Assalamu alaikum! Currently I own a membership site which sells traffic. I pay free affiliates 10% on sale and upgraded members 50% on sale. Upgraded members actually purchases traffic and they can also earn more money on sale when compared to free members. Is there anything wrong on paying upgraded members a lot? Is it involved with riba? Please clarify my doubt.
There is nothing wrong with what you have explained. Riba (i.e. interest) is not applicable in your case. Riba is basically a fee on a financial loan. This can be small or great, as long as there is a charge exceeding the original loan amount and is a percentage related directly to the money borrowed. Your circumstances do not create a borrow and loan situation; therefore, it is not relevant to the prohibition of Riba. Additionally, nothing in your business model, from what you have explained, goes against the Shari’ah.
I hope this helps.
God knows best.
