What Is a Void in a POS? (Void, Cancel, NC) — India Guide

Void, Cancel, and NC — What Each Means

These three terms describe different ways an item leaves or changes on a bill, and mixing them up is a common source of confusion on the floor.

A void removes an item that was already entered into the POS — for example, a dish punched to the wrong table, or a starter the guest sent back to the kitchen. A cancel usually refers to dropping an item before it has been prepared, so the kitchen never makes it. An NC (no-charge), also called a complimentary or 'comp', keeps the item on the record but sets its price to zero — the dish is served but deliberately given free, perhaps to recover a service mistake or as goodwill.

The practical distinction is money and food. A cancel ideally happens before food or cost is incurred; a void reverses something already entered and possibly already cooked; and an NC gives away a real, prepared item for free. All three reduce what the guest pays, which is exactly why they are watched closely.

• Void — remove an item/order already entered in the POS
• Cancel — drop an item before the kitchen prepares it
• NC / No-Charge / Comp — serve the item but charge ₹0
• Sent-back dish — a common, legitimate reason to void after a KOT

Voiding Before vs After the KOT Fires

Timing changes what a void means for the kitchen. If an item is voided before its KOT reaches the kitchen, nothing is lost — the dish was never started, no ingredients were consumed, and it is effectively a clean cancel.

If an item is voided after the KOT has fired and the dish is already being cooked, the food cost is real even though the guest is not charged. That prepared-but-unbilled dish is a genuine loss to the restaurant, so post-KOT voids deserve more scrutiny than pre-KOT ones.

A good POS distinguishes the two cases and records them differently, because a kitchen that has already plated a dish needs to know it is being pulled, and an owner reviewing the day needs to see how much prepared food was voided rather than sold.

Why Voids Need Audit Trails and Manager Authorisation

Voids and no-charges are one of the most common mechanisms of theft in restaurants. The classic pattern: a guest pays cash for an item, the staff member serves it, then voids it off the system and pockets the cash — the POS shows the item was never sold, so the till still balances. Untracked comps work the same way.

The defence is not to ban voids — they are a legitimate, everyday part of service — but to make them visible and accountable. That means two things working together: an audit trail that logs every void (which item, which bill, which staff member, what time, what reason) and manager authorisation, so a void cannot be done silently by the person who took the order.

When every void carries a reason code and a name, patterns surface fast. A single waiter with a high void rate, a cluster of voids just before shift-end, or repeated 'guest cancelled' reasons on expensive items are all signals an owner can act on. Without a log, that theft is invisible.

• Who — the staff member who initiated the void
• What — the exact item and bill affected
• When — a timestamp, before or after the KOT
• Why — a reason code (mis-punch, sent back, cancelled, comp)
• Approved by — the manager who authorised it

Voids, the Bill, and GST

A void must flow through to the final bill correctly, because the GST is calculated on what the guest is actually charged. If a dish is voided, its value — and the CGST and SGST on it — must come off the invoice cleanly, so the tax is computed only on what was genuinely sold.

This is why voiding on paper bills is risky: scratching an item off a handwritten bill leaves no record and makes the tax maths unreliable. A digital POS recomputes the taxable value the moment an item is voided, so the invoice always reflects the correct, defensible amount.

Keeping a clean, logged history of voids also matters at audit time. The record shows not just what was sold but what was removed and why, which supports honest reconciliation of sales against GST filings.

How RestroFi Controls Voids

RestroFi treats voids as an audited action, not a silent edit. When an item or order is voided, RestroFi records who did it, which bill and item were affected, the time, and a reason — so every removal leaves a trail an owner can review later.

Voids can be gated behind manager authorisation and staff permissions, so a waiter cannot quietly cancel a served item without a manager in the loop. Combined with per-staff reporting, this makes the void patterns that usually hide theft visible on the dashboard rather than buried in a paper bill book.

These controls are part of RestroFi's paid Premium plan, which starts at ₹699 per outlet per month; RestroFi has no free plan or trial. For owners who cannot watch every till in person, an audited void log is one of the most direct protections against shrinkage.
