I note that the 1SC plugin says, "Once payment is finished, 1ShoppingCart will report sale back to aMember." If we use manual (offline) card processing, if we go back to 1SC and note that the sale was completed, will 1SC report back to amember that the payment went through?
Ah, are you about a 1SC feature? If so, it is better to ask 1SC support, but I guess answer is "yes".
