Today - again - I was scratching my head over an accounting mess, for which the owner had paid a bookkeeper many dollars over many years. How did it happen? If you don't know the basics, you are a sitting duck, my friend.
You know accountants do it on purpose. They use weird words to make you think that they are smarter than you are. To keep you in the dark. Or, the less nasty ones just don't know better.
