To change how dates are viewed in the ScaleXP platform, go to Settings (top tab)>Profile (left sidebar)>Choose the date format you prefer to see across the ScaleXP system.

Use the dropdown menu to choose from:

Day-Month-Year (British)
Month-Day-Year (American)
Year-Month-Day (International)

Note that this view is specific to you as a user and does not impact how ScaleXP reads dates on bills and invoices, which is set during the initial accounting connection and can not be changed once connected.
