Suspending an order prevents it from being purged from the current sales data when the day is closed out. The order is retrievable from the Point of Sale terminal and the order can be closed at any later date.
To add the function to the menu in the POS Terminal
Place an order like you normally would. Once the order is ready to be suspended, press the suspend button.
The order will be suspended. It can be retrieved from the POS Toolbar - Functions - 'Suspended Orders'.
From the list of suspended orders, choose your order, then press 'Open Order in Register'
