After the book has been approved by our internal review team, we send the book to stores immediately.
However, each store has additional review processes, so the publishing date will vary.
Store don’t automatically accept books, as they have to check for copyright and quality issues, but we do everything in our power to speed up publishing times.
In the case of Apple Books (iBooks), we are one of their trusted partners, which means that it usually takes only a few hours to 3 business days to get an ebook published. In other big stores, such as Amazon, Kobo, Barnes and Noble, and Google, it usually takes 3-5 business days to get a book onto shelves.
Typically, it doesn't take longer than 14-28 business days for a book to be accepted in any of the stores, but certain public holidays (such as Christmas and Chinese New Year) and occasional maintenance may influence the speed of publishing by the stores.
We suggest that if you have a book with a strict publication date, you upload it at least two weeks in advance. In this case, your book will be automatically set for pre-sale in the stores where this function is available.
