Estimates/Guarantees/Payments
I am in the process of starting up a new computer support business. I am going to be doing hardware/software support and general technical consulting.
How do you communicate your rates/estimates to your clients. A lot of times I need to come in and take a look at there situation before being able to estimate. I got burned by a guy because he said he "misunderstood" what I quoted him so he was unwilling to pay me after the services was done? I am working on an estimate form so I can write this information down, but what language do I use to make sure I have something in writing that he will pay.
What is a clients responsibility in making sure that something was fixed correctly? I have often come in, fix something, made sure it did everything I know it should do, leave and two weeks later, they call back and say this functionality doesn't work on this machine, so fix it and i am not going to pay you for it. Meanwhile I did fix EVERYTHING they told me about.
What kind of guarantee do you give on your work? If you go in and fix something and it works for a few weeks and they call back and say that it doesn't work anymore, do you charge them for the call? What if they sit on it for a month?
My goal is to partner with the companies I work with and make sure that their computers/software works the way they need to. But with out their help I am doomed to fail. How do you promote that kind of relationship?
