One thing this article doesn't mention are affiliate sales which depending on how far you want to go can be a decent amount of work. This is the system that lets other people get commission based payouts for sales within your platform. You need to track affiliate codes back to sales and a user, handle sending payouts to an affiliate at their configured payment provider and if you want to go all out then handle metrics around visitors and present a UI to the affiliate so they can see their conversion rates and payout history. Fortunately most of that can be built incrementally. As long as you associate a unique code to a user and wire up associating that to a sale with a specific commission % amount everything else can be done manually or skipped. For example I pay affiliates out once per month where I goto Zelle or PayPal and send out the payments. It takes less than 10 minutes. There is no front end for tracking conversions and it's also never been a cause of someone saying they don't want to be an affiliate because of that.
