When your agents books, the prices they see are the net prices. The prices are either based on a fixed price catalogue that you have assigned to you agent, or your regular price catalogue with the discount/commission you have negotiated with your agent.
When a ticket is produced for an agent booking, the ticket shows the net prices, not your rack prices.
You can select whether all tickets from your agent bookings should show prices or should not show prices.
To change whether the prices are shown or not shown on the tickets, select "the name of your company" on the top bar and "settings" from the drop down list.
Scroll to the bottom of the setting page, to a section called "Agent Settings".
There you have a checkbox "Show price on tickets", if the box is ticked the net prices are shown on all of your agent bookings ticket. Remove the checkbox to hide prices from the Agent booking tickets.
