Affiliate Script or Program question for web hosts

[hosts-com]

Hey, I just wanted to know how do you create an affiliate program where your customer will get a monthly portion of every sale that you make, which is referred by your customer. Do you use scripts or do you do it manually and you do use PayPal as your method of payment, right?

Ours is semi-automatic. We write scripts to automate various functions as time permits or as needed.
