I have a big issue with my Managerial Accounting assignments. Thy asked me to study and evaluate companies' Accounting systems and how they applied it to their work. But the problem is that when I ever search on the company's website or just google for the using accounting systems in a particular company, I can't find any good resource of information. So, I'm wondering if there is a reliable resource for graduate students to get the direct information about the how companiesuse a certain type of accounting system.

Hope to hearsomething as soon as possible.
