ACH reports or Debit Card reports? The transaction should debit or credit the customer on the Settlement Date IF it is an ACH report. A Debit Card report will show a pre-auth transaction that is effective for up to 3 business days or until the transaction is posted. The date and time you see there should be the date and time the merchant processed the transaction. (You may also see a "local" date/time which reflects the date/time your processor received the transaction.)
