Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
BookBaby
- Every stage beyond the base package, ISBN registration, expanded distribution, extra proof revisions and editing, is billed separately, so the advertised entry price is rarely the final cost.
- Unlike Draft2Digital or Kindle Direct Publishing, there is no free tier; authors pay upfront for services regardless of whether the book ever sells a copy.
- Revision rounds after the first proof are charged per round, which penalises authors who want to iterate on formatting.
- Editing is priced per word rather than as a flat fee, so a full manuscript edit can cost more than the entire publishing package.
- It packages services that KDP, Draft2Digital and IngramSpark offer for free or on a royalty-share basis, so cost-conscious authors comfortable with self-formatting pay for convenience they do not need.
Calibre
- The interface is dense and widely described as unintuitive, with a great deal exposed at once
- Conversion between formats is imperfect, and complex layouts degrade
- Cannot remove DRM, so purchased books from most stores will not convert without third-party plugins
- Heavy for someone who only wants to read rather than manage a library
