ACX (Audiobook Creation Exchange) and Findaway Voices are the two dominant platforms for self-published audiobooks. They're not direct competitors — they have very different business models and serve different author goals. The choice between them isn't about which is "better"; it's about which matches your distribution strategy.
The quick comparison
| Factor | ACX (Exclusive) | Findaway Voices |
|---|---|---|
| Royalty rate | 40% | 80% |
| Distribution | Audible, Amazon, iTunes only | 40+ platforms (Spotify, Kobo, libraries, etc.) |
| Exclusivity required? | Yes (7 years for 40% rate) | No — non-exclusive |
| Narrator marketplace | Yes — large pool | Yes — growing pool |
| Royalty share option | Yes (50/50 with narrator) | Limited |
| Library distribution | No | Yes (OverDrive, hoopla, etc.) |
| Spotify distribution | No | Yes |
| Non-exclusive ACX rate | 25% (much lower) | N/A |
ACX in depth
ACX is Amazon's audiobook platform, distributing to Audible, Amazon.com, and iTunes. Audible is by far the largest single audiobook retailer — roughly 40–45% of the US audiobook market. For many self-published authors, Audible alone accounts for 70–80% of their audiobook revenue.
The exclusive ACX deal (40% royalties) locks you in for 7 years. That's a long time to be unable to respond to market changes or new platforms. But for genres where Audible dominates (science fiction, fantasy, thriller, romance), exclusivity may cost you very little in real missed revenue — listeners in those genres are overwhelmingly Audible subscribers.
ACX non-exclusive (25% royalties) is a worse deal in almost every scenario. You'd need to earn 60% more revenue from other platforms to make up for the 15-point royalty cut. For most authors, especially in the early stages of their audiobook catalog, the math doesn't work out.
Who ACX exclusivity makes sense for
- Authors in genres with predominantly Audible audiences (SFF, thriller, romance)
- Authors using ACX's royalty share program (narrator works free for 50% of royalties — only available under exclusive terms)
- Authors who want the simplest possible distribution setup with no ongoing management
Findaway Voices in depth
Findaway Voices (now owned by Spotify, operating as Spotify for Audiobooks' author platform) distributes to 40+ platforms: Spotify, Kobo, Libro.fm, Google Play, Apple Books, Chirp, OverDrive (libraries), hoopla, and many more. It pays 80% royalties and doesn't require exclusivity — which means you can publish through Findaway and also publish through ACX's non-exclusive option.
The practical challenge: while Findaway's reach is broad, many of these platforms have small audiobook markets compared to Audible. Spotify's audiobook presence is growing but still modest for indie authors. Library distribution through OverDrive is meaningful but pays per checkout rather than per purchase.
Findaway's 80% royalty rate is structurally excellent — but 80% of a smaller market may be less than 40% of Audible's market. The math depends entirely on your audience.
Who Findaway makes sense for
- Authors with an audience that skews toward non-Audible platforms (Kobo readers, library borrowers, Spotify listeners)
- Authors who prioritize retaining flexibility over maximizing the largest single platform
- Authors publishing in non-English languages where Audible's dominance is less pronounced
- Authors who have already published elsewhere and want wide distribution without exclusivity constraints
The rights question
When you publish through ACX exclusive, Amazon doesn't own your audiobook — you retain copyright. What you've granted is an exclusive distribution license for 7 years. At the end of 7 years, you can choose not to renew and move the title elsewhere.
Findaway's non-exclusive arrangement means you can add, remove, or change distribution channels at any time. This is a meaningful long-term advantage if the audiobook market continues to diversify.
The decision framework
If you're writing commercial genre fiction (fantasy, romance, thriller, sci-fi) for an English-speaking audience and you're just starting your audiobook catalog: ACX exclusive is usually the right call. Simplicity, higher royalties on your biggest market, and access to the royalty share program if budget is a constraint.
If you're writing non-fiction, literary fiction, or have an existing audience outside Audible; if you care about library distribution; or if your ebook distribution is already wide and you want audio to follow the same model: Findaway Voices gives you flexibility that ACX exclusive doesn't.
