A void or comp abuse is the misuse of the POS functions that cancel or discount a sale — used occasionally they’re normal operations, but a pattern of them is one of the clearest signals of profit leak. A healthy void rate is generally benchmarked under 1–2% of sales; consistently higher points to error or intent. On its own a void is ambiguous. Lined up against who was on the clock and how the drawer closed, a pattern separates itself from an honest slow night — which is exactly the correlation a single-system tool can’t make. It points you where to look; it never concludes wrongdoing.
