Independent KDP publishing services
KDP is free to use, and it will publish almost anything. Whether the book sells is decided before the upload: the cover at thumbnail size, the first pages in Look Inside, the categories and the description. We do all of that, then set the book up on KDP and IngramSpark in your own accounts.
Tell us about the book. A specialist replies within one business day with the setup it needs and a clear price. Nothing is charged until you approve it.
The short answer
Columbia Publication is an independent KDP publishing service, not affiliated with Amazon. For a flat fee from $1,499 we prepare your book for Amazon KDP, with a thumbnail-tested cover, print and Kindle formatting, ISBNs, researched categories and keywords, and a written description, and set it up on IngramSpark for bookstores. Your KDP account stays in your name, and most books are live in 4 to 9 weeks.

Is this you?
KDP accepts files. It does not make them sell.
A cover that cannot be read as a thumbnail loses the click. A Word upload shows uneven pages in Look Inside. A description written as a summary gives no reason to buy, and the wrong categories hide the book from the readers looking for it. KDP offers no help with any of it.
We handle every one of those decisions before upload, preflight the files against KDP’s specs, and submit them from your own account. If KDP rejects a file for a specification error on our side, we fix it at no charge.
Royalties
KDP pays 70% on ebooks priced $2.99 to $12.99 (35% outside that band) and 60% of list minus print cost on paperbacks at $9.99 or more.
| Format and price | KDP royalty | You earn about |
|---|---|---|
| Ebook at $4.99 | 70%, less a small delivery fee | $3.49 |
| Ebook at $9.99 | 70%, less a small delivery fee | $6.99 |
| Paperback at $14.99 (250 pages) | 60% minus $4.00 print cost | $4.99 |
| Paperback at $17.99 (250 pages) | 60% minus $4.00 print cost | $6.79 |
Ebook figures before the delivery fee, which depends on file size. Columbia Publication takes no share of any royalty.
Before the upload
| What decides it | What KDP gives you | What we do |
|---|---|---|
| Cover | An upload slot | Designed for your genre and tested at thumbnail size |
| Interior | Automated conversion | Print PDF and Kindle file typeset and preflighted |
| Categories | A picker | Researched against the categories where your book can rank |
| Keywords | Seven empty boxes | All seven filled with phrases readers actually search |
| Description | A text box | Written as sales copy, not a summary |
| ISBN | A free Amazon-only ISBN | ISBNs from our Bowker block, or your own, so bookstores can order |
Decisions
Your genre decides it. KDP Select asks for 90 days of ebook exclusivity on Amazon in exchange for Kindle Unlimited and promotional tools.
Genre fiction with heavy Kindle Unlimited readership: romance, thriller and fantasy.
Non-fiction, business and literary fiction, sold on Apple Books, Kobo and through libraries as well.
Your specialist recommends one for your book, and print editions are unaffected either way.

Questions
No. Columbia Publication is an independent publishing service. KDP is free to use, and your KDP account stays in your name.
KDP itself is free. The cost is professional production before upload: editing, cover, formatting and setup. Columbia Publication packages start from $1,499 as one flat fee.
70% on ebooks priced $2.99 to $12.99, less a small delivery fee, and 35% outside that band. Paperbacks at $9.99 or more earn 60% of list minus print cost, so a 250-page paperback at $14.99 earns about $4.99.
Yes. KDP takes a non-exclusive distribution license only, and Columbia Publication takes no rights and no share of royalties.
KDP sells on Amazon. IngramSpark makes your book orderable by bookstores, libraries and wholesalers. Every package sets up both.
Production typically takes 4 to 9 weeks. Once files are approved, ebooks go live within about 72 hours and print soon after.
Genre fiction with strong Kindle Unlimited readership often benefits. Non-fiction and literary titles usually do better wide. Your specialist recommends one for your book.
In full upfront, once you approve the quote. KDP itself never charges you, and we take nothing from your Amazon royalties.
