Selling product- subscription model

My client wants to offer a couple of their products on a subscription basis. Meaning either you can buy it once or sign up for a monthly subscription (with a discount…)
I googled and see there seem to be different options for plugins etc…
The site is using Woocommerce.
(Client mentioned something about using paypal subscriptions? but I am not familiar)
Does anyone have experience with this that can offer advice?

Woocommerce have subscriptions that work well, if you need more details then let me know.

Thanks… where can I find out more info about this… is it a plugin, extension?
