The "Deposit Amount" that shows on the manual PayBridge Credit Card link can be changed. This is used in order to show the guest what amount they should be paying to secure their booking.
To change the amount that displays to the guest, you will need to update the deposit amount on the booking in your calendar.
Edit the value in the "Deposit" box.
In the amount field, next to the Calculate Deposit button, manually change the amount to whatever the guest needs to pay.
