Back on 26 Sept I posted a help question about PayPal fees. Rather tardily, I am trying to implement the excellent help offered by user rhc at How to treat PayPal fees
However, I have a new question. If I follow rhc’s suggestion and post PayPal payments to a PayPal holding account, I lose the ability to tie each received payment to an invoice. I have created these invoices as a way of tying each payment to something purchased - in my case, a subscription.
Not sure if this is critical. Maybe I just dispense with the invoices?
Or maybe there is another way of dealing with the PayPal fee problem?
