Use ACH Manager for Account Opening

Prev Next

Your institution can use the ACH Manager for Account Opening (AO) in Narmi Command to view and manage your Narmi AO ACH Service transactions, including approving or rejecting ACH transactions in manual review and manually processing ACH transactions.

Note: For rejected transactions, your institution is responsible for reversing the transaction and removing any holds from the core. Narmi cannot reverse transactions. Go to Handling Manual Core Reversals for Rejected Funding Transactions to learn more.

Review AO ACH Transactions

If there are transactions in the Review tab, you’ll need to manually approve or reject them. Select one or more boxes next to the transaction(s) and select Approve or Reject.

Review section showing applicant details and options to approve or reject application.

A dialog appears asking you to provide an optional reason for the approval or rejection. If more than one transaction was selected, a banner indicates how many transactions will be approved or rejected. Select Submit.

Warning message indicating rejection of three transactions with additional information field.

Approved transactions automatically move to the Pending tab, and the account will be opened on the core. Rejected transactions move to the Rejected tab, and the application moves to “Funding Failed” status. If you reject the transaction, the applicant receives either one of two notifications, depending on the maximum number of funding attempts allowed per application set by your institution:

  • If the user has funding attempts remaining, then they would be sent an email (automatically) asking them to re-fill out their transaction information and resubmit. This would create a new transaction.

  • If the user does NOT have funding attempts remaining, they receive an email notification of the rejection.

The number of attempts can be set in Narmi Command under Institution Settings > Maximum Funding Attempts Per Application. The default is 20 attempts. Each funding attempt gets added to a single total, even if the applicant switches between ACH and debit/credit card.

You can also reject the transaction in the Pending tab if the account does not need to be funded. Since the account is already open when it’s moved to “Pending” status, no email notification is sent to the applicant when a transaction is rejected from the Pending tab. Select one or more boxes next to the transaction(s) you would like to reject and select Reject.

Note: Rejecting the pending transaction does not update the application or account status. You cannot resubmit the application once it is rejected.

If you try to approve a transaction while the NACHA file is actively processing, you receive an error message instructing you to try again later.

Error message indicating ACH modification is not allowed during processing period.

Hard Reject of Application

You can also approve or reject the application from the transaction details, including a hard rejection.

To do this, select the applicant row, and in the panel that opens, select the 3 dots > Approve transaction or Reject transaction.

  • If the applicant does not have funding attempts remaining, the only option is Reject application.

You can also provide an optional reason for the rejection. Select Submit to finish. Once rejected, the applicant receives an email notification.

Manually Process AO ACH Transactions

Your staff may need to manually process AO ACH transactions if your institution does not have automatic ACH processing set up with Narmi, or if it has automatic processing but chooses to process transactions manually. When processing a transaction manually, we ensure it is not included in the end-of-day to prevent duplicates.

To manually process AO ACH transactions:

  1. Approved transactions show in the Pending tab. Select one or more boxes next to the transaction(s) you would like to process and select Manually Process. The transaction(s) automatically move to the Processing tab.

Handling Manual Core Reversals for Rejected Funding Transactions

In some instances, an account opening transaction may be rejected by FI staff after a posted entry has already been recorded on the core. Because ACH returns are processed through the Fed (external to the Narmi platform), these reversals cannot be automated within the Narmi platform and require manual intervention on your core system.

Why does this happen?

When an applicant funds a new account, Narmi initiates the transaction and places an ACH hold on the funding amount. This hold is a protective measure to ensure the transaction clears before the funds are fully accessible.

If the transaction is ultimately rejected — most commonly due to insufficient funds in the source account rather than fraud — the following manual steps must be taken to reconcile your ledgers.

Action Steps for FI Staff

If you identify a rejected transaction that has already been posted, please follow your internal standard operating procedures to complete the following:

  1. Manual Core Reversal: Reverse the deposit entry to the new account and the corresponding offsetting General Ledger (GL) entry.

  2. Manage Holds: Delete the existing ACH funding hold.

    • If the account is to remain open while awaiting alternate funding, determine if a full balance hold is required per your FI's risk policy.

  3. Account Status: Decide whether to close the account immediately or keep it active.

  4. Member/Customer Outreach: Reach out to the individual to:

    • Notify them of the rejected funding.

    • Request they visit a branch or send an alternate funding method by a specific date/timeframe to keep the account active.

Note: While these rejections require manual work, the majority of these cases are caused by simple insufficient funds in the external account, not malicious intent.
