IngramSpark helps retailers find and order your book. Books.by helps readers buy from you. Those are different jobs, and the right answer is often to use both for different traffic.
Use IngramSpark when wholesale availability is the goal. Use Books.by when the sale comes from your own marketing and you want customer data, margin, and checkout control.
| Decision point | IngramSpark | Books.by |
|---|---|---|
| Primary role | Wholesale distribution to trade channels | Direct-to-reader storefront and checkout |
| Customer relationship | Retailer/customer stays outside your account | Author keeps customer/order data |
| Royalty model | List price minus wholesale discount and print cost | List price minus print, shipping, and card costs with no Books.by platform commission |
| Best for | Bookstores, libraries, trade catalog availability | Newsletter, website, QR, events, creator-led sales |
| Files | Print-ready interior and cover PDFs | Print-ready PDFs and Books.by setup tools |
A bookstore sale has more intermediaries. That can be worth it for reach, but it is not the same as a direct sale.
Bookstores, libraries, and institutional buyers often need a wholesale catalog path. That is what IngramSpark is built for.
Email, speaking, social, podcast, classroom, and ad traffic should not automatically pay wholesale economics.
Put the book where trade buyers can order it, then make your direct storefront the link you actively promote.
