This books certainly contains some helpful information if you're going to start you own bookkeeping business, but 3 major things make me recommend you think twice before purchasing this book:
1. To say frankly, this books is about starting ANY professional service business, not just bookkeeping. It certainly refers to some accounting topics - i.e. choosing accounting software etc., but essentially it gives you no idea about how to build competitive advantage of your bookkeeping business and doesn't tell you any ins and outs of this particular business type
2. This books is poorly edited - it has two authors and it looks like these authors wrote different part of the books and nobody took time to make sure that the book is cohesive and doesn't say the same ideas twice. Pictures in this book just magnify the impression of a poor editor work - they are absolutely not stylish and resemble the standard picture set of MS Word in 1990s. This is certainly not to say that poor editing will preclude you from understanding what this book is about, but I expected much more from the item priced at $40.
3. Talking about "Tax preparation" part of this book, the whole content of this chapter can be put into one sentence "At some point of time in developing your bookkeeping business, you might find it interesting to expand your services into tax preparation field". Well, this looks too simplistic to me - taxation is one of the most complicated areas of finance and just to say that sometimes you will wake up and decide to get into this field and next morning you will be there is just odd.
To put is short, if this book cost $15 and were titled "A couple of nice ideas about getting into the world of services business", I would certainly give it 5 star. But a combination of this book's actual name and its $40 cost only earns a 3 star rating.
