Killing the Roach: The Incredibly Illogical, Fundamentally Odious — but Seemingly Ineradicable — Billable Hour
The service the lawyer renders is his professional knowledge and skill, but the commodity he sells is time — Reginald Heber Smith, inventor of the billable hour
Both reviled and ubiquitous, the billable hour is the roach of the legal world — Douglas McCollam, writing in the American Lawyer
Let's imagine that you would like to have your dilapidated, wood-sided house painted. The southern exposure is peeling, the soffits sport dark Rorschach patterns of mildew, and more than a few window sills have that uncomfortably punky feel to the touch that whispers "we're rotting — you must help us." You know that you can't put off facing the music any longer, and hope that the impact on your wallet will be no more painful than absolutely necessary.
So you do what any rational homeowner would — you get some referrals from people you trust, call the folks they recommend, and tell each of them that you'll be soliciting several bids. While you're at it, you also call the painter who, as luck would have it, had dropped a flyer in your mailbox that very afternoon.
Over the next week each housepainter stops by after work, walks around your house, scribbles a few notes, and promises to get back to you with a quote. Within a week, most of them actually do. Like any homeowner would, you select the cheapest, failing to note that it came from the painter you found through the flyer. Soon, the job is done, and he drops by to collect the agreed upon amount. Pleased, you pay him on the spot.
What a nice, logical system, especially for the buyer. You know just what you'll have to pay before you commit to pay it, and gain the benefit of competitive bidding as well. You'd be crazy to take on such a large financial commitment any other way, wouldn't you?
