Thank you for posting your concern here in Community, @zylstra.
In QuickBooks Online (QBO), the intuit processes payment doesn't share the customer's bank account details with the merchant. A merchant can only see the payment confirmation and other non-sensitive details such as the amount paid, date, and status of the transaction.
If a merchant uses QuickBooks Payments merchant services, QuickBooks (Intuit) is the payment facilitator that handles the transaction securely. Merchants using QuickBooks Online and QuickBooks Payments do not have access to the customers' bank account numbers or other sensitive financial data. This setup helps protect the privacy and security of customers while allowing merchants to receive payments in a streamlined manner.
As QuickBooks is PCI compliant, protecting customer payment information including their bank information is a must.
