What term describes fraud involving an employee ringing up no sale transactions while taking cash?

The term that accurately describes fraud involving an employee processing no sale transactions while taking cash is "unrecorded sales." This term refers to instances where employees manipulate transaction records to conceal the actual number of sales made, often resulting in the employee pocketing cash without any corresponding sales record. This form of fraud allows the employee to create a discrepancy between the cash taken in and the recorded sales, which may not be immediately obvious to management or accounting practices.

In contrast, the other terms provided do not specifically apply to this form of fraudulent activity. "Check for cash substitution" usually relates to methods of embezzling funds using checks rather than cash transactions. "False transaction" refers broadly to any fraudulent recording but doesn't capture the specific detail of employees taking cash without a corresponding sale. "Mail room theft" specifically pertains to stealing items from the mail room, which is unrelated to cash transactions made at a register or point of sale. Thus, "unrecorded sales" is the most precise and relevant term for this scenario.
