How can I create new Boost Business account under “Supervisor” and “Over the Counter Staff”? Jack Follow 1. "Manager", "Supervisor", "Cashier" cannot be added from the Boost Biz App. Instead, please use the browser to access Boost Biz web portal for team/user management. 2. Add/remove/edit user access can only be done by "Manager" and "Owner". Please refer to Boost Biz Web Portal FAQ.
