Servers can earn money on Discord by offering Server Subscriptions (a tiered monthly subscription that provides access to exclusive content) and Server Products (currently in beta testing and available to a select group of servers).

Server Subscriptions give you the ability to create subscription tiers for paying members, offering them premium experiences with unlockable servers and channels.

Server Products are digital products that are sold as one-time purchases. These products are customizable and managed within your Server Shop. We don't offer support for physical good fulfillment.
