How can we improve WHMCS?

You can create products with the auto-release server module.
This is for products where an automatic setup isn't available, for example by a not supported module.

However, this would also be handy for server types that aren't supported by WHMCS, a server that isn't running on Plesk, direct admin or cPanel. But uses the datacenters own custom-made system.

With this module, it would be possible to assign products with auto-release module to this server, so you can still have a network status page, have an overview of what clients are on which server, etc.
