Firebrand worked with the largest ebook retailers to create the most robust EPUB test suite available. Files are verified against the actual requirements of Amazon, Apple, B&N, Kobo, Google, and NetGalley, using their own testing tools or using algorithms we created based on their requirements. Publishers receive comprehensive reports detailing whether or not the file will be accepted by these partners and explaining anything that needs to be fixed.

Frequently Asked Questions about FlightDeck

Why do our ebook files pass standard EPUBCheck but still get rejected by retailers like Apple or Amazon?
Basic validation tools only check your files against general EPUB standards, not the specific ingestion rules of individual retail platforms. FlightDeck goes far beyond basic EPUBCheck by running your files against the actual, strict requirements of major retailers like Amazon, Apple, Barnes & Noble, and Google. This ensures your files aren't just technically valid, but guaranteed to be accepted by the specific platforms where you sell.
How can our team fix complex coding errors without needing a dedicated developer?
Cryptic error messages from standard validation tools can stall your production pipeline. FlightDeck interprets and explains standard errors and warnings in clear, human-readable terms, providing examples and tips for hard-to-understand code issues. Furthermore, our built-in metadata editor empowers your non-technical staff to make rapid updates to the EPUB file without requiring any coding expertise.
How can we efficiently audit our EPUB backlist for modern accessibility standards without overwhelming our QA team?
How do we prevent “last mile” retailer rejections for hidden issues like blurry cover images or illegal formatting?
A rejected file at the point of upload means costly distribution delays and lost revenue. FlightDeck proactively flags platform-specific rejections before you ever hit “Submit.” By running deep file statistics—including checks on image dimensions, embedded fonts, and external links—FlightDeck catches the hidden, “invisible” errors that cause Amazon KDP or Apple Books to reject a file, saving your team from endless fix-and-upload loops.
