Q.) One of our ACH Origination customers is getting ready to distribute annual bonuses and some are rather large. What is the maximum dollar amount allowed per transaction?
A.) The size of the field that holds the dollar amount of a transfer through the ACH system is 10 digits (8 digits for the dollar amount and 2 digits for cents). So there is a maximum amount of $99,999,999.99 for a PPD transaction (2021 ACH Rule Book, page OR108, PPD Entry Detail Record, Field 6). Keep in mind, the answer is different for Same Day ACH transactions as the current per transaction limit is $100,000.
