Micro-Entries: What They Are—and What They’re Not

This brief course introduces Micro-Entries as defined by the Nacha Operating Rules and explains their proper formatting, compliance obligations, and appropriate use cases. Learners will explore how Micro-Entries support account validation—without confirming account ownership—and the importance of fraud detection and authorization requirements, especially for debit Entries. This self-paced session is designed to be completed in under 20 minutes.

Reversing Files and Entries

Avoid costly mistakes—know when you can reverse an ACH Entry! Not every error is eligible for a Reversal—and not every Reversal is a Reversing File. This quick session breaks down the five specific types of Erroneous Entries, explains why fraud-based payments don’t qualify, and shows how to stay compliant when a Reversing Entry is truly permitted. Clear, concise, and practical—perfect for Originators and ACH professionals who want to avoid unnecessary risk.
