The days of publishing gatekeepers, perched high in their New York City skyscrapers, are over. New technologies have made it easier than ever for first-time authors to realize their dreams. Sure, the Big Five Publishers (Penguin Random House, HarperCollins, Simon & Schuster, Hachette, and Macmillan) still control Around 70%–75% of traditionally published print book sales in the U.S. But self-publishing has exploded in popularity in the last 5-10 years.
The Self-Publishing Revolution
According to Bowker (U.S. ISBN agency): In 2024, there were 2.3 million self-published titles with ISBNs—a 216% increase over 2020. (This number doesn’t even include titles with freeISBNs provided by Amazon.) One thing is clear: The self-publishing services industry is growing rapidly, and shows no signs of slowing down.
Self-publishing has given authors the opportunity to share their work with readers across the globe. This idea was an impossible dream up until the advent of POD (Print-On- Demand) about a decade ago. Digital presses make it possible to print books only when ordered. This eliminates the need to print thousands of copies in advance or find warehouse space to store them.
At the heart of this revolution are two game-changing platforms—Amazon KDP and IngramSpark. Together, these two giants have opened the gates of publishing to independent authors everywhere.
Navigating the Publishing Landscape: How Sprig Publishing Solutions Can Help
While the printing process has been streamlined, and KDP and IngramSpark make it easier than ever, the publishing process can still be a confusing, time-consuming, and overwhelming challenge for the average author. New authors face dozens of decisions—where to publish, which tools to use, what formats to choose, how to price, and so on. At Sprig Publishing Solutions, we simplify the process by walking authors through the steps, offering clear guidance and handling all the technical parts—from design to distribution.
What Are Amazon KDP and IngramSpark Exactly?
Authors should choose the platform that best aligns with their specific publishing goals, whether that means reaching brick-and-mortar bookstores, maximizing royalties, or getting their books into reader’s hands as quickly as possible. Each platform has its strengths and weaknesses. Understanding what each platform offers—and how they can complement each other—can make a big difference in your book’s success.
Amazon KDP: The Giant of Online Sales
Amazon KDP (Kindle Direct Publishing) is Amazon’s self-publishing platform. It was originally launched in 2007, alongside the first Kindle e-reader. The platform was designed to give authors a quick and easy way to publish their books digitally (and later in print), without going through traditional publishers. Today, it’s the most widely used self-publishing platform in the world, allowing authors to publish and sell their books directly on Amazon in multiple countries. Amazon KDP allows authors to publish their books in multiple formats, including e-books, paperbacks, and hardcovers. With tools for setting pricing, choosing distribution options, and tracking royalties, KDP has become the go-to platform for indie authors looking for speed, visibility, and control.
IngramSpark: Your Gateway to Broader Distribution
The IngramSpark self-publishing platform was launched in 2013 by Ingram Content Group, one of the largest book distributors in the world. The platform was created to give independent authors and small publishers access to the same print and distribution networks as large traditional publishers.
Unlike Amazon KDP (where books are only sold on Amazon.com), IngramSpark focuses on a wide range of outlets—including bookstores, libraries, academic institutions, and online retailers like Barnes & Noble. It supports paperback, hardcover, and e-book formats, with more customization options than KDP. IngramSpark does not charge for initial uploads (setup fees) for new print or ebook titles. However, a $25 revision fee applies to each revised file after your book has been uploaded for 60-days.
Can I Use Both?
Yes, using both the KDP (Kindle Direct Publishing) and IngramSpark platforms makes a lot of sense for many authors. Here are a few reasons why:
Leveraging Amazon’s Reach
Amazon KDP is owned by Amazon, and therefore offers global visibility and convenience for selling directly to Amazon customers. It’s fast, free to use, and gives authors access to Amazon’s global customer base. You’ll also typically earn higher royalty sales compared to Amazon sales made through IngramSpark.
Unlocking Wider Distribution
IngramSpark distributes to bookstores, libraries, schools, and other non-Amazon retailers. It’s ideal for authors who want their book available beyond Amazon, especially in brick-and-mortar bookstores, or through wholesalers like Baker & Taylor.
Amazon KDP: Advantages and Disadvantages
Pros:
- Free to use
- Massive reach on Amazon
- Fast upload and changes
- Royalty options explained (e.g., 60% of list price minus printing)
Cons:
- Limited reach outside Amazon
- Less bookstore-friendly
- Paper quality limitations (if relevant to your audience)
IngramSpark: Advantages and Disadvantages
Pros:
- Wide global distribution (bookstores, libraries, B&N, etc.)
- Better chance of bookstore stocking (especially if you use your own ISBN)
- More print options (better quality paper)
Cons:
- Upload fees (a $25 revision fee applies to each revised file after your book has been uploaded for 60-days)
- More complex dashboard
- Slower update process
