Payment by Credit card

If I want to pay by credit card how do I reference an invoice against it without registering an invoice in the Accounts Payable?

If the invoice does not exist why do you want to reference the invoice?

Ok fair comment as I am working out scenarios… but is it possible to reference something when making a payment by CC on ax?

There are fields you can use as reference, so yes, but obviously not referencing something in another table that does not yet exist.
