How to Select a Cash Drawer Open the register or the Shift area. If no cash drawer is selected, choose Select Cash Drawer. Pick the drawer that matches the physical till your register will use. Continue to Open Shift. If several computers should share one shift, select the same drawer on each. If each register must balance independently, select a different drawer for each register. You can change the available drawer records in Settings → Shift → Cash Drawer. Confirm the drawer before processing sales so activity is recorded in the intended shift.
