IngramSpark vs KDP (also searched as Amazon KDP vs IngramSpark) is a channel choice, not a contest. KDP is Amazon’s store. IngramSpark is a print-on-demand and wholesale catalog so other retailers can order a paperback. Most debut print plans that want both places use both rails.
IngramSpark vs KDP
| KDP | IngramSpark | |
|---|---|---|
| What it is | Amazon’s upload dashboard for Kindle and Amazon print | POD plus a wholesale catalog |
| Who can buy | Amazon shoppers | Retailers and libraries that order through wholesale. They still choose whether to stock it. |
| Account | kdp.amazon.com, yours | An Ingram account, yours |
| Files | KDP interior and cover templates | Ingram’s own specs and cover calculator |
| Print royalty shape | On Amazon.com, 50% or 60% of list price minus printing cost. See KDP royalties. | Wholesale discount plus print cost. Read Ingram’s current schedule. Do not copy the KDP percentage across. |
| Setup fees | Usually none to upload | Confirm title and revision fees on Ingram’s site. They change. |
| Proof | KDP preview, then a printed proof if you order one | Ingram’s file review, then a printed proof if you order one |
When KDP alone is enough
Choose KDP alone when Amazon is the whole plan and the interior and cover are already built to KDP’s spec. You do not need a second catalog to sell a Kindle book.
When to add IngramSpark
Add an Ingram-class file when you want a bookstore or library to be able to order the paperback. That is orderability, not a promise the store will put it on a shelf. Doing both yourself means two covers (spine width is recalculated), two interiors if the templates differ, and two proof cycles.
What a package coordinates, and what it does not
AuthorShelf packages include global retail and POD setup so you are not building two dashboards from a blank page. You keep the accounts and 100% of net royalties. We do not take a cut of book sales. We also do not promise shelf space or an Amazon rank.
