You have the ability to switch between the different modes of the entrée invoicing system without having to close down the existing window and return the main menu of the entrée system.

 

This button will only be enabled when there is no data loaded in the invoicing window.

 

When this button is clicked a menu will be displayed showing the available invoice modes for the user.

 

If an option is disabled, it is because the user does not have the proper security privileges to access that item.
