So you are saying the client has to notify ato about the new SSID? I did notify ato about the client new SSID (through my own access manager).
So you are saying they have to do it using their own details and I cannot just add it myself through my access manager.
They don't have access manager, so they need to contact ato by phone as per the step mentioned by Shella A, I assume.
What about BMS Id, Is it the same one I provided to ato ( as a tax agent) or the client has a different one as well?
By the way, that was not the case when we were using AR..
