I just recently stepped into my first auditing position. My next audit I am working on is the bank's ACH audit. I have been reading the ACH Rules and Guidelines book, but still have a question that you all may be able to help me with.
What kind of a sample of the ACH transactions should I be using? 50%, 75%, 100%, etc.? Like I said, this is the first one that I have done, and am not sure on some things, so any other tips you might have would be greatly appreciated. Thank you!
