When choosing 1.5% Net15 ACH, PaymentWorks will reach out to confirm your bank details and verify the information you provided is correct. Please be aware that your existing POs (made prior to the registration date) will not be affected; the terms of the PO will remain the same. Only future POs (made after the registration date) will reflect your new payment terms. We cannot make changes to existing POs – those terms will be honored.
