PayPal payables accounting - paying a bill

Quickbooks Online: We are a non-profit (church) using PayPal to receive donations and transfer the balance once a month to checking.  One or two times a month we also make a payment using PayPal, ALWAYS paying directly from the checking account, NEVER paying from the PayPal balance.  Here we have two scenarios:

(a) most often the payment is recorded simply as an Expenditure, so the checking account can be listed as the Payment account and PayPal can be listed as the Payment method, but then there is occasionally:

(b) a Bill is being created first. But then, under Pay bills, there is no distinction between Payment account and Payment method, there is only Bank/Credit account (which we list as our checking account), and at "Ref. No." we type in "PayPal."

Is (b) an OK way to handle the formally billed expense?
