Final answer:
A customer typically has a certain period of time to request an ACH reversal, usually within 60 days but may vary depending on the circumstances.
Step-by-step explanation:
A customer typically has a certain period of time to request an ACH reversal. This time frame is determined by the NACHA Operating Rules, which govern ACH transactions in the United States.
According to the NACHA rules, a customer generally has up to 60 days from the date of settlement to request an ACH reversal. Settlement refers to the date when funds are debited from the customer's account. However, there are some exceptions to this rule. For example, if the customer claims an unauthorized transaction, they may have up to 90 days to request an ACH reversal.
It's important to note that each financial institution may have its own policies regarding ACH reversals, so it's always best to consult with your bank or credit union for specific information.
