What's the best referral software/solution for a two-sided service marketplace?

I'm building a service marketplace, similar to Upwork. I'd like to implement a referral program, where I can offer and track 2 different programs. One program for regular referrals (service provider & customer), and then one program for a small network who will work like a sales team, where I can give them a percentage of commission fees for referrals for a year, or some specific time frame. Ideal Requirements: • Unique referral links • Tracking and Payment system o Reward options: o Service Provider referrals: Flat Fee upon referral registration + commission on referred Service Provider's 1st job completed o Customer referrals: Flat Fee for for referral job posting Any help/guidance is very much…
