An extension’s functions can be provided to its users for free or at a
cost. This section explains the different options available to the
extension developer when choosing how to charge money for their product.
When designing an extension, you need to choose between implementing
custom licensing and billing mechanisms for their extension, and making
use of a complete licensing infrastructure provided by Plesk
specifically for extension developers.
Custom implementation is possible, but it is unnecessary. Plesk enables
extension developers to use its own Key Administrator tool to manage
software licenses for their extensions. These licenses can then be sold
through the Plesk Online Store.
Making use of these tools saves a lot of time and effort. But there is
more:
- Plesk has a lot of resellers whose infrastructure is integrated with
Key Administrator. It will be easier for them to resell products that
also use Key Administrator for licensing. - It is easier for our numerous partners to purchase everything in one
place rather than going to different places for a specific item. - The single model of purchasing things is familiar and comfortable for
the users. - Plesk handles the billing by processing all payments, currency
conversion and certain country-specific taxes. - Plesk helps with advertising products licensed through us.
Considering all of the above, it is highly recommended that all
extension developers take advantage of the licensing tools that Plesk
provides. The following topics describe the different ways an extension
can be sold and the implementation details.
