A customer emails after paying — they want one more dozen eggs, or they ordered two heads of broccoli instead of one. Until now, every tweak to a paid retail order meant asking an admin and waiting. Now you can handle it yourself from the Order Details page: change a line item's quantity, remove an item with an optional account credit, add more items from your shop, issue a standalone credit or debit, refund a pickup or delivery fee, or cancel and credit the whole order in one action. Customers get the standard notification when a change affects their invoice, inventory updates stay optional on each edit, and everything is recorded in the order's audit log.
