Plesk offers extension developers the option to sell commercial extensions on the Plesk Marketplace.

Paid extensions sold on the Plesk Marketplace must integrate with Plesk licensing via Key Administrator.

Extension licenses can be sold in the Plesk Online Store, and also via Plesk Partner Central. Doing so saves extension developers a lot of time and effort. On top of that:

• Plesk partners’ infrastructure is integrated with Plesk Partner Central. Resell products that use Key Administrator for licensing makes reselling them easier, giving those products a leg-up.

• The single model of purchasing licenses is familiar and comfortable for the users.

• Plesk handles billing by processing all payments and currency conversions, and also collecting certain country-specific taxes.
