Explanation:

Managerial accounting information can also provide a basis for assessing how and when your business will grow. All sales, expenses and cash related information are included in these determinations, which depend on your management team's ability to understand and process the numbers available to make a successful call. Just because your business needs more money does not mean investing in a new product or new market. You can't get enough capital to do justice to this move, or you still can't understand what your customers want or need. You need to collect your data across different segments of your business to provide the key information you need to identify to use management accounting data for growth planning. You need to explore potential costs and markets to better understand how and when your new initiatives can pay for themselves.  Of course, there is no way to accurately estimate the sale of a new product in a new market. However, if you understand your company's past performance and current spending trends, you can use this information to provide informed forecasts for future efforts.
