Hi, please can someone assist. I would like to customize the recurring billing. My subscription service has the option for quarterly billing, at the moment my only options are day, week, month, year. I would like to add an option of every 3 months. Anyone know how i can do this?
Many thanks

There's a "Cycle" field for recurring profiles, which is how often it happens for the time period you choose. So you'd set yours to "3" and then choose "Month", and it should cycle every 3 months.
