This is an introductory book on ultra-practical accounting based on the author's actual experience that a small company that continued to lose money despite sales growth recovered to a V-shaped recovery and turned into a surplus one day after being taught the concept of "management accounting," especially "marginal profit," by an excellent tax accountant. The author has learned lessons such as "fixed cost is an uncaring expense," "variable cost is a expense," and "to have a delicate macho constitution to turn into a surplus." It is easy to understand because knowledge of difficult accounting is almost unnecessary.
