Optimized Sense's development policy for any Plugin development is as the following:
No Source-code delivery (We deliver the Plugin without Source Codes).
We have the right to re-sell the Plugin (The Plugin is under our copyrights).
The client will purchase license(s) of the Plugin (Covered within the development costs). The client can purchase as much licenses as he want later on. Note that each license will work for one system only (The white label is called another system). So the logged in dealer must be within the system's tree.
