As of right now, affiliate coupon are only applied on the first payment. We need to be able to have the coupon applied forever.

For example, if I sell a SaaS plan with a free trial, the 10% discount coupon is applied to... 0€... because the first payment is the free trial...

Furthermore, the coupon needs to stay actif even if the client upgrades his subscription. Can you solve this please ?

PS : Another "Affiliate Coupon" feature -> I don't know if right now the Affiliate Coupon links the Client to the affiliate. Meaning, if a client uses a coupon without using the affiliate link, does the client is tracked and assigned to the affiliate ?

That would be super useful, especially if Coupons trump Links (meaning, if Affiliate A's link is used by a client BUT this client uses Affiliate B's coupon, then the sales is assigned to Affiliate B)
