Maybe we're looking at a difference between AE and BE here.

Etymology: Middle English, from gerund of accounten to account
1 a : the system of classifying, recording, and summarizing business and financial transactions in books of account and analyzing, verifying, and reporting the results b : the body of principles, conventions, and procedures underlying accounting -- distinguished from bookkeeping
2 a : practical application of accounting -- see COST ACCOUNTING, PUBLIC ACCOUNTING b : an instance of applying the principles, conventions, and procedures of accounting to the financial condition of an individual or individual organization
3 : the presenting or stating of accounts <the treasurer rendered his annual accounting>
4 : the process of devising and installing systems of accounts
As I said earlier, I believe as a practical matter "accounting" is used for both meanings in AE and "accountancy" only used in formal or legal contexts. My son-in-law is a Certified Public Accountant and I can ask him for the true information if anyone is that interested.
