I have been trying to solve this problem for a while now. I am using HSBC API Payment module and it sets the order to Processing after an order is placed, the other option is Pending.
I also have the “Decrease Stock When Order is Placed” option under Inventory set to yes.
But the stock does not decrease unless the order is marked as completed. I would like the stock to be decreased straight after a successful transaction.
Really appreciate if anyone can recommend anything.
