Should I use KDP or BookSpace?

Use KDP for Amazon discovery and BookSpace for direct-to-reader sales. KDP is a marketplace; BookSpace is your owned storefront with customer data and direct-sale economics.

Does BookSpace replace Amazon KDP?

Not usually. Most authors should keep KDP for readers who shop on Amazon and add BookSpace for traffic they generate themselves.

Which pays more per direct sale?

BookSpace usually pays more on direct sales because it charges no platform commission while print, shipping, and card costs still apply. KDP royalties are based on Amazon's royalty rate minus print cost.

KDP vs BookSpace: Use Amazon for Discovery, BookSpace for Readers You Already Earned

KDP is excellent at one thing: selling books inside Amazon. BookSpace is built for the other part of the author business: your storefront, your customer relationship, and the economics of direct demand.

Verdict

KDP is where Amazon shoppers buy. BookSpace is where your audience should buy.

The mistake is sending newsletter, event, and social traffic to Amazon by default. That traffic is already yours. A direct storefront lets you keep more margin and learn who bought.

When KDP wins

Discovery and reader habit

If someone starts on Amazon or strongly prefers Amazon checkout, KDP is the natural path. Do not fight that behavior.

When BookSpace wins

Owned demand

If the reader came from your work, your list, your talk, or your campaign, direct checkout protects the relationship and the margin.

Best stack

Use both deliberately

Keep KDP available. Make BookSpace the primary link in your owned channels, launch pages, QR codes, and author website.
