Turn off autofilling credit card information in QuickBooks Online

We can remove the preferred payment method on the member (customer) profile, CentralOfficeBookstore. 

This will just prevent the information from automatically filling out the customer's payment method when creating an order. 

Here's how: 

1. Go to the Sales menu and click Customers.
2. Select the customer's name.
3. At the upper-right, click Edit. 
4. From the Customer information window, click the Payment and billing tab. 
5. Remove Credit Card as the Preferred payment method. 
6. Click Save. 

You can track your sales by pulling up the Sales by Customer Detail report with the Payment Method in it. This reference will help you in customizing your report. 

I'll be here if you need anything else. Thanks!
