Syncing Multiple Google Calendars

[SimonMac]

ClientCo and ClientOfClientCo both use Google Calendar, I know I can subscribe to one from the other so I can see both diaries in a single view but this doesn't help when people are scheduling in one diary but I have a clash in the other.

Anyone know of a service which can sync the two properly? I don't mind paying

I think there's a way to merge the two but not sure if that is visible to externals

I spent ages trying to do this for our two domestic calendars and failed. As far as I could tell, Google had actually removed the level of functionality that would have made it possible.

Closest I got was having a shared view of one of them and making that the default for all new entries, but that solution won't work for you on different networks and unrelated user credentials.

Presumably you get notifications of new entries on one or both calendars. It might be possible to construct a rule to create the relevant entry in the "other" one, but it still wouldn't allow you to prevent clashes across the two.
