This document describes the user interface for the billing codes application.

If the user has more than one billing code assigned, the billing code application appears in the last step of the authentication process.  If the user has only one billing code assigned, the billing code is automatically selected without the billing code selection process.

My Billing Codes

This is the first screen a user sees after opening the billing codes application.

When a default billing code is assigned, the billing code is already selected.

Otherwise, the user will see an information message instead of a billing codes list.

The user can browse or search other billing codes by tapping Browse.

The user can select the highlighted billing code by tapping Select. This will also close the application.

The browsing screen displays a billing codes tree structure which can be used to find and select a billing code.

1. First, the root level of the billing codes tree structure is listed.
   
2. Navigate to a billing code using the navigation buttons.
   Navigate down the tree structure by tapping on the right side of a billing code. It is available only for billing codes with at least one child billing code.
   Navigate up to the previous level of the tree structure by tapping .
   Display the root level by tapping .
   
   
3. Highlight a billing code by tapping it. The Select button becomes enabled and by tapping it the user selects the billing code and continues.

The searching screen displays a billing codes list of all matching billing codes. The billing codes with at least one child billing code have the folder button on the right side of the billing code. Use the folder button to go down the billing codes tree structure.

Default Billing Code

Depending on the user's configuration, the default billing code is selected automatically immediately after login (in this case: 0: Default Project). Until the user changes it, all copies, scans, and prints will be accounted to the user's default billing code.
