At some point in the production process, the question shifts from how the book is printed to where it actually goes. Those are different questions, and conflating them is one of the more expensive mistakes a small press can make. The platform you print through determines the channels through which the book can be ordered — and those channels determine whether a bookstore buyer can put it in their system, whether a librarian can order it through standard acquisitions, and whether the book has any presence in the trade at all.

The two POD platforms most publishers are weighing are IngramSpark and KDP Print. They’re not interchangeable, and understanding why means understanding where each one’s distribution actually reaches.

Bookstores Order From Ingram, Not Amazon

This is the fact the whole decision turns on: bookstores do not order from Amazon’s supply chain. They order from Ingram.

Ingram Content Group is the largest book distributor in North America and the backbone of the wholesale trade network. When a bookseller logs into their ordering system — Edelweiss, the Ingram iPage catalog, their POS system’s order interface — they’re pulling from Ingram’s catalog. A book that exists only on Amazon’s supply chain is, from a bookstore’s perspective, essentially not available for ordering through normal channels.

IngramSpark is Ingram Content Group’s publisher-facing POD and distribution platform. When you publish through IngramSpark, your title enters Ingram’s wholesale catalog — the one booksellers and librarians actually use. A buyer at an independent bookstore can order it the same way they order any other title. A librarian can order it through standard acquisitions. The book is, in the fullest sense, in the trade.

KDP Print is Amazon’s POD platform. It produces excellent books, the retail relationship with Amazon is strong, and titles appear as in-stock with Prime-eligible shipping. But the distribution is Amazon’s supply chain, not Ingram’s. A bookstore that wanted to order your KDP-only title would have to do it through Amazon directly — which no bookstore does at scale, because the trade terms are wrong and the workflow doesn’t integrate with how stores actually buy.

What IngramSpark Costs, and Why the Framing Matters

IngramSpark charges a setup fee: $49 per title per format (paperback, hardcover, and ebook are separate). That fee is frequently waived during promotions, and IngramSpark runs promotions often enough that it’s worth checking before you pay full price.

KDP Print has no setup fee.

This cost difference gets treated as a meaningful comparison, and it isn’t. The real comparison is trade access against no trade access, not IngramSpark’s $49 against KDP’s zero. If a novel is intended for bookstores and libraries, IngramSpark is the platform that puts the book in the channels that matter for a serious press launch, not an optional upgrade. The $49 is just a line item on the printing budget, not the real question.

The real question is discount structure. IngramSpark requires a minimum 40% wholesale discount for non-returnable titles. For bookstore stocking — not just catalog-availability, but actually showing up on a shelf — you’ll want to offer returnability, which means setting the discount at 55%. That’s standard trade terms. It affects your per-unit margin, and it’s worth calculating before you finalize your retail price. But it’s also just how the book trade works. If you want the trade, you work within its terms.

KDP Print’s “Expanded Distribution” Is Not the Same Thing

KDP offers an “Expanded Distribution” option that routes your book into Ingram’s catalog at a reduced royalty rate. If you’re publishing exclusively through KDP and not using IngramSpark, it gives you some catalog presence in the trade. But the royalty rate is lower than what you’d receive going direct through IngramSpark — and if you’re running IngramSpark simultaneously, you’re creating channel overlap on the same wholesale network with worse economics on the KDP side.

The practical rule: if you’re using IngramSpark, do not enable KDP Expanded Distribution.

The Hybrid Setup: Running Both Platforms

A serious press launch typically runs IngramSpark and KDP Print simultaneously on the same title. This is the standard approach, and it’s workable once you understand the one configuration that makes it function cleanly.

The problem with running both platforms without configuration is that IngramSpark will list the book on Amazon through its own distribution channel, and KDP Print will also list the book on Amazon. Two suppliers, same marketplace, same ISBN — Amazon resolves this in ways that can create price inconsistency, fulfillment confusion, and suppressed Buy Box behavior.

The fix is straightforward: in IngramSpark, suppress the Amazon channel. IngramSpark allows you to opt out of specific distribution territories and channels. You remove Amazon from IngramSpark’s distribution list, which means IngramSpark handles the trade — bookstores, libraries, international retail networks — and KDP Print handles Amazon exclusively. Clean separation, no channel competition.

This setup requires matching trim sizes across both platforms. Standard literary trim sizes — 5.5 × 8.5 and 6 × 9 — work on both IngramSpark and KDP Print without problems. Both platforms will need your cover file and interior file, but each has its own bleed and margin specifications, so expect to prepare platform-specific versions of each file rather than a single file that works universally.

The Decision, Simply

This setup applies to POD publishing. Offset print runs involve a different distribution arrangement and are covered separately.

For a novel with bookstore and library ambitions, IngramSpark is not optional. The trade runs through Ingram. KDP Print is a strong complement — Amazon is a meaningful retail channel — but it doesn’t replace trade distribution.

For a title intended primarily for Amazon, with no ambition toward independent bookstore placement or library acquisition, KDP Print alone is adequate. The economics are simpler, the setup is faster, and if the audience is primarily Amazon-native, the trade channel isn’t where they’re buying.

For a press launch — a title positioned as a serious literary publication, aimed at a trade audience — the hybrid configuration is the standard. IngramSpark for the trade, KDP Print for Amazon, distribution channels cleanly separated.

Sort the distribution setup before you finalize your retail price — the wholesale discount affects your per-unit margin at every price point. And before you order proof copies: both platforms need their own file versions, and trim or margin issues are cheaper to catch on a proof than after a retail listing is live.

Distribution isn’t a checkbox at the end of production — it’s the part that determines whether the book actually reaches the places you’ve been planning to reach. Sort out the channels before the files are final.
