Affiliate Plus lets your registered users get credit for new users they recruit by sending people to any url on your wordpress site with ?affid=username appended to the end. This will set a cookie on the visitors computer, which tracks who they have been referred by.
You can select who gets the credit for the referral: the first affiliate who send the user to your site or the last (cookie is overridden with new affiliate ID) You can also specify for how long the cookie is valid.
Members can be redirected to any page you want when logging in (admin users will not be redirected)
You can see who has been referred by whom and how many new members have been referred by each user on the user list.

The Simple Woo Affiliate Tracking simply (ha!) tracks the sales driven by any URL appended with a ‘refid’.
For example:
www.yoursite.com/?refid=lj419275070985lkhj0
Any body who clicks through that URL and buys a product through your store will have that unique ‘refid’ attached to their order.
This allows you to add your own refid to any link you want to distribute. You can export the number of sales assoicated with the id at any time through “Tools”>”Simple Woo Affiliate Tracking” into a .csv file.
How it works:
The plugin detects the ‘refid’ appended to the URL and stores it in a cookie. During checkout, a ‘refid’ field is added to the checkout form (in a hidden state), and that field is set by plugin Javascript.
