For some clients I like 100% online only, but for others I still like an appointment.
Many clients are smart and efficient, and so it's great to proceed online.
But others will never sign and finish, asking a string of creeping questions and corrections. And I have to spend time giving them deadlines to provide more info and to sign, etc. It's just a real PITA with some clients.
Without an appointment it's also easy to miss the need to convey valuable things, such as "do you plan to sell this property that you just moved out of and now rent to others?" Etc.
It also creates a connection with clients that increase loyalty, value-add, and the ability to bill.
Plus it's "the relationships" you remember on your death bed - not how much money you made.
I also have a nice handful of elder-clients and I really like them because they are organized and show up on time (early, LOL). They couldn't handle online and I prefer not to lose them. I can replace them if I wanted to, but I like them.
I'm not saying that appointment-less is folly, I'm just making a point that appointments as still helpful in many ways and with many clients.
