That is precisely what i was looking for, just a number to track the sale, whether the invoice no. or a reciept, or a sales code just so that i can use it for now to track the sale. I want if the affiliate who made it possible for the sale to be able to ask for his commissions by confirming that indeed he was the one who made it possible. I don't know how to do it better for now for i have an mlm program working away from joomla and it should reward any affiliate who forwards a sale to the site. Is there a better solution? The mlm for now is can not track sales so everything will have to be mannually done. I am working on one that can track sales from affiliates. If there is a suggestion i will appreciate. Thanks alot.
