To collect the full payment from your clients during the Finalization (or Finalisation) Process in a single transaction...  

You simply need to set the "Deposit" amount in your pricing grid to match the total price of the event.

When you do this, your Booking Finalization Form, will automatically request payment for the "Full amount".

Note: this process will be further improved upon soon, but we wanted to give you the functionality you needed NOW 🎉
