I and my brother work online as the freelance developers through a platform called Fiverr. I gave an interview to a client in November/December 2020 in which I mentioned that we will both work for the client but I did not work with him until April 2021, because I was working on another job back then. Fiverr mentions in their terms and conditions that all communications and money should only go through their platform on which they charge around 20%. However, my mother said to get payments directly from the client from now on because the client is kind of permanent now and we have already paid a lot of commission to Fiverr so there is no need to pay.
My question is that is it halal if I get the payments directly? I work for the client on monthly basis and I have to pay a hefty amount to Fiverr each month. Also, Fiverr's headquarters are located in Israel so I don't want to do business with them. Can I close my account on Fiverr and get the money from the client directly because I would no longer be obliged to their terms and conditions? or is it not even necessary to close the Fiverr's account?
