Create One time redeemable codes with subscription

Hey guys,

I was wondering if you guys could help me with an idea I want to execute.

So I am creating a subscription service in which the user either pays 4.99 or 9.99 to get a percent off a bunch of stores monthly. But they can only use the coupon once a month per store.

I am thinking creating a QR code that is scanned at time of purchased, and cannot be used again until next month. The coupon code could maybe be the same monthly, but when its used, it will re-activate in 30 days. And then i would have to create one per user and per store.

I know Woocommerce has coupon codes, but this will need to be separate since its for a subscription.

Any plugins you guys suggest i can use for something like this?
