one (1) time bank (ACH) payment authorization form allows a business to make a single withdrawal from a customer’s checking or savings account. The document includes the amount to be withdrawn, the date of the withdrawal, the customer’s banking information, and the customer’s signature. The merchant can add a fee if the withdrawal results in a Non-Sufficient Funds (NSF) payment rejection.



By signing this form, you permit us to make a one (1) time debit from your checking or savings account for the amount indicated on or after the indicated date. This is permission for a single transaction only and does not provide authorization for any additional unrelated debits or credits to your account.

I, [CUSTOMER NAME], authorize [MERCHANT NAME] to charge my bank account indicated below for $[AMOUNT] on [MM/DD/YYYY].

This payment is for the following: [REASON FOR PAYMENT].




Account Type: Savings | Checking
Account Name: [ACCOUNT NAME]
Bank Name: [BANK NAME]
Account Number: [ACCOUNT #] Routing Number: [ROUTING #]


I understand that because this is an electronic transaction, these funds may be withdrawn from my account as soon as the above-noted transaction date. If the payment is rejected for Non-Sufficient Funds (NSF), I understand that the Merchant may, at its discretion, attempt to process the charge again within thirty (30) days. I agree to an additional $[NSF CHARGE] charge for each attempt returned NSF, which will be initiated as a separate transaction from the authorized payment. I acknowledge that the origination of ACH transactions to my account must comply with the provisions of U.S. law. I will not dispute the Merchant so long as the transaction corresponds to the terms indicated in this agreement.

Account Holder Signature: _________________________ Date: [MM/DD/YYYY]
