What is the best plugin to charge(monthly, yearly) AUTHORS(members) for plugins like ‘ULTIMATE MEMBER' or PROFILEGRID(profilegrid.co)?
I have been searching quite a time for a solution. There are many plugins for paid content but I didn't find a payment solution yet to charge authors (who can enter their profiles and write blogs).
Setting up ULTIMATE MEMBER or PROFLIEGRID is quite easy. But I still didn't find a plugin for charging those members on a monthly/yearly base.
Thanks for any help.
