I suspect that an employee are making sells and do not register the selling using remove items option but stealing the money from the customer making a false selling.
There is any log when a cashier use "remove items" when selling?
Hello there @cabreramouzo
I am sorry to hear about your situation. You might be interested in the Activity Log.
The Activity Log in your online Square Dashboard allows you to monitor sensitive actions taken by your team members — such as processed refunds, updates to item inventory, comps/voids, and discounts.
With Team Management, you have free access to view the time and location of each action taken in your Square app and Virtual Terminal. By upgrading to Team Plus, you’ll also be able to view and filter actions by a team member. With this more granular reporting, you will be able to see which team members are issuing refunds, comps, discounts, updating inventory, and voiding transactions.
I hope this information is helpful!
