We offer no payments outside of Intuit Payment Processing.  No physical card swipes. Nothing.  Client must pay through Intuit's web link on invoice.

Look, you pay Intuit to do your payments exclusively, and they won't certify that they are PCI compliant, that's kind of a problem.

People in my situation should merely sign / declare they take no payment information (ever) and outsource the entire payment workflow to Intuit.  DONE. 

Intuit's refusal to answer this clearly can only be explained by:

• Their legal department has reasons we don't know about
• Their staff are not trained and don't know what they are talking about beyond the required script.
• Intuit receives a commission for every customer they refer to the external compliance company.
• There is a Federal rule we don't know about.

Regardless, Intuit should be forthcoming instead of the run around.
