Great timing, this was something I was moving to look in to next.
In my dive shop we have only one till, but several terminals where we prepare customer bills and also record expenses using SambaPOS. We don’t have many til operations throughout the day, and because some of the terminals are nowhere near the actual till I don’t have any rules to automatically open the cash drawer, instead I have an “Open Drawer” button always visible and the usage of this button is logged.
We are often over of under at the end of the day, but it is nearly always something stupid (in a manic rush, we forgot we took a payment, or paid an expense). So the cash drawer log will help to narrow down what section of the CCTV need to be reviewed. But mroe of a ticket action log, coupled with the cash drawer log will really help me identify the times we open the cash drawer without having just settled a ticket.
