Go to Market Pro Max –> Affiliate Center and click on the Affilates Results tab.
This page is where you will see the statistics of your affiliates. To view sales for any given month, go down to the Affiliate Sales Reports. Here you can search by month or by email (the default is month) and when you click submit all of the sales reports will display.
All sales for that month will be displayed showing you how many referrals or sales each affiliate has made, what their revenue is, whether the commission has been paid yet, etc. You can also then export these results.
