I've been producing on fl for almost a year but i didn't try to sell anything i only posted my beats on social media. But now I received a message from someone saying that he would like to purchase one of the beats I posted and so iam trying to figure out how to sell this beat. I wanted to sell it with beatstars but i dont really know how to works and if i can sell it without buying a selling licence on beatstars. So should i sell it on Beatstars or other website? Or should i send it directly to the person and he will send me directly money?
