I am a freelancer and a client gave me this query and i am unable to solve if anyone knows kindly give me a suggestion and guidance. Can we create such a system in Shopify that 2 types of people come to our store, one of them is doing normal shopping and the other is if they are resellers. So, is there any way that when a reseller comes to our website, we will know that it is a reseller? Apart from that, can it be that we pay him for bringing some of the people he is referring to our website, but we don't have to do all the calculations and let Shopify tell us by itself?
