If you require your staff and agents to enter a confirmation number with each point of sale booking, you can enable the confirmation number field. First, navigate to Settings in the main menu and click System Configuration.
1. Locate the Confirmation Numbers dropdown in the Point of Sale section.
2. Select Require confirmation numbers for all Point of Sale purchases.
With this enabled, a required booking confirmation field will be added to the point of sale, and will need to be filled out before completing every POS booking.
