Hey!
Thanks for reaching out to us!
I’m not sure if I’m following your request completely but hopefully this will be the information you’re needing.
When buying a license, it can be applied to a multisite install and the license can be used to update the files on that install no matter how many sites within the network are utilizing the plugin.
This will apply to all of our plugins and the pricing for each can be found on our website.
You will also have access to support via our forums if you run into any issues when using our plugins.
Let me know if this helps.
Thanks!
