In my site I have the option for clients to manually pay me at their appointment or pay in advance.
If they pay in advance via paypay this is fine the status of the appointment changes to paid and auto syncs with my google calendar.
If they choose manual payment (i.e pay me when I carry out the appointment) then the status remains pending and the appointment doesn't auto sync to my calendar. I've installed the add on I found in another thread which sends me an email for a pending notification. Which helps me change the status from pending to confirmed which then syncs the calendar.
But I think I would like all pending appointments to auto sync to my calendar. Or ideally have another status of "manual payment requested" which then also auto syncs to my calendar.
I'm using marketpress.
I hope that makes sense!
