In your original post you said that you would be notifying clients that call "too much" that you will start charging.
How do you notify clients? I mean, what do you say?
I would love to do this, but I don't want to "turn off" the clients, or have them not call me if it's relatively important assuming I want to keep that client.
So, my question is: How does one tactfully tell a client I am not available 24/7 for questions that are not relevant?
