how do I turn off payment for customers to pay thru quickbooks

Hello there, rktodd. You can toggle this feature off for a specific customer within the invoice itself. Just scroll down to the Customer payment option and hit Edit to toggle those payment options off before sending out your invoice.

If you wish to turn it off for all future invoices, click the Gear icon and select Account and settings. From there, go to the Sales tab and then the Invoice payments section to toggle off the options for credit cards, PayPal, or bank transfer (ACH).
