ACH Micro-Entries
The NACHA Micro-Entry Rule:
- Defines micro-entries as ACH credits less than $1 and any offsetting ACH debits, used for the purpose of verifying a receiver’s account.
- Standardizes the company entry description as ACCTVERIFY.
- Requires the company name to be easily recognizable to the Receiver.
When creating a new batch of ACH micro-entries, you can select the Micro Entries checkbox on the Batch Maintenance window to automatically populate ACCTVERIFY as the batch description and PPD as the standard entry class.

Once you add micro-entries to a batch, you cannot clear the Micro Entries checkbox to change the batch to accept items other than micro-entries.
On the Member/GL Item - New window, when you select a batch ID with the Micro Entries checkbox selected on the Batch Maintenance window, Portico displays a Micro-entries only indicator on Member/GL Item - New window and limits the Frequency drop-down list to Request and Same Day.

When you select Save, Portico verifies that the Amount field is less than $1.00 and the correct NACHA transaction code appears in the Back Office Transaction field and Receiving Transaction field. You can use the following transactions codes for a micro-entry:
- 22 - Credit to share draft/checking
- 27 - Debit to share draft/checking
- 28 - Prenote of debit to share draft/checking (Valid for Receiving Transaction field, frequency must be Request, and effective date must be 3 business days in the future.)
- 32 - Credit to shares/savings
- 37 - Debit to shares/savings
- 38 - Prenote of debit to shares/savings (Valid for Receiving Transaction field, frequency must be Request, and effective date must be 3 business days in the future.)
On the Member/GL Items window, Portico displays Y in the Micro Entry column to identify micro-entries in a batch.

To help you identify micro-entries on your ACH reports, the ACH Origination Report 173 and Automated Clearing House System Report 174 display Y in the MICRO column.
