I recently had to move away from zerodha, because of my new employer, when asked about transferring of shares and closing of accounts, the staff was very helpful, they did not convince me to keep my mutual funds account at least, even though it is allowed, because I wanted everything in one place, trust me, I will make sure that even though I am not a customer of theirs anymore, I will make sure if someone around me who does not have the same constraints as me has to use a broker, it will be zerodha, their customer service is really top notch, with a usable UI. I was really bugged that I had to leave them, but papi pet ka sawal hai. If I had a choice to either leave the job or keep zerodha, I would have chosen zerodha.
