Affiliate Wiz version 3 and higher now supports tracking recurring commissions.   You can now pay your affiliates each time you collect money from a customer the affiliate sent you.  For example, if you collect monthly membership fees, subscription fees, hosting fees, etc. you can now reward your affiliates each month for the money you collect.

How does it work?  You enter the recurring sale into Affiliate Wiz.  You define how frequent and how many times the recurring commission will be credited to the affiliate.  For example, if a customer signs up for a 1 year subscription charged at $49 per month, you can credit the affiliate each month for this sale.  If the affiliates commission rate is 10%, they will be credited $4.90 each month for the annual subscription.  Once entered, Affiliate Wiz automatically credits the affiliate each every month!
