Charge up front is LIVE (Patreon)

"New Patrons: New  Patrons will be charged on the day they become your patron, giving them  access to all content shared with their reward tier. On the 1st of the  following month, they will simply return to being charged monthly at the  beginning of the month.

 Existing Patrons: Your  existing patrons will be charged on the 1st of the month like usual.  However, if they increase or decrease their pledge the month you switch  to charge up front, they will be billed immediately in full." 

You can read more here and here.
