We have a referral program for FunnelFlux Pro, you can sign up here - https://partners.funnelflux.com/
Note we approve all new partners. Once approved, we can also create a partner page for you, which you can direct link to if desired (rather than using redirect/affiliate links). That page will then set referrals to be from you, regardless of how the user got there.
Our commissions are a flat 25% on all revenue, so you won't receive commissions until users have converted from their trial to being a paid member. Payouts can be done automatically within the system by you, via PayPal, and are NET30 since we need to allow time for refunds, chargebacks etc. that may occur.
