Post-payment voids
A post-payment void is fraud in which the customer pays, takes the product and, once they leave, the cashier voids the sale or some of its items at the POS. The record shows a cancelled sale, and the money collected, almost always cash, stays out of the register closeout.
How it happens
The customer pays in cash, gets their change and walks out. A few minutes later the cashier voids the receipt or some items, claiming a keying error. The system now shows a sale that never completed, although the product has left inventory. The gap between what was paid and what was recorded stays with whoever voided it.
Warning signs
Void with no customer at the register
The void happens after the customer from that sale has left the checkout.
Cash sale reversed
The voided sale was paid in cash, and the product was bagged and handed over.
Remote approvals
Voids are approved in a row without the supervisor or manager present at the register.
Recurrence by POS
Voids repeat at the same register or the same time of day, above the pattern of other stores.
Where it shows up
It shows up in operations with heavy cash payments and voids approved at the register itself, from the grocery checkout to the restaurant counter.
How the Bewacher agent is designed for it
The agent reads every void the POS records and looks in the checkout video for the moment of the original sale: whether payment was made, whether the product was handed over and whether the customer left before the void. The rule combines value, payment method and the time between sale and void, tuned to each chain's operation. The validated case reaches loss prevention with the receipt and the video clip together, and no one is identified.
Terms in the glossaryFrequently asked questions
Is every void suspicious?
No. Voids are part of register routine, from scanning errors to customers changing their mind or their payment method. The agent assesses the context of each void. A void made after payment was collected and the product handed over, with the customer already gone, goes to review.
Why doesn't the register closeout catch this fraud?
The register closes with no difference: the voided sale leaves the record, its cash leaves the drawer at the same time, and the totals match. The loss surfaces in inventory later, with no trace of its source. That is why the reading has to bring the receipt and the video of the moment together.
Do restaurants see this kind of fraud too?
Yes. In the dining room and at the counter, a check paid in cash can be voided or reopened after the guest leaves. The agent applies the same logic, matching the void with what the video shows of the service and the payment.
