Delivery drivers can be assigned a starting cash balance that acts as a soft bank throughout their shift. At the end of the shift, the driver cash bank is returned to the house as part of their cash on hand.
This is a set amount that is configured in the Takeout / Delivery settings under Other Setup.
To ensure that the employee will see their driver bank will be accounted for in Shift Review, navigate to UI Options in Other Setup and make sure that Delivery is selected in Shift Review Report Configurations.
As shown below, the driver bank will appear under Cash in Hand. The amount that the employee owes the house will include the driver bank amount.
