Invite people to Zetlis. When someone you invite becomes a paying subscriber, you both get bonus credits.
When someone signs up with your link and subscribes, they get bonus credits on their first payment — 25 on Starter, 50 on Pro, 200 on Business — and so do you.
You earn 10 credits for a Starter referral, 20 for Pro and 50 for Business.
On a paid plan you'd earn 25 / 50 / 100 instead.
Referral bonus credits expire 30 days after each reward is awarded. Every reward has its own 30-day clock — a later referral never extends an earlier one.
Rewards are granted once, on the referred account's first paid subscription. Renewals, plan changes and re-subscriptions don't count.
Once you've joined — even through someone else's invite — you get your own link and can refer others exactly the same way.
