Have you lost clients before because of your negligence?

[Btaliat]

It is not a new thing for freelancers to lose clients. It does happen. So freelancers don't need to feel bad if such a thing happens. The only thing they need to do is to make sure that they get themselves corrected for the same mistakes not to be repeated again. You need to make sure that you get the details of what your clients want. Let them know that you are capable of doing the tasks as they want.
