Void rate
Void rate is the share of items rung up then voided before payment, measured per cashier per shift. F&B baseline is 1–2%; sustained >3% on one cashier is a shrinkage red flag. LOOP runs a void-rate anomaly detector and pings the manager within hours instead of waiting for end-of-shift reconciliation.
Formula
Void rate = items_voided_pre_payment / items_rung × 100, sliced per cashier per shift.
Void rate in day-to-day operations
Operators meet void rate at three moments: when a system is first configured, when a second outlet opens, and when margin is reviewed. At each point the practical question is not the definition but who owns it, where the data lives, and how quickly a discrepancy surfaces.
If void rate lives only in a spreadsheet or in a manager's head, it drifts. When it sits in the operating system alongside tickets, recipes, payments and delivery commission, a discrepancy shows up the next morning instead of at month end — and that gap is where the money is.
LOOP handles void rate inside the same POS, KDS and inventory platform, running on devices you already own rather than dedicated hardware. Browse the full F&B glossary or see LOOP pricing.
What is Void rate used for in F&B operations?
In multi-outlet restaurant and F&B operations, void rate is an essential component — directly affecting service speed, order accuracy and margin. See the related terms below to understand where it fits in the broader stack.
How does LOOP support Void rate?
LOOP supports void rate natively in its POS + KDS + inventory platform for Vietnamese F&B chains — no plugin or third-party integration required. It's one reason multi-outlet operators pick LOOP as their primary operations system.
