Earn Once and forever
The 37signals Affiliate Program pays you once after a customer's first monthly payment, plus 5% of that customer's future monthly fees for as long as their account remains open. This means you earn recurring revenue for each customer that signs up through your affiliate link.
Get paid often
As long as your affiliate earning are over $100, you'll be paid every 45 days. If you haven't earned $100 since your last payment, we'll pay you 45 days after you've crossed the threshold. Payments are made via PayPal. If you don't have a PayPal account you'll get one with your first payment.
