Simmer Pro can be activated on any WordPress Multisite Network. Each new site requires a separate activation key and email address and license keys cannot be re-sold through a Multisite system according to the Simmer purchase agreement. 

If you are not re-selling license keys or re-packaging them in any way, the Simmer Pro Business plan is ideal for multisite instances under one owner with a total of five keys for up to five sites. If you need additional keys, simply purchase an additional pack or contact support for additional pricing information.
