one-time service fee for publishing setup.

It depends on your goals. Amazon KDP is the dominant platform — it has the largest reader base and the best self-publishing royalty structure. Publishing exclusively on KDP through KDP Select gives you access to Kindle Unlimited. Publishing wide (KDP plus Apple Books, Kobo, and Barnes & Noble) reaches readers who prefer other platforms. We'll discuss your goals and recommend the right distribution strategy for your book.

KDP Select is Amazon's exclusivity program: you agree to publish only on Amazon for 90-day periods, in exchange for enrollment in Kindle Unlimited (where you earn based on pages read) and access to promotional tools like Kindle Countdown Deals. Wide distribution means publishing on all platforms simultaneously — Amazon, Apple Books, Kobo, Barnes & Noble, and others. KDP Select works well for authors with large Amazon-focused audiences; wide distribution is better for building a platform-independent reader base.

KDP provides a free ASIN for ebooks and a free ISBN for print books if you choose that option. However, a KDP-assigned ISBN is owned by Amazon, not you. If you want an ISBN that identifies you as the publisher — which is important for library distribution and some bookstore channels — you'll need to purchase your own or we can suuply you with the required ISBNs.

Once we have your formatted files, cover, and metadata, we complete the publishing setup in 1–3 business days per platform. Amazon KDP review typically takes 24–72 hours after upload. Apple Books and Kobo can take 3–5 business days to go live. We provide estimated live dates for each platform at the time of upload.

KDP ebook distributes your book as a digital file for Kindle devices and apps. KDP print is print-on-demand: a physical copy is printed and shipped to each buyer, with no upfront print run required. Most authors publish both. They require different formatted files — an EPUB for ebook and a print-ready PDF for the interior, plus a full-wrap cover PDF for print. We handle both.
