I have an online store that goes "live" at a particular time. Customers are notified of this time and items are scheduled. Sales all happen very quickly.
The issue I have is as follows:
Product Z has total inventory of 10
Customer A adds 10 items of Product Z to their cart, continues to shop adding more products of X Y etc to their cart.
Customer B adds 5 of Product Z to their cart and checks out before Customer A.
Customer A then proceeds to cart, but Product Z does not show an inventory change until they proceed to payment.
I would like to see if its possible for Customer A to see this when they proceed to check out, rather than once they have completed payment details etc?
thank you
