Pay a Square Invoice Using ACH

ACH bank transfer is a payment method that Square offers to pay invoices from a bank account. If you receive an emailed or manually-shared invoice from a merchant using Square, you can pay it online using an ACH bank transfer if the merchant allows. Square has partnered with Plaid to verify your online banking credentials.

To pay invoices with Square using an ACH bank transfer:

1. Begin by clicking Pay Invoice in the invoice notification message or email.

2. Select Pay by bank transfer (ACH).

3. Use instant verification to verify your bank account.

4. Continue through the verification process and click Continue.

5. Confirm the account and authorize the payment.

We recommend paying your invoice within 30 days, but the merchant may include different payment terms. Make sure to read through the invoice thoroughly, and follow the merchant’s instructions. If the merchant has tipping enabled, you’ll also see the option to include a tip with your payment. You can add a tip of up to 50% of the invoice total.

Update Your Bank Account 

If you receive a recurring invoice series from a Square merchant, you also have the option to update or change the bank on file. To update your bank account information:

1. Open the last invoice email you received from the Square merchant.

2. Click Update payment method in the invoice notification email.

3. Review the information at the top of the screen to verify that you want to change the bank account being used.

4. Select the option to Update bank transfer (ACH).

5. Verify your account and click Continue.

6. Check the box authorizing the business to store and charge this bank account for future purchases.

7. Click Update.

You can also update your bank account on file by making an early payment.

1. Open the last invoice email you received from the Square merchant.

2. Click Make early payment.

3. Select the option to Update bank transfer (ACH).

4. Verify your account and click Continue.

5. Check the box authorizing the business to store and charge this bank account for future purchases.

Save Bank Account Information on File

If you would like to save your bank account information for future payments, including those outside of a recurring series, you may save your bank account information to your buyer profile. This expedites the process of approving future invoice payments by removing the need to add your bank details each time you make a payment. Instead, you simply approve or reject any charges via a notification that appears during checkout.

Remove Your Bank Account

To remove the bank account being used for an Invoice:

1. Click Update payment method in the invoice notification message.

2. Select Remove bank on file.

3. Review the information in the pop-up and select Remove.

4. You will receive confirmation that the bank on file successfully removed.

If the invoice is not fully paid off, be sure to update payment information for the rest of the series. The series will no longer automatically charge your bank account.
