If you use QuickBooks servers to send invoices which have a payment link directly to QuickBook's web host, who's responsible?

100% - CC security liability rests on QuickBooks.

I do not take CC information through a payment gateway on my web company web host.

If we follow the ambigious answers given here they would have you believe that ANY DEVICE contacting their servers must be secure. However, in the case of invoicing and payments directly through QB's owned servers, their is absolutely no contact with any of my devices.

So following what they are IMPLYING is that any and ALL CUSTOMERS devices would have to be PCI complaint when they go to pay their invoices.

Since my devices do not touch the server for CC payment information and I do not see ANY details of the CC number, security code, name, or even address it sounds like to me that someone here needs to TRAIN their team.
