What it does
The manager's side of the till: create and disable cashier logins, watch open shifts, force-close a shift someone left open, browse sales history, review per-cashier performance, and issue refunds or voids. A refund normally restocks the items, but a "Return items to stock" checkbox can be unticked when nothing physically came back — a goodwill refund, something damaged or already consumed, or a refunded service.
