Same Day ACH Business

What you need to know.

What do I need to do:

  • Familiarize yourself with Same Day ACH.
  • Have discussions with trading partners who may wish to send or receive Same Day ACH
  • Plan for how your banking services may be impacted by Same Day ACH

How are my Treasury Management Services affected?

How does Same Day ACH impact my ACH Origination services (pass thru or direct transmission ACH)?

Same Day ACH directly impacts all pass thru and direct transmission ACH.  Files (including pre-note files) may not contain an Effective Entry Date which qualifies for Same Day ACH without prior agreement with the Bank. Please ensure you have the proper controls in place to prevent inadvertent creation and transmission of a Same Day ACH file. 

Any future updates or changes to your software should also be reviewed for compliance with the Effective Entry Date requirements. 

How does Same Day ACH impact my ACH Origination services (template ACH)?

Same Day ACH does not impact any template originated ACH transactions.  These transactions continue to be exclusively next day/ future dated transactions.  Template transactions are initiated using the Payroll, Cash Disbursements, Collections or Tax Payment options within Business Online Banking.  (This applies whether you import data or hand key transactions).

When will Same Day ACH transactions post to Business Online Banking? How will this impact my cash forecasting and reconciliation?

Same Day ACH transactions will generally show as pending in your account by 6:00 pm EST/EDT1 but depending on the time of day received they are not required to be made available until our end of day processing. Other ACH transactions will continue to be received by the bank and memo posted to your account in the morning. 

All ACH transactions for the day impact the available balance in your account and should be factored into your overall cash forecast for the day.  You may wish to contact customers who pay you electronically, to determine if they expect to pay you via Same Day ACH.  If they do, it may be helpful to discuss the parameters for payment notification (i.e. if, when and how you will be notified).

You may wish to have similar conversations with vendors who collect payment from you electronically. Debit items could post to your account the same day they are authorized.  To avoid overdrafts, funds should be in your account before you authorize any payments. 

Our Zero Balance Account service calculates your cash position and transfers funds on your behalf.  This service will factor in Same Day ACH transactions when making those calculations and transfers.  If you do not have Zero Balance Account services and wish to learn more, please contact your Treasury Management representative.

How does Same Day ACH impact my Electronic Data Interchange (EDI) reporting by Same Day ACH?

EDI reporting for Same Day ACH transactions received into your account is provided on a next business day basis.  You are still responsible for applying customer payments as of the days funds are received. 

How does Same Day ACH impact my ACH Positive Pay service?

ACH Positive Pay is not  impacted by Same Day ACH.  Same Day ACH transactions are screened in the same manner as other ACH transactions.  Exceptions are presented at the same time and in the same manner as other ACH exceptions.  The deadline for making a pay or return decision on these exceptions is the same as other ACH exceptions. 

How does Same Day ACH impact my Line of Credit Sweep service?

Line of Credit Sweep is not impacted by Same Day ACH.  Our Line of Credit Sweep service factors in Same Day ACH transactions when calculating the Line of Credit Sweep transaction amount. 

How does Same Day ACH impact my Zero Balance Account service?

Zero Balance Account transactions are not impacted by Same Day ACH.  Our Zero Balance Account service factors in Same Day ACH transactions when calculating the Zero Balance Account transaction amount.
