IngramSpark vs KDP: Which One Should Print Your Book?

Every week an author asks us to pick a winner between IngramSpark and KDP, and every week the honest answer is the same: they are not competing for the same job. KDP is a shop window on the biggest bookstore on earth. IngramSpark is a distribution network that puts your book into the catalogs bookstores and libraries actually order from. Most professional indie authors use both. The real questions are which one leads, what each costs you per copy, and what traps to close before you upload anything.

Distribution: where the book can be sold

KDP sells on Amazon, superbly. Its Expanded Distribution option technically reaches other retailers and libraries, but in practice those channels order through Ingram anyway, the margins through Expanded Distribution are thin, and many bookstores will not stock a book whose supply chain runs through their biggest competitor. If your world is Amazon, KDP alone is a complete answer.

IngramSpark plugs your book into Ingram's wholesale catalog, which is how Barnes & Noble, independent bookstores, libraries and thousands of online retailers order print books. A bookstore will rarely special order a KDP only title. It will order an IngramSpark title at standard terms without blinking. If you dream of your book on physical shelves, or pitch libraries, IngramSpark is not optional.

Money: setup, print cost and royalty math

KDP charges nothing to set up a title and takes its cut in the royalty: on Amazon you earn 60% of the retail price minus printing costs. IngramSpark has historically charged a setup fee per title and fees for file revisions after approval, though it runs free setup promotions often enough that it is worth checking before you upload. With Ingram you set a wholesale discount, and bookstores expect the standard trade discount (plan around 55%) plus returns enabled, which lowers your per copy earnings further.

A worked example, using realistic numbers for a $16.99 paperback: on KDP via Amazon, 60% of $16.99 is about $10.19, minus roughly $4.50 printing, leaves about $5.69 per copy. The same book through IngramSpark at a 55% wholesale discount leaves 45% of the price, about $7.65, minus a similar or slightly higher printing cost, so around $2.50 to $3 per copy before any returns. Amazon copies pay better. Everywhere else pays something instead of nothing. That is the whole trade in one paragraph.

The returns question nobody warns you about

IngramSpark lets you choose whether bookstores can return unsold copies. Enable returns and bookstores order with confidence, but you pay the wholesale cost of every returned book, and a bad season can bill you for dozens of copies. Set the book non returnable and you are protected, but some stores order less or not at all. Our standard advice: launch non returnable (set to "No" or return via publisher destruction where offered), build demand first, and revisit returns only when a real retail opportunity asks for them. KDP has no equivalent risk on standard sales, which is one more reason it is the safer place to start.

Print quality, formats and speed

KDP prints well and ships fast, and its proof copies arrive in days in the US. IngramSpark's print network is larger globally, its color printing has the longer professional reputation, and its hardcover program is more complete: case laminate and dust jacket options, more trim sizes, where KDP hardcover is a smaller menu. Authors publishing illustrated books, cookbooks or bookstore targeted hardcovers usually feel the difference first. IngramSpark revision fees also punish sloppy files: upload final, proofed files, because every post approval change costs money there.

One more structural difference: ISBNs. If you use KDP's free ISBN, that edition can only live on KDP. Buy your own ISBNs (in the US, from Bowker) and the same paperback edition can exist on KDP and IngramSpark under the same ISBN, which is how the two platform strategy is normally built. We set this up as part of publishing company setup work precisely because untangling ISBNs later is misery.

So which order should you publish in?

For most authors: KDP first, IngramSpark second.

1. Publish the paperback and ebook on KDP with your own ISBN. Amazon starts earning while everything else is prepared.
2. Order the physical proof, fix what paper reveals, and finalize the files.
3. Set up the same edition on IngramSpark with the same ISBN, wholesale discount at trade standard, returns off at launch.
4. Skip KDP's Expanded Distribution once IngramSpark is live, so the same retailers are not offered the book twice on worse terms.

Use IngramSpark first instead when the launch is bookstore and library led (local author, regional topic, speaking circuit) or when the book is a hardcover or color interior that KDP's menu cannot do justice. And if your book is going to Lulu for special formats, that is a third pattern again; our Lulu cover template guide covers the production side of it.

FAQ

Can I use both KDP and IngramSpark for the same book? Yes, and most established indie authors do. You need your own ISBN, and each format (paperback, hardcover) keeps the same ISBN across both platforms.

Is print quality better on IngramSpark? For color work and hardcovers, IngramSpark has the stronger reputation and the wider options. For standard black and white paperbacks, both print well, and KDP wins on proof speed.

Does IngramSpark distribute ebooks too? Yes, but most authors keep the ebook on KDP (optionally in Kindle Unlimited) and use IngramSpark for print distribution. Splitting print and ebook strategies is normal.

What discount should I set on IngramSpark? Bookstores expect trade standard, around 55% off retail. Lower discounts raise your per copy royalty but quietly reduce ordering. Set the price and discount together, not one at a time.
