As the long-time #1 best-seller, Garrison has helped guide close to 3 million students through managerial accounting since it was first published. It identifies the three functions managers must perform within their organizations€”plan operations, control activities, and make decisions€”and explains what accounting information is necessary for these functions, how to collect it, and how to interpret it. Garrison€™s Managerial Accounting is known for its relevance, accuracy, and clarity. It is also unique in that the authors write the most important supplements that accompany the book: solutions manual, test bank, instructor€™s manual, and study guide €“ making them both of high quality and extremely consistent with the textbook.
