I'm looking for an "advance payment" option for a event but I have not found it.
I don't want that the person pays the total price of the event, but just an advance payment when he registers.
Is it possible ?
No, we don't allow forcing it. However, you can go to Events Booking -> Configuration, set Default Payment Type config option to Deposit Payment so that Deposit payment will be selected by default. That should work better fir your need
