I usually see them charging me if you are a ruckus dealer 1 year of support and firmware upgrades is 10% of the cost of the controller.
Not retail cost your cost. So say your cost for the zone controller is like $900, so for 1 year of Partner preimium support (meaning I support the customers calls first tier) and one year of updates it costs your roughly $90 for the zone controller. For a Ruckus AP lets take the 7363 its like $45 for 1 year partner premium support.
What you charge the customer for your support time is up to you. Partner premium support is NOT available to the end user. There is another end user support program that is more money where the customer calls Ruckus direct for support if needed.
Projects like this I like to be the first point of contact and have them pay me for support. Since you know the layout of the system etc.--
