They paid on Pix, but the money did not fall: how to avoid scams on the cashier

In March of this year, a case that circulated among trade associations drew attention: a small shopkeeper finalized a sale after the customer presented a scheduled Pix voucher. The payment was never completed, and the loss only appeared hours later. Situations like this have been repeated and happen in parallel to recent changes announced by the Central Bank of Brazil, which in February 2026 updated Pix security mechanisms, including adjustments to the return process in cases of fraud.

For Reginaldo Stocco, CEO of vhsys, the most common mistake is to treat the voucher as payment confirmation.“The only sure way to validate a sale is to confirm that the value has actually entered the company account and this needs to be part of the process, not the interpretation of who is in the” cashier, he says.

In practice, avoiding this type of scam involves organizing the flow of receipt clearly and objectively. The first step is to define a simple rule: the sale is only completed when the payment appears in the financial system or on the statement in real time. This eliminates decisions based only on the appearance of a voucher and reduces the risk of error in times of greatest movement.

Another important point is to standardize the behavior of the team. The cashier needs to know exactly what to check before releasing the sale: identify if the Pix was actually completed (and not just scheduled), check if the amount received corresponds to the purchase and avoid validating payments only for images sent or presented by the customer. When this process is clear, the chance of fraud decreases.

The technology comes as a direct reinforcement in this routine. Management systems that connect to the bank allow to automatically follow the payment entries, reducing the need for manual conferencing.This means that the system itself signals when the value was received, bringing more security and agility to the operation, especially in businesses with high sales volume.

“When the process is well defined and supported by technology, the risk is controlled by the operation itself. This is what protects the cashier on a daily basis, without locking the sale and without complicating the service”, concludes the CEO.
