KDP vs IngramSpark vs Hybrid Publisher: How to Pick Your Path in 2026
By Abdul Moeed
If you have a finished manuscript in 2026, you have three real paths: upload it yourself to Amazon KDP, upload it yourself to IngramSpark, or hire a publishing service such as Nova Publishers to do the work in your own accounts. Nova Publishers is one of those services. Here is what each path involves and where it fits.
Path 1: Amazon KDP: fast and Amazon first
On KDP you upload the files yourself, and your book goes live on Amazon (Kindle plus paperback POD), usually within a few days. You upload an EPUB, a print PDF, a cover, set the price, and it's live.
Where KDP fits: Speed. Royalties of 35% or 70% on Kindle ebooks, depending on price, and 60% of list minus printing on paperbacks sold on Amazon. Direct ads via Amazon Advertising. Easy series setup.
Where KDP stops: Distribution. KDP Print is technically also available through Expanded Distribution, but bookstores and libraries rarely order through it. If you want bookstores and libraries to be able to order your book, IngramSpark is the usual route.
KDP on its own suits you if: Your readers buy almost entirely on Amazon, your files are already edited and print-ready, and you want to learn the platform yourself.
Path 2: IngramSpark: broader distribution, steeper learning curve
IngramSpark lists your book in the Ingram catalog, the wholesale channel most bookstores and libraries order from. They handle paperback, hardcover, and ebook (with distribution to Apple Books, Kobo, Barnes & Noble, and others).
Where IngramSpark fits: Hardcover with dust jacket, a returns option (which most physical bookstores expect), and library distribution.
Where IngramSpark takes work: Setup. The platform expects you to know what trim size, paper type, spine width, and barcode placement you want. A file with the wrong bleed or spine width gets rejected, and fixing it means another round of uploads and proofs.
IngramSpark suits you if: You want bookstores and libraries to be able to order your book, or you want hardcover editions, and you are comfortable with print specs, discounts and returns settings.
Path 2b: Both KDP and IngramSpark
Many indie authors do both: KDP for the Kindle edition and the Amazon paperback, IngramSpark for the bookstore-distributed paperback and the hardcover. The ISBN KDP assigns only works on Amazon, so if you use both, an ISBN you own (or one from your publishing service) keeps the editions consistent.
Path 3: A publishing service: pay for the team, keep the rights
A real publishing service (some call it a hybrid publisher) does the editing, design, formatting, ISBN and distribution work for a fixed fee, and you keep 100% of your retailer royalties. (If they also take a percentage of your retailer royalties, that's a vanity press. Walk away.) You ship them a manuscript, they ship you a published book in retail and audiobook channels.
What a publishing service gives you: Time. Quality control. Dealing with KDP and IngramSpark on your behalf. Audiobook production, which is the hardest piece to do yourself. Working with first time authors who have not yet learned the full self publishing toolchain.
What it costs: Nova Publishers' packages run from $999 to $5,499 as one fixed quote, and from Launch Pro they include a launch marketing plan, because even great production needs a real launch.
A publishing service suits you if: Your manuscript is finished, you want to spend your time writing the next one (or running your business), and you do not want to learn KDP and IngramSpark interfaces yourself. Especially worth it for first time authors and authors with day jobs.
How to actually decide
Ask one question: What is my time worth? Doing it yourself means learning KDP and IngramSpark, hiring an editor and a designer, and running the schedule between them. A full-service publisher like Nova Publishers does all of that in your own accounts for one fixed quote, so those hours go back into writing your next book.
The wrong answer is always vanity press. If anyone offers to 'publish' your book in exchange for a fee plus a long term royalty split, they are taking your money twice and your book once.
