Amazon KDP Expanded Distribution vs. IngramSpark: What I Wish I’d Known Before Checking That Box

By The WhistlePig Team

When we first published some of our paperbacks through Amazon Kindle Direct Publishing (KDP), checking the Expanded Distribution box seemed like an easy way to reach more buyers. Why not make our books available beyond Amazon?

We did get a few sales through Expanded Distribution. Not many, but they were real. Later, as we worked to expand WhistlePig Publishing’s print distribution through IngramSpark, we learned that this seemingly small checkbox could complicate our plans.

This is our experience, not an argument that every author should avoid KDP Expanded Distribution. If you’re deciding how to distribute a paperback, here are the questions we wish we’d asked first.

What is KDP Expanded Distribution?

KDP Expanded Distribution is an optional program for eligible paperbacks. It can make a book available to distributors serving bookstores, libraries, and other retailers beyond Amazon. Available to order does not mean stocked on shelves, and enrollment does not guarantee sales or bookstore placement.

It can be appealing to an author who wants a simple print setup without opening another distribution account. But authors should compare the program’s royalty calculation, eligibility rules, ISBN arrangements, and future distribution plans before enrolling.

What happened at WhistlePig Publishing

We enabled Expanded Distribution on some of our KDP paperbacks. It resulted in a few orders, but it never became a meaningful sales channel for us. That’s a description of our results, not a prediction of anyone else’s.

As we began moving more of our print catalog to IngramSpark, we ran into an administrative complication: some of the titles we wanted to distribute through IngramSpark were already associated with KDP’s expanded-distribution channel. We had to address the existing distribution arrangement rather than simply assume we could use the same ISBN through another distributor immediately.

On October 19, 2026, IngramSpark support acknowledged our title-transfer request and wrote: “Please allow about 30 days for full completion. This allows time for us to obtain approval from the current publisher and allows for any orders to be fully processed before transferring.”

IngramSpark also said it would notify us when the transfer was complete. As of this article’s preparation, our transfer is still pending. The approximately 30-day estimate is what support told us about our request; it should not be treated as a universal deadline or a guarantee.

KDP Expanded Distribution vs. IngramSpark: what’s different?

Both routes can help make print books available beyond Amazon, but they aren’t identical services.

• KDP Expanded Distribution: Convenient if you already publish a qualifying paperback on KDP and want an additional distribution option without separately managing another print distributor. Expanded Distribution has its own royalty structure and does not promise retail orders.
• IngramSpark: A separate print-on-demand and distribution platform with its own setup, printing costs, wholesale-discount choices, and returnability decisions. Those settings can affect bookstore ordering and your profit—or potential costs—on each book.

You may be able to use KDP for Amazon paperback sales and IngramSpark for other print channels, but the same edition’s ISBN and distribution arrangements need to be handled correctly. A publisher-owned ISBN is particularly important to understand before you set up either platform. An ISBN supplied free by a platform generally has restrictions on where it can be used.

Also, KDP Expanded Distribution is not Kindle Unlimited. Expanded Distribution concerns eligible print books; Kindle Unlimited/KDP Select concerns ebook enrollment and exclusivity.

Five questions to ask before checking Expanded Distribution

1. Do I own the ISBN? Know whether you’re using your own ISBN or one provided by a publishing platform, and what that permits.
2. Might I want IngramSpark later? If bookstore and library distribution is a serious goal, compare the two approaches before enrolling anywhere.
3. What would I actually earn? Compare current royalties and print costs using your specific trim size, page count, list price, and sales territory.
4. Am I expecting bookstores to stock the book? Neither program guarantees that. Availability, discoverability, ordering terms, and actual demand are different things.
5. What happens if I change my mind? Ask about removing distribution, title transfers, ISBN records, and possible processing time before you need a quick change.

Would we check that box again?

Not automatically. We would first decide where we wanted a paperback distributed, compare the economics, and choose the setup that best fits that book. Expanded Distribution brought WhistlePig some sales, and we don’t want to dismiss those. But in our case, the later administrative delay made us wish we’d considered our longer-term plans before opting in.

If you’re publishing your first paperback, you don’t have to solve every distribution question in a day. A little research before checking a box may save you weeks of work later.

Our transfer story isn’t finished

We’re waiting for IngramSpark to complete the transfer and will update this article when we have a confirmed outcome. That’s part of running an independent publishing company: sometimes the most useful lessons arrive after the decision has already been made.
