When a new user is created in Mews, you need to decide whether this user will be allowed to accept cash. If this is the case, the employee MUST be assigned a cashier, otherwise he/she is not allowed to accept cash in Mews.
How to set this up afterwards? The ADMIN of the hotel is able to follow the next steps to assign a cashier to a user.
Simply click on "Settings" and "Employees" and find the employee you would like to assign the cashier to. Click on the employee name, and select the cashier you would like him/her to have access to and save the new setting.
Note: Unfortunately the Mews support desk is not able to do this task for you, as the ADMIN of the hotel must decide whether an employee is allowed to accept and post cash in the system.
