When the customer order is to captured during pickup and the payment is processed (cash, card etc). During the payment processing, the inventory is checked and the customer order error comes up with an error incase the customer order is not rightly processed in the warehouse or the stock is not available. In this case, the payment is already captured and the sales order cannot be closed.

From the customer side, we have the issue that inorder to void the transaction the payment needs to cancelled. Our Business transactions involve high amounts which creates problem for card payments. Cancelling a high amount and processing again would mean the customers card can be declined due to the limit. Hence, a customer order check and error display asking whether the payment be processed before the capture of the amount would avoid this issue of needing to void the payment.
