Will my guest be sent a payment request for the security deposit due?

You must have payment connected and using the charge through Houfy option in order for Houfy to automatically send payment request to your guests.

If you opted for the deposit to be collected "At Booking" then the guest already paid it with the initial payment. For all other options an automatic payment request is sent. The host will receive a copy that it is sent as well.

How soon before the due date is the payment request sent?

Will I be notified when my guest pays the payment request?
