Are Annual ACH Audits required at banks which are outsourcing their computer processing? If audits are required, where can I find the audit requirements?

Yes, if you are an originating bank or receiving bank, you have to conduct the self-audit according to the rules. The requirements are found in Section 8 of the ACH Rules book and/or you can contact your regional ACH Association for classes and other ACH audit-related publications.

I have an excellant tool that I use. It's called the ACH Workbook. It is produced by Mid-America Payment Exchange. It is updated annually and costs $75. Try this website-www.mpx.org
