You don’t have to pay UnitedMasters any upfront fee in order to sell beats through the Beat Marketplace. However, a connected Stripe account is required so that you can accept payments. Stripe charges 2.9% plus $0.30 for every transaction.
UnitedMasters will take 10% of beat sales for producers who choose the standard UnitedMasters Producer deal. UnitedMasters does not take any percentage on beat sales from producers who subscribe to a monthly SELECT subscription. For more information on SELECT Producer subscriptions, please see this article.
Please note that a SELECT Producer subscription is separate from an artist subscription which provides a different set of benefits, and paying for one does not automatically enroll you in the other.
