ACH Direct Debit

Sellers can accept payments from buyers using a US-based bank account. These payments are referred to as ACH Direct Debits.

ACH Direct Debits as an alternative to credit and debit cards. ACH Direct Debits are processed using the Automated Clearing House (ACH) payments system operated by Nacha.

ACH Direct Debit Payments

Unlike credit card payments, ACH Direct Debit payments are not a real-time payment method. It can take 4-10 business days to fully authorize the transaction with the buyer's bank and confirm if it failed or succeeded. Buyers can dispute the transaction up to 60 days from the initial payment date.

To process a payment using ACH Direct Debit, collect the following from the buyer and create a Payment Instrument:

You can collect this information using our API or our Tokenization Forms.

ACH Direct Debit States

You can review the three states for ACH Direct Debit payments below. ACH Direct Debit payment gets created with Transfer#state PENDING:

ACH Timing

ACH Direct Debits take longer than credit card payments to move and settle funds. To account for this, Finix creates a delay to accommodate any ACH Returns that could occur. This delay is called an ACH Settlement Delay.

By default, Finix puts in a 5-day delay before ACH Direct Debits can settle and become available for approval in a Settlement.

Sellers may want ACH Debits to appear in settlements faster or slower based on their business. For example, the ACH Settlement Delay can be:

• Decreased, so ACH Direct Debits appear in Settlements faster. This can result in ACH Returns appearing after paying out an ACH Direct Debit.
• Increased, so sellers have more certainty before paying out ACH Direct Debits. This helps make sure payouts to sellers always include ACH Returns.

To configure or change this delay, reach out to your Finix point of contact or email the Finix Support team.

Validating Bank Accounts

In compliance with Nacha's bank account validation rule, Finix validates every bank account before proceeding with any ACH transactions. Finix validates the bank account the first time it's used, or after any change gets made.

The Transfer#bank_account_validation_check field details the results of this validation check. The following values get returned for Transfer#bank_account_validation_check when creating an ACH Direct Debit:

ACH Direct Debit Authorization Language

Before processing any ACH Direct Debit payments, the buyer must agree to the following statement:

By clicking submit, you authorize us to initiate an automated clearing house (ACH) one-time debit in your name to your bank account indicated above. The amount of this transaction as noted above will be presented to your financial institution by the next business day. You further agree that once you click submit you may not revoke this authorization or cancel this payment.

We recommend presenting this language in your checkout flow right before the buyer clicks the Submit button and triggers the creation of the payment.

ACH Direct Debit Confirmation Language

After the payment is submitted, present a confirmation screen and/or email a confirmation to the buyer with the following language:

Thank you for your payment in the amount of $xx.xx. Please print this authorization for your records.

You have authorized us to initiate an automated clearing house (ACH) one-time debit in your name to your bank account. This transaction will be presented to your financial institution by the next business day. You further agree that you may not revoke this authorization or cancel this payment.

Failed ACH Direct Debits

An ACH Direct Debit can fail for a variety of reasons, including:

• Incorrect or Invalid Account Number.
• Buyer's bank account blocks ACH Direct Debits.
• Insufficient funds from a buyer's bank account.
• Buyer files a dispute on a payment they didn't agree to.

When a ACH Direct Debit fails, Finix creates an ACH Return to recover the original payment amount.

ACH Returns are represented by a Transfer with:

• Transfer#type : REVERSAL
• Transfer#subtype : SYSTEM

A full list of reasons why an ACH Direct Debit can result in an ACH Return is available below.

The details of ACH Returns are available to review in the Dashboard.

Creating an ACH Direct Debit

First, create a Payment Instrument to represent your buyer's bank account. Use our Tokenization Forms to collect the buyer's bank account and payment details.

Create a Transfer with the Payment Instrument you created to debit funds directly from the buyer's bank account.

• ACH Returns create a Transfer with Transfer#type REVERSAL and Transfer#subtype SYSTEM. This Transfer subtracts the amount from the actively accruing Settlement .

Refunding an ACH Direct Debit

Refunding an ACH Direct Debit is similar to refunding a Transfer. Use the /reversals endpoint to create a Transfer that moves funds back.

Create a Transfer reversal using the Transfer#id of the original ACH Direct Debit that you want to reverse.

A successful response returns 201 and a new Transfer with type REVERSAL. The original Transfer#id is listed under _links#parent at the end of the URL.

The Transfer#state gets updated to SUCCEEDED when the refund gets processed. Buyers will see the refund returned as a credit within 5-10 business days, depending on their bank. ACH Direct Debit refunds can’t get canceled once processed.

ACH Refund Returns

Banks manage the ACH networks and often pre-fund transactions before debiting funds.

In some rare cases, an ACH Refund can get returned if the buyer:

• Account is closed or frozen.
• Makes a mistake while entering their bank information.
• Requests to reverse a pre-funded transaction.

When an ACH Refund gets returned, two Transfers get created to credit the funds back to the original bank account. The webhook events you receive, include the subtype:

• MERCHANT_CREDIT: one Transfer to return the funds back to the original bank account.
• PLATFORM_DEBIT: one Transfer to debit funds that got credited proactively.
