Can't figure out how to bill returning guest for a deposit

Hi, I am trying to process a booking for a return guest. They asked me to send them the booking/payment info this week, as they just left the cottage on the 31st. I had blocked off the desired dates in 2019 and converted it to a booking using the same prices as last year. I'm trying to send them a request for the $500 deposit, but I don't see that as a choice. I have successfully created the booking but the only choice I have is to bill them for the full amount. The customer's last name is Elmore. Can you please help? Thanks!

Go to the Transactions tab of the booking and click Request > Request Payment. That'll send them a payment link they can use to pay. It'll tell them the total and let them pay more if the want to, but the minimum payment will be the $500 deposit. Hit the preview button in that modal before you send the email and you can see what the guest will see.

Thanks so much. I was able to send them a custom message with what was required now and what would be required in the future and when. I appreciate the fast response, Chris!
