Thanks for joining us here in the Community. I'm happy to walk you through the process to disable the payment processing box in QuickBooks Online.

This can be done in just a few steps. Here's how:

1. Click the Gear icon in the top right corner.
2. Go to Account and Settings.
3. Select the Payments tab.
4. In the Payment Methods section, remove the credit card or ACH.

You can also delete the credit card payment through the Payment Methods page. In the credit card section, select the Make inactive option under the Actions column.
