Also agree this is a major need. I want to offer a mental health membership which would include med management appointments but therapy sessions billed al a carte. An option for an automatic invoice to be paid (or deposit) at time of booking an appointment would be a huge benefit to our practice being able to offer that plan.

This would be amazing. Adding that it would be preferred if it could charge either the entire cost or partial amount/ deposit (we can choose what amount by $ or % of total cost).

this would be great. I just started my practice and sending invoices has been manageable thus far, but I can't imagine creating and sending an invoice for every appointment scheduled as my panel increases in size!! Hopef this is a fix that's coming soon.

Yes please! It would be nice to have the option to set-up the preferred work-flow: to charge or not to charge prior to completing the booking.
