Process an Auth-only (Authorization only) transaction in QuickBooks
Authorizations generate a pending transaction on the card holder's account. They generally expire within 1-10 business days but may appear on their account much longer, depending on the card issuing bank's specifications. IMPORTANT: Any authorizations over 10 days old are considered expired and will need to be re-authorized to ensure proper funding.
Open the QuickBooks company file.
On the Customers menu, select Credit Card Processing Activities > Authorize/Capture Payments
Enter the payment information.
Click Save to complete the authorization. Note: The transaction will not be completed until the Authorization is captured in QuickBooks.
