@brianjking We actually don't handle those kinds of updates. We're geared towards the plugin developer and help them push new plugin & theme updates/versions to their customers either manually through our system, or using a system like Git or Bitbucket where we can do auto-deploy based on a versioning file. The updates appear exactly as they would for plugins & theme updates from the WordPress Repository. To help with the premium themes & plugins sold through Envato Makretplace, we also have purchase code validation.

Hope that clears things up!
