A void is the cancellation of an item or an order after it has been rung into the POS. Voids are tracked because a pattern of them — by person, by shift, by item — can indicate a training issue or a control problem.
Voids are normal. A guest changes their mind, an item is rung to the wrong table, a dish goes back. What matters is that each one is attributable and visible.
In a high-cash environment such as a bar, void reporting is often the single most useful control a POS provides — not because you distrust staff, but because an unexplained pattern needs to surface rather than stay buried.
