1. Open the order and find the item in its module table (Packs, A la Carte, Extras, Products, Gift Card, Custom Charge, Labor & Equipment, Grab and Go, POS Menu, Real Time…).
2. Click Refund in that row's Actions column and confirm Are you sure?.

The item's price is credited to the customer's digital wallet (Partial Refund #<order>), the row turns red/struck-through, the order status becomes Partial Refund (or Total Refund if that was the last unrefunded value), subscription meal counts are updated for subscription meals, and the customer receives the refund email naming the item. Grouped rows show one Refund link per unit, so you can refund one of three identical meals. Custom meals, by-the-pound and venues do not have a per-item refund link.
