I have 100 clients and 100 domains. I'm using WordPress Multisite to run them all. For their convenience, they pay me for hosting and maintaining the ownership of their domain name (which I do all through one hosting company). I control every aspect of their website. I am killed instantly in a car accident.
What steps should I take to prepare for an event like this if I have no one to rely on? My friends and family are barely computer literate. Even if they have my hosting name and password, they'd be lost as to how to divvy up everyone's sites and access.
If you have an answer, PLEASE PLEASE be thorough. I want to provide the best possible solution for my clients.
