Walter Grant has collated all information you would wish to refer if you are starting your business. It is organized well too. If that is not enough, he also has checklists for each topic. The book can be helpful to beginners contemplating their business and have not yet read many management books.
However, if you are attempting a side hustle or a small business, it might not be for you. It also is not for someone who has been doing business for some time. Besides that, the 7-step process mentioned in the subtitle is rather unclear.
Note: BookSirens gave me a free copy of this book in exchange for an honest review.
