Ask How do you set up monthly membership option?

[SuperAffiliateX]

I want to offer a monthly membership on my site, but I don't know where to start. Do I need special software or plugins? How do I set up payments so they renew automatically? I also want to make sure members can cancel easily if they want. Should I offer different pricing tiers or just one plan? I don't want to make mistakes that could cause payment issues later. If you have a membership site, what's the best way to set up a monthly membership option?
