Safely store a customer's credit card number

When you enter a customer's credit card number, QuickBooks stores it in encrypted form using Extended DES encryption. QuickBooks doesn't cache the credit card number or save it in any other form.

Enter a customer's credit card info

1. In the navigation bar, click Customers (or Invoicing > Customers, or Sales > Customers depending on what you see).
2. Click the customer name.
3. If the Customer Details tab isn't selected, click it.
4. Click Edit.
5. Click the Payment and billing tab.
6. Click the Preferred payment method drop-down arrow and select Credit Card.
7. If QuickBooks doesn't have credit card info for this customer, click No credit card information.
8. Enter the customer's credit card info.
9. Click OK.
10. In the Customer Information window, click Save.

When you select the customer's credit card in a sales transaction, QuickBooks shows only the last 4 digits on the printed sales form to keep your customers' data secure and comply with the latest security standards.
