Who controls your time? It can feel like your clients control your time, or your friends, or your kids, or your spouse. When you find yourself saying you don't have enough time, you may really be saying that you are not spending the time you do have in the way that you want.
Don Orlando has a great take on managing your time that he shared in a recent issue of the Spotlight. He talked about charging clients extra for projects that require him to work evenings or weekends. His surcharge is something like $4,000 on top of his usual rates.
I do charge a rush fee (usually 20%), although I try not to encourage it. I found myself doing one yesterday though, and the client had delayed getting me his information until about 9 p.m. last night. Fortunately, I had started writing the draft without the information he was supplying, and it didn't take too long to plug in his new information. But as I was sending off his draft at 11:30 last night, I pondered increasing my rush fee even more.
Maybe I'll make it a flat $500 for 24-hour turnaround. You have to start somewhere, right Don?
