From a true business prespective - for what occurred to an order - it is usual for the trail to be updated to a condition rather than some process deleted or edited.
that is why the cart has the process of status condition updating.
You can comment in as to the reason why you have changed a condition so both you, the customer, and perhaps any revenue governmental agency auditing your sales will know what a condition was changed -
You also have the option to NOT send the new status to the customer but only maintain it in the order status details within the account. The customer would see it if they opened their order status, but they do not get an email notification.
I am speaking only from the normal GAAP ( Generally Accepted Accounting Principles) used by most entities around the world for how financial matters are handled and customer orders are indeed a financial transaction.
