Cash Disbursements feature allows you to either add or subtract money from the cash drawer. These changes will appear in your reports.
You can still pop the drawer by clicking the button labeled Cash Drawer, but there is now an additional drop down option which allows you to add a Cash Disbursement. Simply click the arrow, and select "Cash Disbursements".
Enter a reason for adding/subtracting the cash out, employee name, and the amount. Then hit Submit.
This will create a section on the Sales Report called Cash Disbursements, allowing you to track the amount you take out of the drawer each day and the reason why.
This feature can be enabled by going to Settings > POS Settings > POS Settings and look for Other Options:
