Amazon KDP and IngramSpark are two of the most common platforms for independent authors. They are not direct competitors so much as tools for different jobs.
Potter Publishers sets up books on both Amazon KDP and IngramSpark, always in accounts that belong to the author. Here is how the two platforms compare, and how we help authors decide. For recent platform updates, see Amazon KDP changes in 2026.
Amazon KDP
KDP publishes ebooks and print books for sale on Amazon. Setup is straightforward, and its programmes can help with visibility on Amazon. If most of your readers buy on Amazon, KDP is usually essential.
IngramSpark
IngramSpark makes print books available to order through a large distribution network, so bookstores and libraries can order your title. It also supports formats such as hardcover with dust jacket. Its settings, including wholesale discount and returns, affect whether stores are willing to order your book and what you earn per copy.
Using both
Many authors use KDP for Amazon and IngramSpark for wider print distribution. If you do, plan your ISBNs and settings carefully so the editions do not conflict, and check each platform's current terms.
How to decide
- Selling mainly online, especially on Amazon: start with KDP.
- Want bookstores and libraries to be able to order your book: add IngramSpark.
- Publishing a hardcover: check which platform supports the format you want.
Comparing the two on what matters
- Where your book is sold. KDP focuses on Amazon's own stores. IngramSpark focuses on making print books available to order across its distribution network.
- Formats. Both handle paperbacks and ebooks; check each platform's current options for hardcovers and special formats.
- Setup. KDP is generally simpler for first-time authors. IngramSpark asks you to make more decisions about distribution.
- Control over distribution settings. IngramSpark lets you set wholesale discount and returns, which influence bookstore interest and your earnings.
Understanding wholesale discount and returns
Bookstores buy at a discount from the list price and generally expect to be able to return unsold copies. On IngramSpark you choose the discount and whether returns are allowed. A higher discount and returns make your book more attractive to stores but reduce what you earn per copy and can create costs if copies come back. Many authors aiming mainly at online sales choose differently from those aiming at bookstores.
Ebook considerations
Ebooks raise a separate choice: publishing exclusively through one retailer's programme, or distributing widely across many retailers. Exclusive programmes can offer promotional benefits; going wide reaches readers on other stores and in libraries. Check the current rules of any programme before you enrol, since exclusivity commitments can limit where you sell.
Avoiding conflicts when using both
If you publish the same print edition through both platforms, plan the setup carefully: decide which platform handles which channels, use your own ISBNs consistently, and match the trim size and files. Check each platform's current guidance on using both, as policies can change.
Which should you start with?
If your readers mostly buy online and you want the simplest start, KDP is a natural first step. If bookstores, libraries or events matter to you, or you want a hardcover with a dust jacket, IngramSpark is worth adding. Many authors begin with one and add the other once the book is established.
Print quality and proofs
Whichever platform you choose, order a printed proof before you approve your book for sale. A proof lets you check the cover colours, the spine alignment, the paper, margins and overall finish in person. Print quality can vary between formats and options, so check every format you plan to sell, and check again after significant changes to your files.
File requirements
Both platforms have specific file requirements for interiors and covers, including trim size, bleed, image resolution and how fonts are embedded. Requirements can differ between platforms, so a file that is accepted by one may need adjusting for the other. Working from your platform's current templates and specifications avoids rejected uploads and delays.
Pricing your print book
Print cost depends on page count, trim size, ink and paper choices, and the format. When you set your list price, consider the print cost, the retailer's or distributor's share, any wholesale discount, and what readers expect to pay for similar books in your genre. Each platform provides tools to calculate what you will earn at a given price.
Managing your books over time
Publishing is not a one-time setup. You may want to update your description, adjust prices, refresh the cover or upload corrected files. Keep your account details, ISBN records and final files organised so updates are straightforward, and make sure the accounts are in your name, so you always stay in control of your books.
Key takeaways
- KDP is built around Amazon; IngramSpark makes print books available to order more widely.
- IngramSpark's discount and returns settings affect bookstore interest and your earnings.
- Many authors use both, with careful planning of ISBNs and files.
- Always order and check a printed proof before release.
- Keep the accounts in your own name so you stay in control.
There is no single right platform for every author. Start from where your readers buy books and which formats matter to you, then choose the platform, or combination, that fits those goals.

Questions and next steps
Will IngramSpark put my book on bookstore shelves? It makes the book available to order; stocking decisions belong to each store.
Do I keep my royalties? Yes, when the accounts are in your name.
Do I need my own ISBN for these platforms? You can often use a free platform identifier, but owning your ISBNs keeps you as publisher of record and makes using both platforms simpler.
Can I change my settings later? Many settings, such as price, can be updated after publication. Check each platform's rules for changes to files and distribution.
Not sure which platform suits your book? Potter Publishers can recommend a setup and handle it for you. Ask our publishing team.
