@user62652  Hi there I can help you with that question.

Here are steps to take to disable the feature for online payments on invoices:

1. Sign in to QuickBooks Online.
2. Click the Gear icon on the upper right hand side.
3. Under Your Company, select Account and Settings.
4. Click the Sales tab.
5. In the Customize section, click on Customize look and feel.
6. From the Custom form styles list, click Edit on the template to modify.
7. Click the Payments tab.
8. Click on the payment method(s) to disable.
9. Select Done.

It might seem as if the boxes reverted to their original state but once you create a new invoice you'll see the boxes on the invoice template are no longer checked for online payment processing.

You can also enable/disable card and ACH processing from individual invoices, QuickBooks Online is designed to memorize settings from prior transactions.

Let me know if this helps!
