If all we are doing is submitting an invoice on Quickbooks, Quickbooks sends the payment link and invoice, Quickbooks processes the payment, and Quickbooks transfers that payment (less fees) to my bank account, we have zero involvement in the actual payment processing/credit card transaction. We have zero exposure to, or control of, that card data. As such we are not required to be PCI Compliant and Quickbooks needs to address this annoying issue.
