Heads up: This is a plain-language summary, not official policy, and rules change often. Always confirm the current requirements with the official source linked in each section. BookZeta does not publish on your behalf and can't guarantee any marketplace will accept your book.

Amazon isn't the only place to sell a book, and many authors publish to several stores to reach more readers. Each platform has its own audience, file specs, metadata rules and royalty terms, so it's worth knowing your options before you commit. Broadly, you can go to each store directly or use an aggregator that pushes your book to many stores from one dashboard.

Direct stores

• Apple Books for Authors — eBooks across the Apple ecosystem (iPhone, iPad, Mac), reaching readers who buy through Apple.
• Kobo Writing Life — strong global eBook and audiobook reach, especially outside the U.S.
• Google Play Books Partner Center — eBooks for Android and Google users worldwide.
• IngramSpark — wide print distribution into bookstores and libraries, which reach places Amazon's print program may not.

Aggregators

• Draft2Digital — distributes your book to many stores at once from a single upload, which can save a lot of manual work.

Direct vs. aggregator — how to choose

There's a genuine trade-off here:

• Going direct to each store often means better royalty rates and access to each store's own promotional tools and dashboards — but more accounts to manage and more uploads to keep in sync.
• Using an aggregator is simpler (one upload, one place to update) and reaches many stores you might not set up individually — but the aggregator typically takes a cut, and you're a step removed from each store's controls.

Many authors mix the two: direct on the biggest stores, aggregator for the long tail.

A few things to keep in mind

• Watch for overlap. Some aggregators distribute to stores you might also publish to directly — don't accidentally list the same book twice on the same store through two channels.
• Specs differ. A cover or EPUB that passed on one store may need tweaks for another; check each platform's current requirements.
• Identifiers matter. Distributing widely is a common reason to use your own ISBN rather than a store-assigned one — see ISBNs.
• Disclosure still applies. Each store may have its own AI-content questions — see AI content disclosure.

Your BookZeta EPUB and print PDF can be uploaded to most of these platforms, so the same exported files often work across several stores with only minor adjustments. Start with one or two, get comfortable with the process, then expand.
