I created a course specifically for this topic a few years back, just before the Scrivener 3 update. It’s somewhat dated, especially since the compiling features have been significantly updated, but most of the tips are still applicable.
Anyway, one of the main reasons I decided to create this course was because I felt that no one should be stuck having to rely on another service after having spent their hard-earned money on Scrivener, which, IMHO, should be seen as an all-in-one writing tool. Why buy it at all if you’re not willing to put a little skin in the game and learn how to use it to its full potential. And thus, the course was born.
Granted, I recommend when people get started using Scrivener that they only use the features they need at the time and wait until they need other features to begin learning about them. If you’re not a read-the-manual-first type of person with a love for research and learning (guilty), then you’ll just get overwhelmed by the project and it will suck all the enjoyment Scrivener can provide.
Having said all that, I myself personally compile with Scrivener and don’t expect it to be a fully-functional formatting program (with drop-caps—yet, lol—and other “fancy” features), but it’s more than capable of producing professional-grade formatting. Most importantly—this just occurred to me—you don’t need all the bells and whistles in your formatting anyway if you truly want your focus to be on the writing itself. Worry about the writing, do the minimal amount of formatting you can be satisfied with…and get back to writing!
Otherwise, if you’re so inclined, you can more than throw money at the problem with other solutions out there. (Note, Draft2Digital offers free book formatting and ebook conversion that’s worth checking out. I haven’t tried it myself, but it looks easy and professional enough for me should I decide to give it a try.)
Bottom line: When I purchase a product, I prefer to know all there is about it before looking elsewhere. Time is money, and if it takes me way too many hours to solve a problem, I have two choices: throw money at it, or spend the time learning how to do it myself and acquire new skills in the process. Skills which often prove to be priceless.
