If you have already selected a way of pre-payment with VRBO that you wouldn't like to use anymore, please follow the process below.
For example, you currently have "Flat Amount Per Stay" selected, and you would like to set it to "100% of the amount Pre-Payment":
As you can see, on this account the set up is "Flat amount per stay" as a pre-payment method and "0"as the amount required. Please note that if you would like to have 100% pre-payment, you need to first deactivate the connected properties, then select "Percentage of the total price" and insert "100%" in the value box next to it:
Finally, activate the properties again and VRBO will sync the data after a few hours.
