Every customer account automatically includes Affiliate capabilities. If you have a customer account, you can also earn at the 30% Affiliate rate on every subscription payment a referral makes.
You choose your own invite code when you activate. It can be 3 to 20 characters, lowercase letters and numbers, and the portal checks availability as you type. Your code becomes your referral link, so pick something you are happy saying out loud.
Open Settings > Affiliate to copy your code and referral link, and open Earnings in the sidebar for your referral list, commission structure, and payouts. There is no separate Affiliate application required for existing customers, though you do have to activate once.
Customers whose referrals convert consistently are invited to apply for Partner status.
