The global ebook market surpassed $18 billion in 2024 and continues to grow, with Latin America alone generating 42.3 million euros in digital book revenue. For publishers, the question is no longer whether to sell ebooks—it’s which platform to build on.
Choosing the wrong ebook platform costs more than money. It costs time spent migrating catalogs, readers lost to clunky interfaces, and revenue surrendered to unfavorable revenue-share models. This guide breaks down the criteria that matter and helps you make a decision you won’t need to revisit in 18 months.
What an Ebook Platform Actually Needs to Do
Before comparing vendors, define what “platform” means for your publishing operation. At minimum, a production-ready ebook platform must handle six core functions:
- Catalog management – Ingesting, organizing, and updating metadata for hundreds or thousands of titles
- Digital Rights Management (DRM) – Protecting content from unauthorized distribution
- Payment processing – Handling transactions, taxes, and multi-currency support
- Reading experience – Delivering content to readers on web, iOS, Android, and desktop
- Analytics – Tracking sales, reader behavior, and catalog performance
- Distribution control – Deciding where and how your content reaches readers
If a platform doesn’t cover all six, you’ll end up stitching together third-party tools—and managing the integration overhead that comes with them.
Catalog Management: The Foundation
A platform’s catalog system determines how much operational friction you’ll deal with daily. Evaluate these specifics:
- Bulk import capabilities: Can you upload EPUB, PDF, and audiobook files in batch? Does it accept ONIX feeds or require manual entry?
- Metadata handling: Does it support multi-language metadata, custom taxonomies, and BISAC/BIC subject codes?
- Multi-format support: Modern catalogs include EPUBs, fixed-layout PDFs, and audiobooks. A platform locked to one format limits your product strategy.
- Update workflow: When you need to fix a typo in a published ebook or update cover art, how many steps does it take?
The best catalog systems feel invisible. They let your editorial and operations teams focus on content, not data entry.
DRM: Protection Without Friction
DRM is a balancing act. Too aggressive, and you alienate readers with device restrictions and cumbersome activation steps. Too lax, and your content circulates freely on piracy sites.
Look for platforms that offer:
- Transparent DRM that works silently in the background without requiring readers to install third-party software
- Flexible policies that let you set different DRM levels per title or collection
- Offline reading support so DRM doesn’t break the experience when readers are on a plane or subway
Avoid platforms that force a single DRM approach across your entire catalog. A university textbook and a romance novel have very different protection needs.
Payment Processing and Revenue
This is where platform choice has the most direct impact on your bottom line. There are two models:
Marketplace Distribution
Selling through Amazon Kindle, Apple Books, Google Play, or Kobo means accessing massive audiences. But it comes at a cost: publishers typically retain 35% to 70% of the sale price, depending on the retailer and price tier. You also lose control over customer data, pricing flexibility, and the ability to run custom promotions.
Direct-to-Consumer (D2C)
Selling through your own branded platform—your website, your app—lets you keep 70% to 90% of every sale. You own the customer relationship, control pricing and bundling, and collect first-party data for marketing.
The math is straightforward. On a $15 ebook:
| Channel | Publisher Revenue Share | Revenue per Sale |
|---|---|---|
| Major marketplace (70% tier) | 70% | $10.50 |
| Major marketplace (35% tier) | 35% | $5.25 |
| D2C platform | 85–90% | $12.75–$13.50 |
Over thousands of transactions, the difference compounds significantly. D2C doesn’t mean abandoning marketplaces—it means not depending on them entirely.
Analytics: Beyond Sales Reports
Basic sales dashboards are table stakes. The platforms worth investing in provide:
- Reader engagement metrics: How far do readers get? Which titles have high completion rates? Where do readers drop off?
- Catalog performance: Which categories, authors, or price points drive the most revenue?
- Subscriber behavior: For subscription models, which titles retain subscribers vs. which ones attract trial users who churn?
- Revenue analytics: Real-time reporting on sales, refunds, and revenue by channel, country, or time period
Data-driven publishers outperform those operating on intuition. Your platform should make data accessible, not locked behind export-only CSV files.
White-Label vs. Marketplace: The Strategic Choice
This is the decision that shapes everything else. Here’s how the two models compare across key dimensions:
| Criteria | Marketplace | White-Label Platform |
|---|---|---|
| Brand presence | Your titles appear alongside millions of others | Your brand, your storefront, your identity |
| Revenue share | 35–70% | 70–90% |
| Customer data | Owned by the marketplace | You own all reader data |
| Pricing control | Subject to platform rules and price-matching | Full control over pricing, bundles, and promotions |
| Discovery | Built-in audience, algorithm-driven | You drive traffic through your own marketing |
| Customization | Minimal—you follow their template | Full control over UX, features, and layout |
| Dependency risk | Policy changes can impact your business overnight | You control the platform and the terms |
For publishers with an established audience or institutional buyers, white-label platforms offer substantially better economics. Marketplaces remain valuable as discovery channels, but building your business on someone else’s platform means building on rented land.
Key Questions to Ask Every Vendor
When evaluating an ebook platform for publishers, bring this checklist to every demo or sales call:
- What formats do you support? EPUB, PDF, audiobooks, and fixed-layout should all be covered.
- How does DRM work? Is it transparent to the reader? Can you configure it per title?
- What’s the revenue model? Flat fee, percentage of sales, or hybrid? Are there hidden transaction fees?
- Do I own my customer data? Can you export reader lists, purchase histories, and engagement data?
- What reading apps are available? Web reader only, or native iOS/Android/desktop apps?
- How do you handle multi-tenancy? If you manage multiple imprints or brands, can each have its own storefront?
- What’s the integration story? APIs, webhooks, ONIX support, and third-party payment processor compatibility.
- What does migration look like? If you’re moving from another platform, how is catalog and subscriber data transferred?
Making the Decision
The right ebook platform aligns with three things: your current catalog size, your growth trajectory, and your willingness to own the customer relationship.
If you’re a publisher with 50+ titles and an existing audience—through email lists, institutional partnerships, or a recognized brand—a white-label D2C platform will almost certainly deliver better long-term economics than relying solely on marketplace distribution.
If you’re just starting out with a small catalog and no audience, marketplaces offer low-friction entry while you build. But plan your migration early. The longer you wait, the more customer relationships you build on platforms that won’t let you take that data with you.
The best strategy for most publishers is a hybrid approach: use marketplaces for discovery and reach, but funnel your most engaged readers toward your own branded platform where you control the experience, own the data, and keep the lion’s share of revenue.
Whichever path you choose, evaluate platforms on the six criteria above—and don’t settle for one that only solves half the problem.
