The e-book cover should have a design, the title and the author.
The title of the book is "Guide to Buying a Successful Business: Easy to Follow Steps for Effective Financial Due Diligence"
The author of the book is "David Sack, CPA, CFA, ASA, ABV, CBA, CFF"
You can use your own judgment in the font and format of the title and subtitle.
The design should give the impression that the book is easy to follow and not complicated. The main idea of the book is that it takes a very complicated process and boils it down into easy to follow steps.
