To switch users and end a shift, open the Menu in POS, then click on the logged in user name.
Switching users and ending a shift requires in-store manager permissions (set in Admin Settings).
You must end any open shift before another user can start one.
If you have an open shift, you will have to end it before switching users.
If connected to a receipt printer, ending a shift will print a summary of the shift just ended.
Now you can select another user or log in a new user.
