Crazy as it is, clients often ask me to do some sort of work on their website, then a week later they change their mind and I undo it. I don’t really mind — I’m sure they have a good reason. But I will still bill for that work, even though it is not showing up on their website. It’s not my fault or responsibility if the client changes his or her mind after the work is done.
Sometimes there may be a legitimate need to backtrack, but my experience is that some clients don’t think ahead far enough, or think carefully enough about their objectives. They come up with a great idea, want to see it take shape immediately, and ask for it. All well and good — but perhaps if they had run through it with other staff members, or solicited feedback first, they might have come to the conclusion that the work should not be done.
