What accounting software do CA firms use?

[Pracs]

All the Big4 use audit softwares PwC - Team Asset, Deloitte - AS/2, Ernst & Young - AWS & GAM. I am not sure about KPMG as I haven't worked for the firm. All of these have been developed internally or are designed specifically for these firms. The Audit softwares include Audit Plans, documentation, Excel spreadheets, Electronic archiving and other analysis tools.
